1 PC MPv-820 Hydrogen Gas Sensor

MPv-820 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 to gas concentration. Application Used for hydrogen leakage detection for energy vehicles and hydrogen storage stations Features High sensitivity, fast response speed, long service life, and simple application circuit Specifications Model MPv-820 Sensor Type Semiconductor flat surfaced sensor Standard Encapsulation TO-5 Detection Gas H2 Detection range 100～3000ppm Standard circuit Loop voltage VC 5.0V±0.1V DC Heating voltage  VH  5.0V±0.1V DC Load resistance RL Adjustable Heating consumption PH ≤350mW Surface resistance RS 0.5KΩ～10KΩ(in200ppmH2) Sensitivity(Rs) 0.2~0.6（H2） Rs300ppm/Rs50ppm Standard condition of testing   Temperature, humidity 20℃±2℃；65%±5%RH Standard test circuit VC/VH :5.0V±0.1V Warm-up time 7 days   * The description and specifications might be changed without notice.
