The function of a combustible gas alarm is to detect the concentration ratio of combustible gases in a certain unit of air. When the concentration of combustible gases reaches a certain value, the alarm will sound,avoidDue to gas leakage causing losses,withlike thisThe way toEnsure the safety of enterprise production and people's lives. Combustible gas alarmEquipment commonly used forchemical enterprise，Huiruipu Electronics has summarized some issues that are easily overlooked by users in daily use.Details are as follows:
1、Using a combustible gas alarm in an oxygen deficient atmospheric environment may result in readings of combustible gases that are lower than the actual concentration. Conversely, using a combustible gas alarm in an oxygen rich environment may result in readings of combustible gases that are higher than the actual concentration.
2、When the concentration of combustible gas is reported, causing the instrument to display "out of range", the combustible gas sensor needs to be recalibrated. If the range of the combustible gas alarm is 0-LEL during use, and the actual concentration is higher than it, it will cause the phenomenon of exceeding the range. At this time, it is necessary to recalibrate the gas sensor.
3、Water vapor of silicone compounds or other known substancesimpurityIt may affect the normal operation of the combustible gas sensor, causing its reading to be lower than the actual gas concentration. If the instrument has been used in the water vapor environment of silicone compounds, to ensure accurate measurement, please recalibrate the instrument before the next use.
