2 sensor chips, each with 200 bismuth-antimony/antimony thermopairs, form the basis of this thermopile detector. Incident IR radiation creates thermal diffusion currents of the two different metals (Seebeck effect). This generates an electrical voltage - the measurement signal for NDIR gas analysis. The signal strength of the highly sensitive IR sensor is comparable to that of a pyro detector: high detectivity up to 6.27*108 cmHz1/2/W and high sensitivity up to 171 V/W (detector with the filling gas Krypton in the TO housing).
The infrared filter windows are ideal in their optical characteristics for the analysis of flouranes with a CWL of 8620 ± 45 nm and a HBW of 540 ± 45 nm. The interference absorber, an integrated thermistor for reference temperature determination and the reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm) are further important features for reliable measurements in demanding medical applications.
The MTS2SENS200 flourane provides reliable measurements in environments between -20 and 85 °C, e.g. for anesthetic gas monitoring.
Due to our hermetically sealed packaging of the detectors in the TO housing, a filling gas such as krypton can additionally support the performance and longevity of the detector.
Our sales team will be happy to advise you on further graduated prices and possible individual, technical adaptations.
