Description

technical field

[0001] The invention belongs to the technical field of measuring physical parameters of products, in particular to a high-efficiency high-voltage sensor testing machine for performance testing of sensors. Background technique

[0002] At present, the existing sensor-specific detection equipment can realize sine wave servo control, and its shortcoming is mainly a single waveform. However, the existing combined equipment for sensor-specific detection can realize quasi-sine wave servo control. The main disadvantage is that it is a quasi-sine wave. The combination device is a combination of multiple devices, and the equipment is complicated. Recently foreign relevant materials report that there is a special device that can realize the servo control of multiple waveforms, but the detection steps are complicated, the equipment is expensive, and the detection cost is high. To sum up, the characteristics of the existing sensor-specific detection equipment are: appli...
