[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an integrated sealed pressure transmitter structure, including: a housing 1, an interface block 2 installed at one end of the housing 1, an installation block 3 welded to one end of the inner wall of the housing 1, a sealing sheet 4 installed on one side of the installation block 3, an installation plate 5 installed on the inner wall of the housing 1, a pressure sensitive element body 6 installed on one side of the installation plate 5, and a Hirschmann joint 8 connected to the other end of the housing 1 via a flange.

[0023] Specifically: When the device is first used, the mounting plate 5, on which the pressure-sensitive element body 6 is installed, is mounted on the mounting block 3 welded to one end of the inner wall of the outer shell 1. The sealing plate 4 installed on one side of the mounting block 3 provides a better sealing effect for the installation of the pressure-sensitive element body 6, preventing moisture from entering the inner wall of the device and making the device more perfect.

[0024] In one embodiment, a limiting block 501 is installed at equal intervals around the surface of the mounting plate 5, and a limiting groove 101 is opened at equal intervals around the inner wall of one end of the outer casing 1. The surface of the limiting block 501 is movably mounted on the inner wall of the limiting groove 101.

[0025] Specifically: The surface of the limiting block 501, which is installed at equal intervals around the circumference of the mounting plate 5, is mounted on the inner wall of the limiting groove 101 opened at one end of the inner wall of the outer shell 1, so that the mounting plate 5 is installed inside the outer shell 1 more smoothly, the installation effect is better, and the device is more perfect.

[0026] In one embodiment, bolts 7 are threaded at equal intervals around the surface of the mounting plate 5, and the surface of the bolts 7 passes through the sealing plate 4 and is threaded into the interior of the mounting block 3.

[0027] Specifically: After the mounting plate 5 is installed on the inner wall of the outer shell 1, the bolts 7, which are threaded at equal intervals around the circumference of the mounting plate 5, pass through the sealing sheet 4 and are threaded into the inner wall of the mounting block 3. Then, by tightening the bolts 7, the mounting plate 5 compresses the sealing sheet 4, so that the mounting plate 5 and the mounting block 3 have a better sealing effect, effectively preventing water vapor from entering the interior of the device and making the device more perfect.

[0028] In one embodiment, a threaded groove 102 is provided on the inner wall of one end of the outer casing 1, and a threaded block 201 is installed on one end of the interface block 2, with the surface threads of the threaded block 201 embedded in the inner wall of the threaded groove 102.

[0029] Specifically: The threaded surface of the threaded block 201 installed at one end of the interface block 2 is embedded in the inner wall of the threaded groove 102 opened at one end of the inner wall of the outer shell 1, so that the interface block 2 can be stably installed at one end of the outer shell 1, making the device more complete.

[0030] In one embodiment, an mounting shell 9 is installed on the inner wall of the outer shell 1, a friction plate 901 is installed on the inner wall of the mounting shell 9, a signal conditioning circuit 10 is installed on the inner wall of the mounting shell 9, a conversion module 11 is installed at the other end of the inner wall of the outer shell 1, one side of the conversion module 11 is connected to the Hirschmann connector 8, a second limiting block 1101 is installed at equal intervals around the surface of the conversion module 11, a second limiting groove 103 is opened at equal intervals around the other end of the inner wall of the outer shell 1, and the surface of the second limiting block 1101 is embedded in the inner wall of the second limiting groove 103.

[0031] Specifically: By installing the signal conditioning circuit 10 in the inner wall of the mounting shell 9 installed on the inner wall of the outer shell 1, and increasing the friction between the surface of the signal conditioning circuit 10 and the inner wall of the mounting shell 9 by the friction plate 901 installed on the inner wall of the mounting shell 9, the signal conditioning circuit 10 can be stably installed inside the device. The surface of the limiting block 1101 installed at equal intervals around the surface of the conversion module 11 is installed in the inner wall of the limiting groove 103 opened at equal intervals around the inner circumference of the other end of the outer shell 1. One side of the conversion module 11 is connected to the Hirschmann connector 8 installed at the other end of the outer shell 1, so that the conversion module 11 can be stably installed inside the device, thereby making the components inside the device stably installed inside the device, making the device more complete.

[0032] In one embodiment, the pressure-sensitive element body 6 and the signal conditioning circuit 10 are connected by a connecting line, and the signal conditioning circuit 10 and the conversion module 11 are connected by a connecting line.

[0033] Specifically: The pressure-sensitive element body 6 and the signal conditioning circuit 10 are connected by a connecting line. The signal conditioning circuit 10 and the conversion module 11 are also connected by a connecting line. When the device is in use, the liquid enters through the interface block 2 installed at one end of the outer shell 1 and comes into contact with the pressure-sensitive element body 6, converting the pressure signal into a weak electrical signal. This signal is then transmitted to the signal conditioning circuit 10 through the connecting line. The signal conditioning circuit 10 amplifies, filters, and performs temperature compensation processing on the weak signal. The processed signal is then transmitted to the conversion module 11 through the connecting line. The conversion module 11 converts the electrical signal into a digital signal, which is then sent to the microprocessor inside the Hirschmann connector 8 for calculation and correction before being output, thus improving the device.

[0034] Working Principle: When the device is first used, the pressure-sensitive element body 6 and the signal conditioning circuit 10 are connected by a connecting line. The signal conditioning circuit 10 and the conversion module 11 are also connected by a connecting line. During use, liquid enters through the interface block 2 installed at one end of the outer casing 1 and comes into contact with the pressure-sensitive element body 6, converting the pressure signal into a weak electrical signal. This signal is then transmitted to the signal conditioning circuit 10 via the connecting line. The signal conditioning circuit 10 amplifies, filters, and performs temperature compensation processing on the weak signal. The processed signal is then transmitted to the conversion module 11 via the connecting line. The conversion module 11 converts the electrical signal into a digital signal, which is then sent to the microprocessor inside the Hirschmann connector 8 for calculation and correction before output. The limiting block 501 installed on the surface of the mounting plate 5 is installed on the inner wall of the limiting groove 101, so that the bottom of the mounting plate 5 is attached to the sealing plate 4 installed on one side of the mounting block 3. Then, the bolt 7 is screwed into the inner wall of the mounting plate 5, passes through the sealing plate 4, and screws into the mounting plate 5. Inside the mounting block 3, tightening the mounting plate 5 compresses the sealing sheet 4, resulting in a better seal between the mounting plate 5 and the mounting block 3. This effectively prevents moisture from entering the device and protects it from moisture, making the device more complete. By installing the signal conditioning circuit 10 inside the mounting shell 9 mounted on the inner wall of the outer shell 1, and increasing the friction between the surface of the signal conditioning circuit 10 and the inner wall of the mounting shell 9 using the friction plate 901 mounted on the inner wall of the mounting shell 9, the signal conditioning circuit 10 can be stably installed inside the device. The surface of the limiting block 1101, which is equidistantly mounted on the surface of the conversion module 11, is installed in the inner wall of the limiting groove 103, which is equidistantly opened on the inner circumference of the other end of the outer shell 1. One side of the conversion module 11 is connected to the Hirschmann connector 8 mounted on the other end of the outer shell 1, allowing the conversion module 11 to be stably installed inside the device. This ensures that the components inside the device are stably installed, making the device more complete.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
