AI Technical Summary
Technical Problem
The traditional contactless capacitive level sensor life test method cannot simulate the real liquid medium application environment and cannot detect liquid level deviation.
Method used
A contactless capacitive liquid level sensor life test equipment including a test box and a control device is designed. The test box is divided into a liquid storage area and a sensor test area through a partition. The brushless DC water pump and float level switch are used to simulate liquid level changes and realize cyclic testing.
Benefits of technology
It realizes the simulation of the actual liquid medium usage environment, can accumulate the number of life tests, adjust the single cycle cycle, and is cheap.
