Where should a fixed gas detector sensor be mounted? - Gas ...

Gas Detection Sensor Mounting Height and Location Guidelines: It is important to mount the gas detection heads in areas that are most likely to first be exposed to a gas leak, or that are most representative of the gas levels in the area being monitored. Here are some criteria to consider: Density of the gas: When detecting for LEL levels of gases and vapors, the density of the gas should be ...

CORRECTION FACTORS FOR COMBUSTIBLE GAS (LEL) SENSORS

RAE Systems LEL sensors can be used for the detection of a wide variety of combustible gases and vapors that exhibit different responses. Because LEL sensors use a diffusion barrier to limit the gas flux to the catalytic bead, they tend to have the greatest sensitivity to high-diffusivity compounds. Therefore, they are substantially more sensitive to small molecules like hydrogen and methane ...
