In order to effectively prevent explosions, fires, and poisoning accidents and ensure safe production, it is currently required to install combustible gas alarms. Its gas alarm is the 1 kind of gas leakage detection and alarm instrument. When combustible gas leakage occurs in industrial environment, when the combustible gas alarm detects that the gas concentration reaches the critical point of explosion or the alarm setting, it will send out an alarm signal to remind the staff to take safety measures. However, during the use of combustible gas alarm , we will inevitably encounter some malfunctions.

combustible gas alarm common faults and solutions:

1. the false alarm of the combustible gas alarm

>

Reason: combustible gas alarm aging .

Solution: Re-calibrate and replace the alarm with a new one.

2. combustible gas alarm display panel does not display during use

Reasons: the power supply voltage of the instrument is abnormal, the display screen of the instrument may be flooded, and the circuit board is faulty .

Solution: Check the safety and the wiring connecting the instrument. Clean the instrument circuit board and dry it. After determining the damage, replace the battery board and replace the new instrument.

3. combustible gas alarm shows a large concentration value

reason: when the combustible gas alarm is calibrated, the standard gas concentration does not meet the requirements, and the sensor is aging.

Solution: Use qualified standard gas for calibration and replace with a new combustible gas alarm.

4. combustible gas alarm does not indicate 0 in normal environment

Solution: Re-calibrate the zero value under clean air, disassemble the sensor shield to clean up dust, and replace it with a new combustible gas alarm.

To sum up, it is the common fault and solution of combustible gas alarm. When we encounter some minor faults in the combustible gas alarm, we must pay attention to check the cause and analyze it, so as to solve the root cause. Only in this way can it be better to ensure that the combustible gas alarm can be used normally.
