Description

Technical Field

[0001] This invention belongs to the field of temperature sensor performance testing technology, and in particular relates to a reconfigurable temperature sensor thermal response time testing system. Background Technology

[0002] The thermal response time of a temperature sensor is a core indicator for measuring its dynamic temperature measurement performance. It directly determines the sensor's temperature measurement accuracy and real-time performance in scenarios with rapid temperature changes, and is a mandatory test item for sensor factory testing and performance calibration.

[0003] Existing temperature sensor thermal response time testing devices generally adopt an integrated structure of the thermostatic bath and testing equipment, using two thermostatic baths to provide the test medium and temperature environment. This structure has the following drawbacks:

[0004] 1. The process of changing the test medium is cumbersome: When it is necessary to conduct comparative tests in different media such as water, oil, and air, the original medium must be drained first, and the inner cavity of the constant temperature bath must be repeatedly cleaned, cleaned, and dried before the new medium can be injected. The whole process is time-consuming and complicated.

[0005] 2. High risk of cross-contamination of media: Incomplete cleaning can easily lead to the mixing of different media residues, which can change the thermal conductivity of the media and directly reduce the accuracy and repeatability of thermal response time tests.

[0006] 3. Low testing efficiency: The media replacement and constant temperature bath pretreatment take up a lot of time, making it impossible to quickly switch between high and low temperatures and different media environments, which makes it difficult to meet the high-efficiency detection requirements of batch sensors.

[0007] 4. Poor device versatility: The single-tank integrated structure cannot flexibly adapt to testing scenarios with multiple temperature points and multiple media, and the device lacks reconfigurability and expandability.

[0008] To address the aforementioned issues, existing technologies lack simple and efficient solutions, severely limiting the convenience, accuracy, and efficiency of temperature sensor thermal response time testing. Summary of the Invention

[0054] In another embodiment of the present invention, an alarm light 19 is fixedly connected to the top of the body 1. The alarm light 19 is electrically connected to the human-machine interface 12 and triggers an audible and visual alarm when the temperature is abnormal or the mechanism malfunctions.

[0055] This system also features a "liquid thermal shock cycle test" function, specifically designed for this type of test, as per national standard "GB / T2423.22-2012". It can perform liquid thermal shock tests, reducing equipment investment costs and floor space, achieving dual functionality in one machine. (The constant temperature bath uses a PT100 platinum resistance thermometer + a Japanese-imported precision temperature controller with PID automatic temperature control. Low temperature bath: temperature range -30℃~+40℃, accuracy 0.01℃; High temperature bath: temperature range +50℃~+300℃, accuracy 0.03℃).

[0056] The thermal response time test procedure for this system is as follows:

[0057] Thermal response time testing standard: based on national standard "GB / T 6663.1-2007"

[0058] The formula for calculating Ti in thermal response time testing is: Ti = Ta + (Tb - Ta) * 63.2%

[0059] Ti = Thermal response time (63.92℃) Ta = 25℃ Tb = 85℃

[0060] Thermal response time: The time required for the zero-power resistance value at temperature Ta to reach the zero-power resistance value at temperature Ti is equal to the time from 25℃ to 62.92℃.

[0061] 1. Input the corresponding resistance values ​​at Ta and Ti temperatures into the low-temperature resistor 2 and high-temperature resistor 3 respectively in advance, select the corresponding liquid medium according to the test conditions, and set the temperature;

[0062] 2. Then manually load the object to be tested into the "clamping position 6" on the Z-axis moving mechanism, and then connect the object to be tested to the testing system;

[0063] 3. Press the device start button, and the Z-axis lifting component 4 will descend, immersing the object to be tested into the liquid in the "first constant temperature bath 7" (the temperature of the first constant temperature bath 7 is 5℃ lower than that of Ta, so that the object to be tested will not be affected when moving). After the resistance value of the object to be tested stabilizes, the Z-axis lifting component 4 will rise to the origin.

[0064] 4. The moving component 5 moves to the right above the "second constant temperature bath 8", and the Z-axis lifting component 4 descends, immersing the test object in the liquid of the "second constant temperature bath 8". The system automatically prepares for timing detection. When the resistance value detected by the test system is consistent with the resistance value set by the "low temperature resistor 2" (i.e., the resistance value corresponding to the Ta temperature point), the PLC is triggered to start timing. When the resistance value set by the "high temperature resistor 3" is reached, the system automatically triggers the PLC to stop timing. The results will be displayed on the "human-machine interface 12" and the "time display 11" (the test results are obtained in the same constant temperature bath, eliminating test errors caused by any other factors).

[0065] 5. After obtaining the test results, the Z-axis lifting component 4 rises to the origin, and the moving component 5 moves to the left back to the origin, thus ending the entire test process.

[0066] The liquid thermal shock cycle test procedure for this system is as follows:

[0067] 1. In the "Liquid Thermal Shock Cyclic Test" mode, pre-set the cyclic temperature, cyclic time, and number of cycles according to the test conditions;

[0068] 2. Then manually load the object to be tested into the "clamping position 6" of the Z-axis moving mechanism, and then press the equipment start switch 16 to start the test;

[0069] 3. The Z-axis lifting mechanism descends to the "first constant temperature bath 7 low temperature" so that the object to be tested is completely immersed in the liquid. After the cycle time is reached, the Z-axis lifting mechanism rises back to the origin.

[0070] 4. Move the moving component 5 to the right above the "second constant temperature bath 8 high temperature", and lower the Z-axis lifting component 4 to the "second constant temperature bath 8 high temperature" so that the object to be tested is completely immersed in the liquid. After the cycle time is reached, the Z-axis lifting component 4 rises to the origin.

[0071] 5. Move component 5 to the left above "First constant temperature bath 7 low temperature". This completes one cycle. After the set cycle is completed, the equipment will indicate completion and enter standby mode. The entire test process ends.

[0072] If it is necessary to stay at the ambient temperature during the high and low temperature cycle, it can be done while the moving component 5 is moving.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
