[0013] 1. This device achieves a tight fit with the pressure sensor through the cooperation of a ring-shaped metal sleeve and an anti-slip rubber pad. Combined with the mounting ears, the entire device can be quickly fixed without modifying the sensor itself. It is easy to install and avoids the cumbersome operation of traditional separate temperature monitoring equipment that requires additional wiring. The temperature monitoring component is detachably connected to the ring-shaped metal sleeve by a buckle, and the signal conversion component is fixed between the mounting ears by an arc-shaped metal bracket.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a pressure sensor temperature monitoring device, including an annular metal sleeve 1, which is used to cover the outer surface of the pressure sensor. The inner wall of the annular metal sleeve 1 is provided with anti-slip rubber pads 2. Mounting ears 3 are symmetrically arranged on the outer circumference of the annular metal sleeve 1. The annular metal sleeve 1 is provided with a temperature monitoring component 4 for acquiring temperature signals and a signal conversion component 5 for processing and transmitting temperature signals. The anti-slip rubber pads 2 are continuously distributed along the inner circumference of the annular metal sleeve 1. The mounting ears 3 are integrally formed with the annular metal sleeve 1. The temperature monitoring component 4 is fixed to the annular metal sleeve 1 by a detachable structure. The outer circumference of the annular metal sleeve 1 and the inner side of the anti-slip rubber pad 2 are provided with continuously distributed anti-slip textures, and the anti-slip textures are intersecting diamond-shaped convex patterns. The annular metal sleeve 1 serves as the main frame of the device. The anti-slip rubber pad 2 on its inner side increases the friction with the outer surface of the pressure sensor through the intersecting diamond-shaped convex patterns. This not only ensures a tight fit to prevent loosening, but also buffers slight vibrations during installation and use. With the symmetrical mounting ears 3 on the outer circumference of the annular metal sleeve 1, the entire device can be quickly fixed to the equipment panel or bracket through the mounting holes. This ensures that the relative position of the device and the sensor is always reliable in terms of both installation stability and convenience.

[0022] like Figure 3 As shown, the temperature monitoring component 4 includes a buckle 401 that engages with the annular metal sleeve 1, a fixing base 402 fixed to the top of the buckle 401, a temperature probe 403 embedded inside the fixing base 402, and a wire 404 connecting the temperature probe 403. The buckle 401 is an annular structure with an opening, and its inner sidewall has an arc-shaped surface that fits the outer circumference of the annular metal sleeve 1. An insulating ceramic sleeve 405 is fitted around the temperature sensing end of the temperature probe 403. One end of the insulating ceramic sleeve 405 is flush with the end face of the fixing base 402, and the other end is along the edge of the temperature probe. The axial extension of 403 and the snap-fit ​​401 of the temperature monitoring component 4, with its open annular structure and inner arc surface, can easily engage with the annular metal sleeve 1 and be tightened with bolts, enabling quick assembly and disassembly of the component for later maintenance and replacement. The fixing seat 402 plays a precise positioning role for the temperature probe 403, while the insulating ceramic sleeve 405 on the outside of the temperature sensing end can not only isolate external electromagnetic interference and dust and moisture, preventing the temperature probe 403 from being affected by the environment and causing monitoring deviation, but also prevent the probe from contacting the metal parts and short-circuiting, ensuring the accuracy and safety of temperature acquisition.

[0023] like Figure 4As shown, the signal conversion assembly 5 includes an arc-shaped metal bracket 501, which is fixedly installed between two sets of mounting ears 3. Two sets of L-shaped fixing brackets 502 are fixedly installed on the outer side of the arc-shaped metal bracket 501. A signal conversion box 503 is fixedly installed on the L-shaped fixing brackets 502. A signal conversion circuit is provided inside the signal conversion box 503. A strip-shaped metal terminal block 504 is provided on the top of the signal conversion box 503. An interface 505 is provided on the outer wall of the signal conversion box 503. One side of the strip-shaped metal terminal block 504 is connected to the signal conversion circuit through a wire. The arc-shaped metal bracket 501 of the signal conversion assembly 5 matches the curvature of the annular metal sleeve 1. After being fixed between the two sets of mounting ears 3, it can form a stable support structure. The two sets of L-shaped fixing brackets 502 on its outer side are fixed by welding and bolts to firmly support the signal conversion box 503, so that the signal conversion box 503 is not easily displaced due to vibration during the operation of the device, providing a stable installation environment for the internal circuit and external connection components.

[0024] like Figure 2 As shown, one end of the wire 404 is connected to the temperature probe 403, and the other end passes through the signal adapter box 503. The wire 404 is a multi-strand copper core high-temperature resistant wire, and its outer layer is wrapped with a fluoroplastic insulation layer. The interfaces 505 are a power port for connecting to an external DC power supply, a temperature signal output port for connecting to a display device, and a sensor signal port for connecting to the signal terminal of a pressure sensor. The signal conversion circuit inside the signal adapter box 503 can convert the analog temperature signal transmitted by the temperature probe 403 through the wire 404 into a digital signal. The strip-shaped metal terminal block 504 on the top enables quick plugging and unplugging of the wire 404 and the circuit through neat wiring terminals, which is convenient for circuit maintenance. The interface 505 on the outer wall integrates power supply, temperature output, sensor signal and other functional ports. It can not only connect to an external DC power supply to power the device, but also transmit the processed temperature data to the display device, and receive pressure sensor signals to realize the coordinated transmission of temperature and pressure signals, thereby improving the integration of data interaction.

[0025] The working principle of this utility model is as follows: First, an annular metal sleeve 1 is fitted onto the outer surface of the pressure sensor. The anti-slip rubber pad 2 on the inner side enhances the stability of the fit with the sensor with the help of diamond-shaped ridges. Then, the whole is fixed by the mounting ear 3. The temperature monitoring component 4 is fixed on the annular metal sleeve 1 by the buckle 401. The temperature sensing end of its temperature probe 403 is in close contact with the sensor shell under the protection of the insulating ceramic sleeve 405. The temperature signal is collected in real time and transmitted to the signal conversion component 5 through the multi-strand copper core high-temperature resistant wire 404. In the signal conversion component 5, the signal conversion box 503 supported by the arc-shaped metal bracket 501 and the L-shaped fixing bracket 502 processes the received temperature signal through the internal signal conversion circuit. The strip metal terminal block 504 connects the wire 404 to the circuit. Then, the power port of the interface 505 is connected to the external power supply, and the temperature signal output port is transmitted to the display device. At the same time, the pressure sensor signal is received through the sensor signal port to realize the coordinated processing of temperature and pressure signals. Finally, the accurate temperature monitoring and data output of the pressure sensor are completed. At this point, the whole process is completed.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
