The narrowband IR filters are optimal for the measurement of carbon monoxide (CO) (CWL: 4650 ± 40, HBW: 180 ± 20 nm), carbon dioxide (CO2) (CWL: 4415 ± 30, HBW: 60 ± 10 nm) and hydrocarbons (CWL: 3400 ± 20, HBW: 140 ± 20 nm) with reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm). An integrated thermistor for reference temperature determination and an interference absorber convert the signal as efficiently as possible from radiant energy to thermal energy. The thermocouples then convert thermal energy into electrical energy.
The detector can be used at ambient temperatures between -20 and 85 °C in numerous industrial, aerospace and medical applications: Exhaust gas measurement on vehicles, process analysis or industrial gas measurement.
The basis of the MTS4SENS200 3C-2 carbon dioxide IR thermopile is formed by 4 chips, each containing 200 bismuth antimony/antimony thermocouples. The detector owes its very high detectivity of up to 6.27*108 cmHz1/2/W and sensitivity of up to 171 V/W to this high-performance material and a filling of the TO housing with krypton. The signal quality is comparable to that of pyroelectric detectors and thus offers an additional alternative in the NDIR component range.
