An LEL Monitor is an instrument used to detect hazardous levels of a combustible gas or solvent vapor in air, expressed in % LEL, or Lower Explosive Limit. An LEL Monitor is also referred to as an LEL Gas Detection System, LEL Gas …

How infrared sensors measure LEL combustible gas | 201409 ...

+

Sep 03, 2014· Nondispersive infrared (NDIR) sensors are increasingly being used in multisensor instruments to measure LEL combustible gas. But remember, no single type of sensor can detect all types of dangerous gases and vapors. Manufacturers offer different types of sensors to measure combustible gas and VOC vapors. Nondispersive infrared (NDIR) …

This is the minimum concentration of a flammable gas or vapor that will propagate ... most common are butane and propane. They are readily liquefied by pressurizing at

Can Bw Ultra IR LEL Sensor detect propane gas

+

The IR LEL sensors in these product ranges are marginally different in design but will have very similar responses to other hydrocarbons such as propane. However, both of these sensors are linearized to a methane response as is most commonly seen in these types of sensors. This means however that the response to other hydrocarbons such as ...
