High Temperature Gas Measurement Module

High Temperature Gas Measurement Module

06 June 2019

Electro Optical Components offers a high temperature gas measurement module that can operate up to 190°C.  The module is based on the NDIR (non-dispersive infrared) principle.  The module has special infrared components developed to withstand the 190°C environment:

  • 2 channel thermopile detector contains two thermopile chips with IR narrow bandpass filters one for CO2 (or other gases) and one for the reference channel.
  • A special infrared source was developed for working at high ambient temperatures.
  • The measurement chamber (in the hot environment) is connected to external electronics mounted away from the heat.

The gas you are measuring fills the measurement chamber. Infrared radiation from the source passes through the gas and generates a signal voltage in the thermopile infrared detector. One channel of detector has a narrow band filter with the passband that is the same as the wavelength absorbed by the gas to be detected. The presence of the target gas inside the chamber causes a drop of the output signal of the detector.  This drop is directly related to the gas concentration present, so you can determine gas concentration.

This high temperature module can be used for gas analysis in applications including: Medical, Refinery, Mining, Automotive and Semiconductor Instrumentation.

These high reliability NDIR gas sensor modules are available in North America from:
