Single-Element Pyroelectric Detectors are often applied for temperature and gas measuring applications in one-channel or dual-channel variants, which is then one output per element. Single-Element variants are offered as thermally compensated devices. The principle of Gas monitor application is called NDIR. NDIR requires Detectors with narrow-band optical filters. Excelitas provides a range of suited filter windows for those gases which show an absoption band in the IR spectral range.
