The combustible gas alarm detector is a gas leak detection and alarm instrument. When a combustible gas leak occurs in an industrial environment, and the gas concentration reaches the critical point of explosion or the alarm setting, it will send an alarm signal to remind the staff to take safety measures, drive the exhaust, cut off, and spray systems to prevent Explosion, fire, and poisoning accidents occur to ensure safe production. So how to solve the false alarm of the combustible gas alarm?
1. False alarm of combustible gas alarm detector
Reason: the combustible gas alarm detector is aging
Solution: re-calibrate and replace with a new alarm.
2. The combustible gas alarm does not display on the display panel during use
Reason: The power supply voltage of the instrument is not normal, the display of the instrument may enter water, and the circuit board is faulty.
Solution: Check the insurance, check the line connecting the instrument. Clean the circuit board of the instrument and dry it. If it is determined to be damaged, replace the battery board and replace with a new instrument.
3. The combustible gas alarm shows that the concentration value is too large
Reason: When the alarm is calibrated, the concentration of the calibration gas does not meet the requirements, and the sensor is aging.
Solution: Use qualified calibration gas for calibration and replace with a new alarm
4. The combustible gas alarm shows a non-zero value under normal environment
Reason: The zero point of the alarm is drifting, the sensor guard may have residual combustible gas, and the sensor is aging.
Solution: Re-calibrate the zero point value in clean air, remove the sensor guard to clean up the dust, and replace with a new alarm.
The above are a few simple solutions for false alarms of combustible gas alarms. If the problem is not resolved, it is recommended that users contact the manufacturer of the alarm directly to prevent potential safety hazards.
