The invention belongs to the technical field of sensor test and particularly relates to a water temperature sensor test system. A control and acquisition center is used for judging whether pin-pair shell insulation resistance of a water temperature sensor connector assembly is qualified or not in a condition of 80-degree water temperature, judging whether a resistance value of a thermistor is qualified or not in a condition of 80-degree water temperature and in a condition of 110-degree water temperature, and judging whether a resistance value of an instrument resistor is qualified or not in a condition of 110-degree water temperature. According to the invention, a problem of a lack of a suitable water temperature sensor test system in the current market in the prior art is solved, and the technical effects of the water temperature sensor test system provided by the invention are that overall test ability of a water temperature sensor is improved; a circuit structure is characterized by simplicity and practicality; safety of the system is improved; and the water temperature sensor test system is improved.
Description
technical field [0001] The invention belongs to the technical field of sensor testing, in particular to a water temperature sensor testing system. Background technique [0002] The water temperature sensor is used to detect the temperature of the engine coolant, and has a negative thermistor element inside, which changes resistance as the temperature changes. The water temperature sensor function test equipment is to imitate the working environment of the product, soak the water temperature sensor in the water bath box, make the internal resistance change with the change of temperature, and then test the insulation resistance, thermistor and instrument of the product through the equipment Whether the resistance value is qualified can judge whether the product is qualified. The water temperature sensor function test system is a system used to test the function of the water temperature sensor. The water temperature sensor function test equipment is a device for the water tempe...
