Infrared Gas Sensor - MPY20-HC-CH4

Product Specification

Product overview：

NDIR gas sensor detects gas by causing molecular vibration of target gas by incident infrared rays, and using the phenomenon that it can absorb infrared rays with a specific wavelength. The transmittance of infrared rays depends on the concentration of the target gas. MPY20 series 4 series gas sensor developed by Meisi Pioneer is a kind of NDIR gas sensor, which can detect carbon dioxide, methane and propane. Its shell is made of stainless steel, explosion-proof design, good anti-interference, high sensitivity and long service life.

The gas sensor based on the infrared absorption principle has the following strengths: good stability, strong selectivity, no oxygen dependence, wide range of detection, long service life, long maintenance cycle, powerful anti-jamming capability, etc. It becomes the gas detection development trend and can rapidly replace gas sensor based on the traditional principle.

MPY20-HC-CH4 infrared gas sensor is designed with the latest technology, and achieves the constant working current of sensor when adopting low power processor and infrared source to control the overall power consumption, to guarantee the power circuit is free from the current shock influence and the sensor runs more stably.
