Pyroelectric detectors are used in gas analysis. Each gas can be detected using a very specific wavelength - the so-called absorption wavelength.
Moisture is often tested at the wavelengths 1.94 μm and 2.9 μm; however, in this case, the absorption wavelengths of CO2 overlap the signal: with these wavelengths, the moisture of the gas mixtures can actually only be determined using complex measurement equipment. With the right filters and a suitable light source it is also possible to achieve a reliable measurement with simple NDIR measurement devices.
LASER COMPONENTS brings three new filters on the market that are selected in such a way as to significantly reduce the crosstalk to other gases to achieve uncomplicated measurements with NDIR measurement devices.
For the measurement of methane (CH4): lCWL = 7.91 μm ±160 nm
For the measurement of alcohol mixtures: lCWL = 9.50 μm ± 450 nm
For the measurement of moisture (water vapor): lCWL = 5.78 μm ±180 nm
