Single-Element Pyrodetectors


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.

Product List

Part Number
PYS 3198 TC GX (LHi 807)

PYS 3198 Single-Channel Pyrodetector

Excelitas Single-Element Pyrodetectors combine one sensing element with the optical window, making them ideally suited for gas measurement and monitoring applications. The PYS 3198 TC GX (replacement to LHi 807) is a single channel, parallel format temperature-compensated elements detector based on lithium-tantalate (Li-Ta).
Part Number
PYS 3428 GX GY TC (LHi 814)

PYS 3428 Dual-Channel Pyrodetector

As a Dual-Channel, Single-Element Pyrodetector, the PYS 3428 (replacement to LHi 814) includes two single-elements which are each thermally compensated. Each output is optically linked to an individual optical window within the TO-5 Metal Housing. For each window a variety of narrow-band optical filters are available to meet a range of specific sensing requirements.
