Problems solved by technology

When calibrating each current sensor, it needs to go from 0A to 60A and then to 0A, and reversely from 0A to 60A and then to 0A. It is realized by manually adjusting the current source, which has low efficiency, high time cost and labor cost.

The device is high in test efficiency, high in test precision, high in automatic degree, good in safety and capable of measuring linearity, response time, measurement frequency and other parameters simultaneously.

Description

technical field [0001] The invention belongs to the field of detection devices for automobile sensing components, in particular to a detection device for automobile current sensors. Background technique [0002] With the development of automobile technology towards integration and intelligence, automobile manufacturers and users have put forward more and more stringent requirements for sensors. As a basic and necessary vehicle sensor, current sensor plays a very important role in the field of modern automobile industry. Each car is equipped with several current sensors, which are used to detect the current of various parts of the vehicle, provide data for the vehicle ECU, and judge the state of the vehicle. [0003] The current sensor needs to calibrate the zero point, full scale, gain and other parameters during production, and the test accuracy and other parameters of the sensor need to be tested before leaving the factory. The production and testing of the traditional me...
