Product Specification

Natural Gas Sensor Methane Sensor CH4 Sensor MQ-D4

 

Specification:

MQ-D4 type semiconductor natural gas sensor is mainly used in leak detection, monitoring, alarm device and intelligent gas leak alarm system of natural gas, methane gas, gas, marsh gas etc, it uses advanced flat production process, from the heater and micro- Al2O3 forming a metal oxide semiconductor material constituting the ceramic substrate, with the electrode wire leads, encapsulated in a metal tube housing, cap; When detecting the presence of gas, the gas concentration in air is higher, the higher the conductivity sensor, using a simple circuit that can change the conductivity of the gas is converted to an output signal corresponding to the concentration.
