What is the detection standard range of combustible gas alarm?
"LEL" refers to the lower explosive limit, which is a technical term for combustible gas. The low concentration of combustible gas that will explode when encountering open flame in the air is called the lower explosion limit, or "LEL" for short. English: Lower Explorative Limit. When the concentration of combustible gas in the air reaches its lower explosion limit, we call the explosion risk of combustible gas environment in this place 100% LEL. Next, let's talk about the standard range of combustible gas alarm detection.
When the concentration of combustible gas in the air reaches its lower explosion limit, we call the explosion risk of combustible gas environment in this place 100% LEL. If the content of combustible gas only reaches 10% of its lower explosion limit, we call the explosion risk of combustible gas environment in this place 10% LEL; For the monitoring of combustible gas in ambient air, the environmental risk degree of combustible gas is often directly given, that is, the percentage of the content of the combustible gas in the air and its lower explosive limit is expressed as: [% LEL]; Therefore, this kind of monitoring is sometimes called "explosion detection", and the monitoring instrument used is also called "explosion detector".
