Catalytic LEL Sensors

Catalytic bead combustible gas sensors basically consist of hot filaments (active and reference elements) enclosed behind a sintered stainless steel flame arrestor. The active element is treated with a catalyst to effectively burn or oxidize the gas while the reference element is nonreactive and provides compensation for ambient conditions; temperature and humidity. The two elements are configured in a Wheatstone bridge whereby exposure to combustible gas imbalances the bridge and generates an electrical output directly related to gas concentration. The catalytic gas sensor is not selective and detects numerous combustible gases and vapors. The Mil-Ram catalytic sensor achieves exceptional zero stability by providing excellent gas response at comparatively low operating temperatures. The lower operating temperature provides for long term stability and extended service life.
