Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a combustible gas detection alarm. Background Art

[0002] The combustible gas detection alarm consists of a detector and an alarm control host. It is widely used in petroleum, gas, chemical, oil depot and other petrochemical industries where toxic gases exist. It is used to detect leaks in indoor and outdoor hazardous places. It is an important instrument to ensure production and personal safety. When toxic gas exists in the measured place, the detector converts the gas signal into a voltage signal or current signal and transmits it to the alarm instrument. The instrument displays the percentage concentration value of the lower explosion limit of the toxic gas. When the toxic gas concentration exceeds the alarm setting value, an audible and visual alarm signal will be generated. The on-duty personnel will take safety measures in time to avoid combustion and explosion accidents.
