Winsen/MP-7 carbon monoxide sensor gas alarm probe CO gas sensor -78675
product detail
Product Details:
MP-7 type carbon monoxide detection with planar semiconductor gas sensor using advanced planar thick film production process, from the heater and micro-Al2O3 ceramic substrate formed on the metal oxide semiconductor material composition, with the electrode lead leads, packaged in the metal tube seat, Inside the cap. Using high and low temperature cycle detection method to detect carbon monoxide (1.5V), high temperature (5.0V) when cleaning low temperature adsorption of impurities in the gas. The conductivity of the sensor increases as the concentration of carbon monoxide in the air increases, and the change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.
Application:
Widely used in household carbon monoxide gas leak alarm, industrial carbon monoxide gas alarm and portable carbon monoxide gas detector.
