Zhengzhou Winsen Electronics Technology Co.,Ltd MC112/MC112C/MC112D Catalytic Flammable Gas Sensor Profile MC112/ MC112C/ MC112D adopts catalytic combustion principle, and its two arms of electric bridge consists of a test element and a compensate element. The resistance of the test element rises once it meets the combustible gases, in the same time, the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The compensate element, as a conference, has the function of compensating temperature and humidity. Features It has good sensitivity...

Sensitivity with different voltage Long-term Stability The drift in air per year is within ±2mV, in 1%CH4 is within ±2mV. For a short period storage (in 2 weeks), the sensor need be galvanical continuously for 8 hours to reach stability. For...

Zhengzhou Winsen Electronics Technology Co.,Ltd Cautions 1. Following conditions must be prohibited 1.1 Exposed to organic silicon steam Sensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. 1.2 High Corrosive gas If the sensors are exposed to high concentration corrosive gas (such as H2S, SOX, Cl2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. 1.3 Alkali, Alkali...
