Combustible gas refers to a gas that can be evenly mixed with air within a certain concentration range to form a premixed gas, which will explode when encountering a fire source, and release a lot of energy during the combustion process. The combustible gas detector is the 1 kind of special gas detector used to detect combustible gas. It can monitor the concentration of combustible gas in the environment in real time. Once it exceeds the safety threshold, it will immediately issue an alarm to effectively prevent fires and explosions. The occurrence of safety accidents. Do you know the common causes of alarms for combustible gas detector ? The following is a brief introduction by Yiyuntian:

1. gas concentration exceeded

Cause: this is the most common cause of combustible gas detector alarm. When the concentration of combustible gas in the environment exceeds the alarm threshold set by the detector, the instrument will immediately issue an alarm. These combustible gases may include natural gas, liquefied gas, methane, acetylene, etc.

: Immediately confirm whether there is a combustible gas leak and find the source of the leak. Quickly take emergency measures, such as closing the gas source, ventilation, etc., to reduce the concentration of combustible gas. Notify relevant personnel to evacuate the site and ensure personnel safety.

2. Tester failure

Reason: the combustible gas detector itself may malfunction, causing false alarms or not working properly.This may be due to aging of the sensor, circuit damage, battery exhaustion, etc.

Countermeasures: Maintain and calibrate the tester regularly to ensure it is in good working condition. If you suspect that the detector is faulty, you should promptly contact professionals for maintenance or replacement. Before confirming the failure of the detector, do not ignore the alarm signal, so as not to miss the real danger.

3. environmental interference

Reason: certain environmental factors, such as temperature, humidity, electromagnetic interference, etc., may affect the normal operation of the combustible gas detector and cause false alarms. For example, a high temperature or high humidity environment may cause the performance of the sensor to be degraded, and electromagnetic interference may affect the signal transmission of the detector.

: When installing the tester, try to avoid placing it in a location that is susceptible to environmental interference. Regularly test the environmental adaptability of the detector to ensure that it can work normally in various environments.If it is found that environmental interference leads to false alarm, the setting of the detector should be adjusted in time or other measures should be taken to eliminate the interference.

4. alarm values are not set properly
