[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1-3 As shown, this utility model discloses a temperature rise testing device for a high-temperature pressure measurement module, used for temperature testing of the high-temperature pressure measurement module. The high-temperature pressure measurement module is internally equipped with a temperature sensor and a heater, and the temperature sensor is electrically connected to the heater; it includes:

[0027] Support shell 1;

[0028] The detection component includes a temperature controller 2, an electrical controller 3, a signal transmission plug 4, and a heating plug 5. The temperature controller 2 is disposed on the side wall of the support shell 1, the electrical controller 3 is disposed inside the support shell 1, and the signal transmission plug 4 and the heating plug 5 are respectively disposed on the side wall of the support shell 1. The temperature controller 2 is electrically connected to the electrical controller 3 and the signal transmission plug 4, and the heating plug 5 is electrically connected to the electrical controller 3 and the high-temperature pressure measurement module. The signal transmission plug 4 is electrically connected to the high-temperature pressure measurement module.

[0029] The heater inside the high-temperature pressure measurement module is used to raise the temperature. When the heater is working, the temperature of the high-temperature pressure measurement module rises, and the temperature sensor detects the real-time value of the temperature rise. In this invention, the support shell 1 serves to install the entire detection assembly, providing mounting support for each component. The temperature controller 2 in the detection assembly controls the working state of the high-temperature pressure measurement module, thereby controlling the temperature of the module. The high-temperature pressure measurement module connects the temperature sensor to the temperature controller 2 via a signal transmission plug 4, enabling the transmission of the temperature sensor's detection signal; the high-temperature pressure measurement module connects to the electrical controller 3 via a heating plug 5, controlling the start and stop of the heater.

[0030] In the actual test, the two wiring harnesses of the high-temperature pressure measurement module were directly connected to the signal transmission plug 4 and the heating plug 5, respectively. First, the electrical controller 3 was turned on, and the heater inside the high-temperature pressure measurement module started working, causing the temperature to rise. The temperature sensor inside the high-temperature pressure measurement module fed back the real-time temperature of the high-temperature pressure measurement module to the temperature controller 2 through the signal transmission plug 4. When the heater reached the set temperature of the temperature controller 2, the temperature controller 2 controlled the electrical controller 3 to turn off. Similarly, when the temperature of the high-temperature pressure measurement module was lower than the set temperature of the temperature controller 2, the temperature sensor inside the high-temperature pressure measurement module fed back data to the temperature controller 2, and the temperature controller 2 controlled the electrical controller 3 to turn on, causing the heater to start working again and the temperature to rise again for testing.

[0031] This invention utilizes a temperature controller 2 to perform temperature testing on the high-temperature pressure measurement module. The testing procedure is simple and allows for direct testing of the high-temperature pressure measurement module at a very low cost, avoiding the risk of damaging the machine by directly testing it. This invention improves testing efficiency and reduces testing costs while simultaneously achieving temperature testing of the high-temperature pressure measurement module.

[0032] Furthermore, it also includes a circuit control assembly, which includes a first air switch 9, a second air switch 10, and a DC power converter 7. The first air switch 9, the second air switch 10, and the DC power converter 7 are disposed inside the support housing 1. The first air switch 9 is electrically connected to the temperature controller 2; the second air switch 10 is electrically connected to the electrical controller 3; and the DC power converter 7 is disposed between the first air switch 9 and the temperature controller 2.

[0033] Specifically, the circuit control components primarily function to power the entire device. The first air switch 9 and the second air switch 10 play a crucial role in short-circuit protection. The first air switch 9 is connected to the temperature controller 2, controlling its start and stop; the second air switch 10 is connected to the electrical controller 3, controlling the start and stop of the heater inside the high-temperature pressurization module. The DC power converter 7's main function is to convert the input AC power into DC power to suit the normal operation of the temperature controller. As a preferred embodiment of this invention, the DC power converter 7 is a 220V to 24V DC power supply, adapted to the normal voltage output of the temperature controller.

[0034] Furthermore, the circuit control assembly also includes a leakage current protector 8, which is disposed inside the support housing 1 and is electrically connected to the first air switch 9 and the second air switch 10 respectively.

[0035] Specifically, the main function of the residual current device (RCD) 8 is to prevent equipment leakage and electric shock, protecting the electrical safety of homes and industries. When electrical equipment experiences leakage, the RCD 8 can quickly cut off the power supply to prevent electric shock accidents. Its working principle is to detect the residual current in the circuit; when an abnormal current is detected, the RCD 8 will quickly cut off the power supply, thereby protecting the circuit.

[0036] Furthermore, a fuse 6 is also connected between the leakage current protector and the first air switch 9 and the second air switch 10.

[0037] Specifically, the function of fuse 6 is to improve the safety of the entire test device circuit system. Its working principle is as follows: when the current exceeds the specified value, the heat generated by the fuse itself causes the fusible element to melt, thus breaking the circuit. It is an electrical device that, based on the principle that after the current exceeds the specified value for a period of time, the heat generated by the fuse itself melts the fusible element, thereby breaking the circuit and ensuring the stability of the entire circuit system.

[0038] In actual testing, the high-temperature pressure measurement module may contain multiple temperature sensors and heaters. As a preferred embodiment of this invention, the temperature controller 2 has four units, adaptable to different types of high-temperature pressure measurement modules for temperature testing.

[0039] Furthermore, as a preferred embodiment of this utility model, the electrical controller 3 is a solid-state relay, which has high reliability, low electromagnetic interference, fast switching, and strong anti-interference capability. The number of solid-state relays corresponds to the number of temperature controllers 2, and is used to control the start and stop of the corresponding heaters.

[0040] Furthermore, as a preferred embodiment of this utility model, the signal transmission plug 4 is a DB25 plug, which has the advantages of multi-channel transmission and high connection reliability. Specifically, the DB25 plug has 25 connecting pins inside, which can connect multiple temperature sensors to transmit signals to the corresponding temperature controller 2, and the wiring terminals of the signal transmission plug 4 extend into the support shell 1.

[0041] Furthermore, the heating plug 5 is an aviation plug, and the wiring end of the aviation plug extends into the interior of the support shell 1.

[0042] Similarly, the aviation plug also has good reliability, environmental resistance and versatility, and can connect multiple heaters and control the start and stop of multiple heaters through multiple electrical controllers 3.

[0043] Furthermore, the temperature controller 2 is provided with a display screen 21, and the side of the temperature controller 2 with the display screen 21 faces the outside of the support shell 1.

[0044] Specifically, the temperature controller 2 in this utility model includes a display screen 21, which provides feedback on the real-time temperature of the high-temperature pressure measuring module.

[0045] In summary, this utility model introduces a temperature rise testing device for a high-temperature pressure measurement module. The specific testing steps are as follows: Before testing, connect the two wiring harnesses of the high-temperature pressure measurement module to the signal transmission plug 4 and the heating plug 5 respectively. First, turn on the electrical controller 3, the heater starts working, and the temperature of the high-temperature pressure measurement module rises. The temperature sensor inside the high-temperature pressure measurement module feeds back the real-time temperature of the high-temperature pressure measurement module to the temperature controller 2 through the signal transmission plug 4. When the heater heats up to the set temperature of the temperature controller 2, the temperature controller 2 controls the electrical controller 3 to turn off. Similarly, when the temperature of the high-temperature pressure measurement module is lower than the set temperature of the temperature controller 2, the temperature sensor inside the high-temperature pressure measurement module feeds back data to the temperature controller 2, the temperature controller 2 controls the electrical controller 3 to turn on, so that the heater starts working again, and the temperature rises again for testing.

[0046] This invention utilizes a temperature controller 2 to perform temperature testing on a high-temperature pressure measurement module. The testing procedure is simple and allows for direct testing of the module's functionality at a minimal cost, avoiding the risk of damaging the machine by directly testing it with other equipment. This invention not only achieves temperature testing of the high-temperature pressure measurement module but also improves testing efficiency and reduces testing costs.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
