Detectors for Gas Sensing

Excelitas offers a number of thermopile detectors and pyrodetectors for gas sensing and monitoring.

These include thermopile detectors specialized to be equipped with bandpass filters for gas detection e.g. TPiD 1T 0515-Gx, where Gx is one of the Excelitas gas filters. The devices employ chips with large absorber size and have very high signal output for optical gas detection.

The PYSxxxx detectors shown here have been designed for gas sensing applications. They are available with a range of narrow band pass filters for various gas types, in combination with a reference filter. Features include larger element sizes to offer more signal for non-focused optical systems, additional EMI protection and thermal compensation for compensation of thermal effects caused by temperature changes of the housing.
