Infrared Gas Detectors Working Principle - Inst Tools

Infrared gas detection is based upon the ability of some gases to absorb IR radiation. Many hydrocarbons absorb IR at approximately micrometers and in this region H2O and CO2 are relatively transparent. As mentioned earlier, there are some hydrocarbons and other flammable gases that have poor or no response on a general purpose IR sensor. In addition to aromatics and acetylene, hydrogen ...

Flammable Gas Detection | Johnson Matthey Technology Review

All three types of flammable gas sensor considered in this paper involve reactions between the analyte, which is usually a reducing gas, and a solid surface. The reactions which take place are governed by the nature of the surface, and each of the three types of sensor described depend on the unique adsorption properties of the platinum metals. This, however, is manifested in different ways. The calorimetric sensor …

Flammable Gas Detection | Johnson Matthey Technology Review

This and similar types of sensor are widely used in various kinds of flammable gas detection instruments, which may be hand held or fixed installations. Gas usually reaches the sensing element by diffusion through a sinter exposed to the atmosphere in a typical configuration shown in Figure 2. The effect of temperature on the out of balance voltage and on the power drain of a typical sensing ...

How do you select a calibration gas? - SEMA Gases

The flammable gas type in the various gas mixtures is most of the times methane or iso-butane and sometimes propane. The flammable gas concentration of each specific flammable gas is always a %Vol which is equal to 50%LEL. Where gas mixes of different brands differ from each other are the height of the ppm concentrations of toxic gases such as ...
