Description

Background Art

[0001] In industrial environments, control systems are used to monitor and control industrial processes, inventory of chemical processes, etc. Typically, control systems perform these functions using field devices that are distributed at key locations in the industrial process and coupled to control circuitry in the control room through process control loops. The term "field device" refers to any device that performs a function in a distributed control or process monitoring system, including all devices used in the measurement, control, and monitoring of industrial processes.

[0002] The process control and measurement industry uses field devices for a variety of purposes. Typically, such devices have field-hardened housings that allow them to be installed outdoors in relatively harsh environments and withstand extremes of temperature, humidity, vibration, mechanical shock, etc. These devices can also typically operate at relatively low power. For example, currently available field devices receive all of their operating power from a known 4-20 mA loop.

[0003] There are several different types of field devices. Such devices include process variable transmitters, which include or are coupled to process variable sensors and provide an indication of the process variable to the control system. Field devices also include actuators, such as valve controllers and positioners, that can generate a physical output (i.e., the position of a component) based on signals received from the control system. Field devices also include instruments or displays that can be installed at key locations in the process environment to indicate process variables or conditions. Field devices also include sensor assemblies that are mounted to process pipes, tanks, or containers (referred to herein as fluid handling equipment) and electrically coupled to the process variable transmitter.

[0004] Field devices are usually mounted to the process facilities (e.g., process pipelines) to which they are connected. This installation presents some challenges because the fluid handling equipment (pipes or vessels) may experience large temperature changes and mechanical vibrations. However, even under such conditions, the field device mounts need to maintain their mounting position firmly. Summary of the invention

[0005] A field device mount includes a connector configured to be coupled to a field device. A clamp foot is coupled to the connector and is configured to engage fluid handling equipment. A tensioner assembly is coupled to the clamp foot and includes a tensioner bracket. A biasing member is configured to urge the tensioner bracket away from the clamp foot. The strap is configured to pass around the fluid handling equipment and coupled to opposite sides of the tensioner bracket. The buckle is configured to provide a clamping force to maintain tension in the strap. A field device mount using an inline tensioner and a method of coupling the field device mount to fluid handling equipment are also provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The embodiments described herein generally utilize a known process called strapping, in which a relatively thin strip of material can be wrapped around one or more objects to be strapped, and then tensioned, clamped and cut to keep the objects in the strapping position. Utilizing this strapping process to install field devices to process pipelines provides significant improvements over previous methods. Previously, each different pipe size required a unique saddle clamp size, but now, only a strapping band is cut to the appropriate length according to the pipe size to be used for the field device mount. This allows manufacturers to stock reels of strapping material, which can be simply cut to the appropriate length once the field device mount is ordered. The strapping process also allows the field device mount to be removably installed around a tank or container, which is an improvement over previous welding attachment methods.

[0032] To tension the strapping, known strapping tensioning tools may be used. Typically, a buckle is first attached to the strapping, and then the strapping is wrapped around the fluid handling equipment and passed through the buckle. In the case of a field device mount according to embodiments described herein, the strapping is instead wrapped through a tensioner bracket, but otherwise the strapping operation is substantially the same as a typical strapping process. The tensioner tool pulls the loose end of the strap tight, and the buckle secures the strap.

[0033] To accommodate the temperature range of field device mountings, different strapping materials can be used to suit the application requirements.

[0034] In recent years, the use of surface mounted (i.e. mounted to the exterior surface of fluid handling equipment such as a pipe or vessel) temperature measurement devices has become a popular alternative to direct temperature measurement methods such as traditional thermowells. These surface mounted devices can provide a non-intrusive measurement point for measuring the external temperature of the pipe or vessel surface.

[0035] Figure 1 is a schematic diagram of a measurement system using a prior art mount. The temperature measuring device 12 is spring loaded and is configured to contact the outer diameter of the pipe surface held in the pipe mount 14. As shown, the pipe mount 14 includes a pair of semicircular saddle clamps 16, 18, each of which has corresponding ears 20, 22 pushed together by fastening hardware (e.g., bolts 24 and nuts 26). As can be understood, the curvature of each semicircular saddle clamp 16, 18 is very close to the outer diameter of the pipe to which it will be installed. Therefore, in order to make the system 10 compatible with various process facilities and pipes with different diameters, saddle clamps of multiple sizes must be manufactured and stocked. Although this solution provides a secure connection to the pipe, it is generally relatively costly and requires different saddle clamp sizes for each pipe size. This brings challenges to the inventory, delivery and installation of the fixture to companies and customers. As the size of the saddle clamp increases to support large diameter fluid handling equipment, the environmental impact of shipping the pipe mount to customers and the safety risks during manufacturing and installation will increase.

[0036] According to various embodiments described below, a field device mount is provided that can adapt to the size of fluid handling equipment and does not require a different clamp for each different pipe, container or equipment size. In addition, the embodiments described herein are able to compensate for small changes in diameter that occur during temperature changes through thermal expansion and / or contraction. This helps ensure that a sturdy mount is provided regardless of the differences in thermal expansion between the fluid handling equipment and the clamping system.

[0037] Although about Figure 1The pipe mount design shown provides a rigid connection around the exterior of the pipe, but is sometimes susceptible to differential thermal expansion / contraction and / or vibration.

[0038] Figure 2 is a schematic diagram of a field device mounting base according to an embodiment of the present invention. In order to provide a solution that can be used for a variety of fluid processing equipment sizes and materials, Figure 2 The proposed field device mount utilizes a clamp foot 102, a flexible crimping band 104, and an inline tension retention feature 106. The combination of the flexible crimping band 104 and the tension retention feature 106 means that the field device is able to maintain adequate clamping force regardless of changes caused by thermal expansion or contraction. The field device mount 100 allows for a variety of methods of attachment to the fluid handling equipment 101. Figure 2 A dual belt configuration with an in-line tensioner 106 according to a first embodiment is shown. As shown, the belt 104 is wrapped around the fluid handling equipment 101 on top of the clamp foot 102. The field device mount 100 includes a connector 105 that is internally threaded to receive a field device. In the example shown, a spring-loaded sensor adapter 103 is screwed into the connector 105 to position a spring-loaded temperature sensor on an outer surface of the fluid handling equipment 101. The spring-loaded sensor adapter 103 preferably provides a fire / explosion barrier. The connector extension includes a connector 105 and a rod 322 that is assembled into the clamp foot 102.

[0039] Figure 3 FIG. 2 is a schematic diagram of a field device mounting base according to another embodiment of the present invention. Figure 3 As shown, the field device mount 120 continues to employ the clamp foot 102, but has only a single strap 104. The single strap configuration utilizes a single compression spring (e.g., a wave spring) 160, which is guided by the central axis of the connector extension, the rod 322. In this example, a buckle or any other suitable structure can be used for strapping. In this embodiment, the strapping strap 104 is fixed to the tensioner bracket 124 along the central axis, which compresses the spring 160 when the strapping strap 104 is tightened to secure the field device mount.

[0040] Figure 41 is a schematic cross-sectional view of a fixture foot according to an embodiment of the present invention. The main contact component of the field device mounting seat according to each embodiment described herein is called a fixture foot 102, which holds the field device substantially perpendicular to the fluid processing equipment 101 (axially and radially) and interfaces with the surface of the fluid processing equipment 101. The fixture foot 102 generally has a V-shaped profile, which provides several advantages over a flat-top design. On the contact surface of the fixture foot 102 is a v-groove 130, which is created to provide the highest stability for the largest range of fluid processing equipment sizes. In a specific embodiment, the v-groove 130 has an angle of about 160°. When the strapping band 104 is tensioned, the top profile allows the force to be evenly distributed on the surface of the fixture foot 102 (schematically shown at arrow 132) to avoid high stress concentration. Compared with a fixture foot with a flat top, the fixture foot 102 allows the strapping band 104 to contact the entire surface of the fixture foot 102, thereby distributing the stress on the outer surface of the fixture foot 102.

[0041] Figure 5A 1 is a schematic diagram showing an inline tensioner assembly in more detail. As shown, the inline tensioner assembly 106 generally includes a pair of band engaging elements 136, 138, each of which is configured to allow a fastener 140 to pass therethrough. A compression spring 142 is disposed around the fastener 140 and captured between the band engaging portion 138 and a nut 144. When the nut 144 is rotated, the compression spring 142 will change the degree of compression.

[0042] Figure 5B is a schematic diagram of the in-line tensioner assembly 106 in a tensioned state. Figure 5B As shown, when a band (not shown) applies force in directions 146, 148, the band engaging portions 136 and 138 are pulled apart against the bias of the compression spring 142. If there is any change in the diameter of the fluid handling equipment (e.g., due to thermal expansion or contraction), the distance between the band engaging portions 136, 138 will change accordingly and maintain substantially the same tension by virtue of the bias of the compression spring 142. To properly set the tensioner assembly 106, the end user will typically tighten the strapping band until the compression spring 142 is compressed a predetermined distance. This distance may be indicated by physical markings on the tensioner (e.g., by markings 150 on the fastener 140) or by an installation manual. To uninstall the field device mount, the inline tensioner nut 144 is slowly unscrewed from the fastener 140, which will gradually release the compression spring 142 and remove all potential energy in the inline tensioner 106. Once the compression spring 142 releases its force, the strapping band (not shown) can be safely removed from the field device mount 100.

[0043] Fig. 6Ais a schematic diagram of a clamp foot 102 combined with a vertical tensioner assembly according to an embodiment of the present invention. For single belt installation applications (e.g. Figure 3 160 is a clamping device that is used to tighten the strapping strap 104 (not shown) using a single compression spring 160 that is guided along the rod 322 of the joint extension. The strapping strap 104 (not shown) is coiled over the strap engaging portions 162, 164 on the tensioner bracket 166, which is guided on top of the compression spring 160 on the central axis. When the strapping strap 104 is tightened, the compression spring 160 is compressed and the clamping load is equal to the spring force applied to the clamp foot 102. Similar to the in-line tensioner assembly 106, the strapping strap 104 is tightened until the compression spring 160 is compressed to a predetermined distance, which is preferably represented by a physical mark or measurement provided to the user. To uninstall the assembly, the locknut 168 on the central axis is tightened onto the tensioner bracket 166 until the spring 160 is further compressed. The compression spring 160 further relieves the tension on the strapping strap 104 and allows the strapping strap 104 to be safely removed. Once the strapping band 104 is removed, the locknut 168 can be loosened to its original position, thereby safely decompressing and releasing the spring 160. Figure 6B 1 is a schematic diagram of a vertical tensioner assembly in a compressed state. The strapping generates forces as shown by arrows 170 , 172 to resist the force of the compression spring 160 .

[0044] Figure 7 is a schematic diagram of a field device mount according to another embodiment of the present invention. Although the embodiments have been described so far with respect to a vertical tensioner or an inline tensioner using a compression spring, other types of biasing members may also be used. Figure 7 As shown, a series of stacked disc springs 200 are used in the vertical single band tensioner assembly. Because disc springs 200 of this form factor have a much higher spring rate than similar wave springs or coil springs, the use of a series stack of disc springs can achieve both sufficiently large spring forces and spring travel distances, making it suitable for use in a variety of mounting methods, including remote mounting and integral mounting (as shown) of field device assemblies. The field device 201 is connected to the connector 105 and includes a field hardened housing 203 and a local display 205, which significantly increases the mass that needs to be supported. Compared to the field device mount 120 with compression springs 160, the significant clamping force and effectiveness of the field device mount 603 with a series of disc springs 200 allows the field device 201 to be directly mounted to the fluid handling equipment 101 without the need for remote mounting.

[0045] Figure 8 yes Figure 7 An enlarged schematic cross-sectional view of a portion of a vertical single-band tensioner assembly is shown. Figure 8Shows how to use washers with a conical shape in alternating orientations to create a disc spring assembly of any size. The conical shape gives each washer its flexible effect and when stacked together, creates a high spring rate assembly.

[0046] Fig. 9 FIG. 2 is a schematic diagram of a vertical tensioner assembly according to another embodiment of the present invention. Fig. 9 As shown, the vertical single-band tensioner assembly can also utilize a leaf spring 202 as a biasing member. The leaf spring 202 extends along the clamp foot 102 and helps the field device mount resist vibration along the axial direction of the fluid handling equipment 101, while also ensuring that the strapping band is tensioned during expansion and contraction.

[0047] Fig.10 2 is a schematic diagram of a field device mounting base according to another embodiment of the present invention. As an alternative attachment method for relatively small pipeline sizes, the clamping foot 102 is pressed against the fluid processing equipment 101 by a v-bolt clamp 204. As shown, the v-bolt clamp 204 generally has a "V" shape and a pair of threaded ends 206, 208 that pass through the aperture of the beam 210. Fasteners (such as nuts 212) are screwed onto the ends 206, 208 to generate a significant clamping force between the clamping foot 102 and the fluid processing equipment 101.

[0048] Fig.11 Schematic diagram of a field device mounting base according to another embodiment of the present invention. Fig.11 The design shown is similar to Figure 3 The designs shown are similar and like parts are numbered similarly. However, Fig.11 The embodiment shown is Figure 3 The embodiments of the present invention differ in several important respects. The field device mount 300 includes an inlay 302 disposed between the fluid handling equipment 101 and the band 104 and the fixture foot 102. The inlay 302 acts as a corrosion barrier (primarily against electrochemical corrosion) between the fluid handling equipment 101 and the strapping band 104 and the fixture foot 102. The inlay 302 includes a cutout for the sensor and optional retaining tabs that attach together to hold the inlay in place. The field device mount 300 also includes a locknut 168 and a retaining tab as a counterweight. Figure 3 The improved stacked disc spring 200 of the compression spring 160 in FIG. Fig.11As shown, the field device mount 300 utilizes a modified tensioner bracket 304 having a pair of ears 306, 308 configured to receive corresponding removable pins (e.g., U-shaped pins) 310, 312. When the strapping band 104 is tensioned, the tensioner bracket 304 transfers force to the disc spring 200 until the proper installation tension is achieved. The removable pins 310, 312 allow the band to rotate and are secured by a fastener (e.g., a C-clip ( Fig.13 ) are secured to retain the pins 310, 312 to the tensioner bracket 304 while also allowing safe removal and reuse.

[0049] Fig.12 yes Fig.11 322. In addition, the rod 322 also includes a centering feature 324, which is configured to ensure that the temperature sensor inserted into the mounting assembly is centered within the rod 322, thereby achieving substantially vertical contact with the outer surface of the fluid processing equipment 101. This vertical contact is important for ensuring accurate temperature measurement. Fig.12 As can be seen in the figure, a seal 326 is provided in the connector 105 to prevent ingress to the field device 201 (not shown).

[0050] like Fig.11 and Fig.12 As shown, the improved tensioner bracket 304 provides significant sturdiness and helps locate the spring edge. In addition, the tensioner bracket 304 also includes ears 306, 308 for removable pins 310, 312. The tensioner bracket 304 has a substantially flat bottom surface for contacting the disc springs and includes sides formed as locating features around the first set of washers in the disc spring stack 200. The parallel ears 306, 308 have holes for the removable pins 310, 312 that retain the strap to the tensioner bracket 304.

[0051] Fig.13 1 is a schematic perspective view of a clamp foot 102 being tensioned in a vertical tensioner assembly according to an embodiment of the present invention. Fig.13 As shown, a pair of parallel ears 306, 308 are configured to receive removable pins 310, 312, which are secured in place by fasteners 340, 342. Fig.13 As shown, the tensioner bracket 304 includes a pair of opposing side walls 350 extending downwardly around the outer diameter of the disc spring 200 .

[0052] Fig.14 1 is a schematic diagram showing the rotation of the pin during installation. As shown, the strapping band 104 is folded over the pin and then secured to the buckle 380 (eg, Fig.12When the strapping band 104 is tensioned, each side is pulled and the removable pins 310, 312 are allowed to rotate within the tensioner bracket 304. This allows the strapping band 104 to rotate about the removable pins 310, 312, thereby causing uniform tension to be applied to the tensioner bracket 304 and the disc spring 200.

[0053] Fig.15 FIG. 2 is an unassembled view of a field device mounting base according to an embodiment of the present invention. Fig.15 As shown, the pin 310 is engaged with the strapping band 104. However, the strapping band 104 has not yet engaged with the removable pin 312. The strapping band 104 includes a loop that passes between the ears 308, while the removable pin 312 also passes through the ears 308 and the loop of the strapping band 104. Then, the fastener 340 is engaged on the removable pin 312 to retain the removable pin 312 in its installed position. The removable pin allows for safe removal of the strapping band and the field device mount. Pin and strapping band removal is performed by unscrewing the tensioning nut 168 and removing the retaining fastener 340 and removable pin 312 from the tensioner bracket 304. The tensioning nut 168 is screwed into the rod 322, thereby further compressing the disc spring 200 below the tensioner bracket 304. The additional spring compression loosens the strapping band 104 and allows the assembly to move freely for safe removal. Being able to remove the strapping after installation is of great value to the end user because the end user does not have to completely disassemble or require new strapping to move the unit. The assembly can then be reinstalled in another location with minimal installation time and effort. To reinstall, after positioning the strapping around the pipe, simply reinsert the pin and retaining fastener into the tensioner bracket 304 and thread the tensioning nut 168 back onto the top of the rod 322, thereby releasing the additional spring tension and transferring it back to the strapping, keeping the field device mount as originally installed.

[0054] Fig.23 is a schematic diagram of a field device mounting socket according to an embodiment of the present invention. Fig.23 An important feature of proper installation is shown which will ensure full benefit of the tension feature in the field device mount 300 because minimal torque or force is required on the disc spring 200. Most industrial strapping tools and applications do not require a specific installation torque or force, and known strapping tools do not have an indicator of the level of torque or force. To provide a specific amount of force, the embodiments provided herein may include a tensioner located in the rod 322 or inline tensioner 106 ( Figure 5B A physical mark 150 on the spring (as shown) may be provided to indicate the proper tension / spring compression. The mark may be calculated based on the spring force and correlated to a selected amount of compression in the biasing member. For example, for an ideal installation, the mark may be correlated to the compression of the disc spring.

[0055] Fig.16 is a schematic cross-sectional view of a field device mounting socket according to an embodiment of the present invention. Fig.16 An important feature in the form of seal 326 is shown. When used in conjunction with the above embodiments, seal 326 is implemented by a cylindrical seal (i.e., a wiper seal) that receives the temperature sensor at the connector 105 end of rod 322, which will prevent ingress to the field device and housing. Alternative seal designs may be utilized by those skilled in the art to provide ingress protection to the field device. Seal 326 allows the field device mount to be installed in orientations such as under a pipe, where water may accumulate inside the foot of the clamp but cannot drain. Seal 326 allows the assembly to maintain ingress protection.

[0056] Fig.17 FIG. 2 is an enlarged schematic diagram of a portion of a field device mounting base according to an embodiment of the present invention. Fig.17 As shown, as an enhancement, the field device mount preferably includes a centering feature 324, which includes an aperture 370 configured to receive and center the temperature sensor 372 within the rod 322. As designed, the centering insert is installed into the rod 322 and is retained by expanding into an internal groove within the rod 322. The centering feature 324 is used to align and center the temperature sensor 372 to improve surface contact, which is necessary to ensure continued heat transfer to the sensor tip and more accurate temperature measurement. Fig.17 Also shown is the operation of seal 326 sealing against the outer diameter of temperature sensor 372 .

[0057] Fig.18 is a schematic diagram of a buckle used in conjunction with an embodiment of the present invention. Buckle 380 may be used in conjunction with any or all of the various embodiments described herein. Buckle 380 is preferably a formed part and includes a set screw 382. The fixing of the strapping band is accomplished by screwing the set screw 382 through the formed buckle 380 and onto the strapping band 104. Cup end set screws are preferably used, while knurled cup ends and other types may be suitable for providing increased clamping loads. By holding the strapping band in place with a set screw, the same strapping band may be tensioned multiple times and may be tensioned to fit a variety of pipeline sizes. Alternative buckle designs may also be utilized by those skilled in the art as a secure attachment method for the strapping band 104.

[0058] Fig.194 is a flow chart of a method for installing a field device according to an embodiment of the present invention. Method 400 starts from block 402, wherein a field device mounting seat is set on a fluid handling equipment. Next, at block 404, a single strap is inserted into a buckle. The buckle can be a known buckle for a standard strapping process, or it can be an alternative buckle, such as a buckle that allows easy removal of a set screw to release the strapping. At block 406, the single strap is looped around a first strap engagement portion of a tensioner assembly (e.g., a vertical tensioner assembly). At block 407, the single strap is then passed around the fluid handling equipment to which the field device is to be installed. Once the single strap has been passed around the fluid handling equipment, it is looped through the second strap engagement portion of the tensioner assembly, as shown in block 408. Next, the end of the single strap is passed through the buckle again, as shown in block 410. At block 412, the strap is tensioned until a selected tension amount is reached, as shown in block 412. The selected tension amount may be indicated by markings on the field device mounting base (as shown in block 414), or by measuring spring compression (as shown in block 416). Other forms of determining the correct tension amount may also be used, as shown in block 418. If additional straps are to be applied, such as with respect to Figure 2 In the illustrated embodiment, the method 400 will repeat for the next band, as indicated by dashed line 420. The method 400 may be practiced with a field device coupled to a field device mount while the method 400 is being executed or may be coupled to a field device after the method 400 is completed.

[0059] Fig. 20 is a schematic diagram of a field device mount according to another embodiment of the present invention. The field device mount 500 includes a vertical tensioner assembly having a combination buckle tensioning mechanism 501, as described above. In this embodiment, the tensioning mechanism is a ratchet type device within the combination buckle tensioning mechanism. Using the buckle tensioning mechanism 501, the tension of the strap 104 is increased until a mark or appropriate indication of tension is displayed on the field device mount 500. The ratchet based embodiment will work well with large fluid handling equipment 101 including large piping systems, tanks, and irregularly shaped containers. The benefit of the ratchet type tensioning mechanism is that the field device mount has a built-in tensioning device, and no additional tensioning device is required to secure the strapping strap 104.

[0060] Fig.21 yes Fig. 20 An enlarged view of a field device according to an embodiment of the present invention is shown. In the example shown, the embodiment shows the engagement of a buckle tensioning mechanism 501 which is a combination buckle and ratchet type device in contact with the fluid handling equipment 101. The buckle tensioning mechanism 501 allows the installation of a field device mount 300 (not shown) without the need for a strap tensioning tool because it has a built-in ratchet function for tensioning the strap 104.

[0061] Fig. 22 FIG. 4 is a schematic diagram of a field device mounting socket according to another embodiment of the present invention. Fig. 22 Field device mount 300 is shown assembled to large fluid handling equipment 101 using a ratchet-type tensioning mechanism 501 .
