Sensor characteristic detecting and screening device

The invention relates to a detecting and screening device for sensor characteristics and the technical field of sensor applications and designs a detecting and screening device for characteristics ofan outside screw thread inductive sensor. A spiral transmission mechanism is used to realize the linear motion of an induction body in a test box, and the motion stability and the repeated position accuracy are higher. A rotating mechanism can penetrate the test box operation window and extend outside the test box to be manually operated by adopting a fixed extension structure, thereby achieving stable large-temperature-range action capability. The extension length of the screw is used as a measurement reference, the influence of the high and low temperature environment on a measuring tool isavoided, and the measurement accuracy is higher. A special quick mounting bracket is used as a mounting reference for the same type of the sensor, and the simultaneous reference, the rapid performancetesting and the screening
