Introduction
The G100 Combustible Gas Detector consists of a sensor housing, sensor components and circuit board. The Detector detects gas concentration over the range of 0 to 100% of the lower explosive limit. The field replaceable probe is sensitive to a wide range of combustible gases.
Operating Methods
The detection method is diffusion and adsorption. Air and gas diffuse through a stainless steel filter and contact both the active and reference detector beads. The heated surface of the active detector promotes oxidation of the combustible gas molecule while the reference detector has been treated not to support this oxidation. The reference detector serves as a means to maintain zero stability over a wide range of environmental conditions. When combustible gas molecules are oxidized on the active detector, incremental heat is generated and its resistance changes. Change in resistance is accurately measured using a Wheatstone bridge circuit.
