Zhengzhou Winsen Electronics Technology Co., Ltd MP810 Hydrogen Gas Sensor Profile MP801 gas sensor is for hydrogen. It adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding...

Zhengzhou Winsen Electronics Technology Co., Ltd temperature characteristic The following figure shows the characteristic curve of the sensor affected by temperature and humidity The vertical axis represents the sensor resistance ratio Rs/R0, and Rs and R0 are defined as follows: The resistance value of RS sensor in 1000ppmH2 under different temperature conditions, and the resistance value of R0 in 1000ppmH2 under normal temperature conditions. Cautions 1 .Following conditions must be prohibited 1.1 Exposed to volatilizable organic silicon steam Sensing material will lose sensitivity and never...

Zhengzhou Winsen Electronics Technology Co., Ltd www.winsen-sensor.com The sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorine. 1.4 Touch water Sensitivity of the sensors will be reduced when spattered or dipped in water. 1.5 Freezing Do avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 1.6 Applied higher voltage Applied voltage on sensor should not be higher than stipulated value, even if the sensor is not physically damaged or broken, it causes...

Zhengzhou Winsen Electronics Technology Co., Ltd www.winsen-sensor.com 2.4 Long time exposed to adverse environment No matter the sensors electrified or not, if exposed to adverse environment for long time, such as high humidity, high temperature, or high pollution etc., it will influence the sensors’ performance badly. 2.5 Vibration Continual vibration will result in sensors down-lead response then break. In transportation or assembling line, pneumatic screwdriver/ultrasonic welding machine can lead this vibration. 2.6 Concussion If sensors meet strong concussion, it may lead its lead wire disconnected....
