In short, a combustible gas alarm is a device that detects the lower limit of gas explosion. To ensure its long-term safety, reliability, and efficient operation, sufficient attention must be paid, because the failure of the combustible gas alarm may lead to a large amount of leakage of toxic and combustible gases, not only causing explosion and fire accidents, but also posing a threat to the life safety of employees. So what are the reasons for the malfunction of the combustible gas alarm?
1, Emphasize the selection of equipment
The sensing element is the heart of an instrument and plays a decisive role in its sensitivity, repeatability, linearity, and lifespan. The response sensitivity of various gases varies on different instruments. Fully considering the cost-effectiveness of the equipment and choosing equipment with stable performance as much as possible will provide reliable assurance for normal operation in the later stage.
2, Place of use of equipment
1. The impact of natural environment on the performance of equipment placement location
2. The influence of electromagnetic waves on the performance of combustible gas alarms
(1) Airborne electromagnetic interference
For example, there is a certain distance between the combustible gas alarm and the alarm system, which is usually located in the monitoring and dispatching room of the oil transportation station. In our daily detection work, we usually need to use explosion-proof wireless walkie talkies for dialogue. If the distance between the walkie talkie and the combustible gas alarm is too close during the intercom process, the combustible gas alarm cannot function properly.
(2) Narrow pulse group on power supply and other input/output lines
(3) Human static electricity
The reasons for the malfunction of the combustible gas alarm mentioned above are shared here. Various problems encountered during the use of the combustible gas alarm cannot be ignored, as any small problem in our eyes can lead to fatal tragedies. Therefore, when purchasing a combustible gas alarm, it is important to choose a combustible gas alarm manufacturer with comprehensive after-sales service.
