MP-5 Flammable gas Sensor

Profile

MP-5 gas sensor is for flammable gases. It adopts multilayer thick film manufacturing technology. The heater

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.

Features:

*

Lower consumption

*

Small size

*

Fast response and resume

*

Highest sensitivity

*

Excellent stability and long life

*

Easy circuit and big signal output

*

Excellent selectivity

Application

It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
