LPG gas leak detector Sensor/ kitchen nature gas leak sensor

 

MP4 flat surfaced sensor is used for flammable gas detection, which adopts advanced flat production 

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. When the target gas exists, the higher the concentration of target gas in the air, the higher 

conductivity of sensor is. Use simple electro circuit to convert the variation of conductivity to output signal corresponds to gas concentration.

 

Features                                            

* High selectivity                                               

* High sensitivity to Methane

* Small size 

* 5V rated voltage, low consumption                                   

* Fast response and resume

* Good stability and long life                        

* Simple drive circuit

 

 

Application

Widely used for household harmful gas detection and 

automatic exhaust, living air device.
