One of the many requirements for entering confined spaces called is the measurement of confined spaces for flammable gases. Prior to entry of a confined space, the level of flammable gases must be below 10% of LEL. The most common sensor used for measuring LEL is the Wheatstone bridge/catalytic bead/pellistor sensor ("Wheatstone bridge").

flammable gases or vapours, or for monitoring concentrations of such gases and vapours within plant. Fixed detectors are particularly useful where there is the possibility of a leak into an enclosed or partially enclosed space where flammable gases could accumulate. 7 A ‘portable’ detector usually refers to a small, handheld device that can be used for testing an atmosphere in a confined ...
20190604· Gas sensing layer: It is the main component in the sensor which can be used to sense the variation in the concentration of the gases and generate the change in electrical resistance. The gas sensing layer is basically a chemiresistor which changes its resistance value based on the. The concentration of particular gas in the environment. Here the sensing element is made up of a Tin …
Mixtures of flammable gases with air, when ignited, produce an explosion. A flammable gas sensor monitors the percentage of ambient gas in the air determining if the concentration is rich enough for the mixture to burn. When a high concentration is reached, best practice is to replace the air with fresh and/or shut down equipment and evacuate personnel from the area. Our flammable gas ...
