What is an Infrared Flammable Gas Detector?

Infrared flammable gas detector is an efficient detection tool using infrared technology, mainly used to accurately measure gas concentration. It works based on the specific absorption spectrum of infrared rays by different gases, and judges the presence of harmful gases by analyzing the absorption characteristics of these gases. When the gas flows through the detector, part of the infrared rays will be absorbed by the gas molecules, resulting in a decrease in the intensity of the infrared rays received by the detector. Subsequently, the thermal effect generated by these gas molecules when absorbing and radiating infrared rays will cause the thermocouple to generate an electric potential difference, which will eventually be converted into an electrical signal output.

Infrared flammable gas detectors are highly favored for their fast detection speed, high measurement accuracy, rapid response, strong stability and strong anti-interference ability. It is particularly worth mentioning that it has extremely high sensitivity to low molecular weight organic matter. However, this detector is sensitive to changes in gas temperature and humidity, and due to the limited absorption capacity of different gases for infrared rays, it has certain limitations in identifying gas types.

Infrared flammable gas detectors are widely used in many industries, including petroleum, chemical, metallurgy, electricity and natural gas, etc., for monitoring gas concentrations in these industries. In addition, infrared flammable gas detectors also play an important role in the field of gas safety monitoring and fire monitoring in buildings. Its fast response and high accuracy make it an indispensable part of the fire detection system.
