Abstract

The application provides a sensor verification device and relates to the field of sensor testing. The device comprises a test environment generation module, a sensor comparison module, a sensor verification module and a central control module connected in series through a fluid pipeline. The central control module is configured to control the test environment generation module to dynamically change the test environment parameters according to a preset verification program, receive the reference measurement value sent by the sensor comparison module and the to-be-verified sensor measurement value sent by the sensor verification module, perform comprehensive verification on the performance of the to-be-verified sensor based on the comparison and analysis of the reference measurement value and the to-be-verified sensor measurement value, and output the comprehensive performance evaluation. The application can solve the technical problems of poor universality, low efficiency, incomplete verification and inability to simulate dynamic working conditions in the pre-production verification of sensors.
