Description

Technical Field

[0001] The utility model relates to the technical field of sensor testing, in particular to a testing device for humidity sensor production. Background Art

[0002] At present, sensors are widely used in various fields. Sensors are a kind of detection device, which mainly transmits, displays, stores, and records the sensed information. Due to their wide application fields, there are many types of sensors. Among them, humidity sensors are mainly sensors that convert the sensed humidity into output signals.

[0003] For example, patent document CN214224449U discloses a test device for humidity sensor production, comprising a device body, with height adjustment mechanisms provided on both sides of the top of the device body. This device for humidity sensor production comprises a fixed plate, a support plate, an adjustment knob, a clamping plate, and a limit bolt. Before testing, the fixed plate is higher than the device body, making it easier for workers to clamp and limit the humidity sensor. The humidity sensor is placed directly above the fixed plate, and the distance between the clamping plates is adjusted according to the specifications of the humidity sensor. The length of the limit bolt is adjusted by turning the adjustment knob clockwise. The limit bolt and the clamping plate are fixedly connected, thereby reducing the distance between the clamping plates, so that the clamping plates are clamped on both sides of the humidity sensor to prevent sliding during testing, thereby ensuring the accuracy of the sensor test. This solves the problem of inconvenience in clamping and fixing the sensor, which is prone to movement during testing, affecting test accuracy. The above device only tests the waterproof performance of the humidity sensor. The detection accuracy and working condition of the humidity sensor at different temperatures are also important test items. In addition, the clamping mechanism of the above device cannot allow the humidity sensor to be clamped quickly, affecting work efficiency. Utility Model Content
