How to Determine if the Sensor of the Flammable Gas Detector is Normal?

The flammable gas detector has a standard method to confirm the state of the sensor, as if it is to determine how much oil is in the fuel tank inside the car. It is called the retention value. The retention value is a measure of the sensitivity of the sensor and is derived when the gas detector is calibrated.

At the end of the gas detection calibration, the retained value of each sensor is displayed and stored in the instrument’s calibration record. When the sensor’s retention value is less than or equal to 50% of the calibration gas concentration, the sensor will fail to be calibrated and must be replaced.

When the retention value is between 50% and 70% of the calibration gas concentration, it indicates that the sensitivity of the sensor is at the edge state, and the replacement of the gas sensor can be considered at this time.

Simply say, when the flammable gas detector needs to be replaced, as long as the gas sensor has sufficient sensitivity or retention value to successfully calibrate, the flammable gas detector can be used normally. It is not necessary to replace the sensor until the sensor calibration fails.

Of course, the above is only the replacement cycle of our flammable gas detector under normal circumstances. It does not rule out some other faults in the flammable gas detector. If our flammable gas detector fails, it is recommended to contact the manufacturer in time. The manufacturer will according to your fault. The situation gives you the appropriate repair or replacement solution.
