Description
The premium dual channel thermopile has been specifically designed for demanding measurement applications for the analysis of N2O (nitrous oxide) in environments from -20 to 85 °C. It achieves an exceptionally high detectivity of up to 6.27*108 cm√Hz/W and a sensitivity of up to 171 V/W. This signal quality is comparable to pyroelectric detectors. The infrared filter with a CWL of 4525 ± 20 nm and a HBW of 83 ± 6 nm is precisely matched to the optical characteristics of the target gas. Medical technology, especially patient and anesthetic gas monitoring, are typical application fields for the MTS2SENS200 nitrous oxide.
The integrated thermistor for reference temperature determination and an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) complete the detector. The dual detector MTS2SENS200 nitrous oxide is based in the core on 2 chips with 200 bismuth-antimony/antimony thermocouples each. Thermal diffusion currents between the different metals generate the measurement signal by the resulting electrical voltage (Seebeck effect).
