Natural gas is a fossil fuel mainly composed of alkanes, of which methane accounts for 70% to 90% of its composition, with small amounts of ethane, propane and butane. Methane is a colorless, odorless and flammable gas, which is prone to gas leakage during production, storage, transportation, distribution and use, and it is easy to cause fire, explosion and other serious safety accidents after leakage.

 

 

In modern technology, the detection of natural gas leakage is mainly divided into the detection of methane gas and the detection of natural gas pipelines. Methane detection is widely used in both industrial and civil fields. The methane sensor used in the detection can monitor the status of the gas in real time and inform the user at the first time after a leak occurs.

 

 

Daoheshun Sensor has been focusing on sensor technology innovation to provide users with top-performing gas sensing technology and products. A few days ago, Daohe Shun Sensor's new NDIR dual-channel civil infrared methane sensor DSH01M-M50K-JS has been officially launched, using technology to help defend the "last pass" of gas safety and escort our life and property safety.

 

1. Product description

 

 

DSH01M-M50K-JS is a high-performance infrared methane gas sensor based on NDIR infrared absorption detection principle. The product uses a single light source and a double channel detector to realize a double optical path reference compensation. The microprocessor is used to collect, process and output the signal, the ambient temperature compensation is realized, the nonlinear relation in principle is corrected, and the signal has various output forms. It can be widely used in gas alarms, environmental detection, robots, intelligent buildings, smart kitchens and other civil and quasi-industrial occasions.
