  • Method and system for testing and calibrating gas sensors
    Patent number: 11579129
    Abstract: A system including one or more gas sensor assemblies having one or more gas sensors. The gas sensor is for sensing a preselected gas. The gas sensor assembly includes a housing with a cavity therein, and the sensor is mounted on the housing so that the sensor is able to detect the preselected gas in the cavity. The gas sensor assembly includes a sensor control module in communication with the gas sensor, and also in communication with a central controller. Via the central controller, the sensor may be tested using a purge gas, and the sensor may be zeroed if necessary. Also, via the central controller, the sensor may be calibrated using a calibration gas mixture having the preselected gas in a known concentration. The central controller is configured for manual or automatic testing and calibration. Accordingly, the testing and calibration, whether manual or automatic, is done remotely.
