Gas sensor failure detection device, gas sensor failure detection system, and gas sensor failure detection method

摘要

The gas sensor failure detection device is a gas sensor failure detection device for a gas leak inspection device that detects gas filled in the inspection object from the outside of the inspection object and detects gas leakage of the inspection object, A gas ejection unit 22 that ejects gas toward the detection range of the gas sensor, and a position fixing unit 21 that fixes the position of the gas ejection unit 22 to an assumed gas leak position in the inspection object are provided.
