Description

Overview
  • 4-channel premium thermopile for measurement of carbon compounds at high CO2 concentrations


Key facts
  • High detectivity: up to 6.27*10^8 cm√Hz/W with krypton-filled TO housing
  • High sensitivity: up to 171 V/W
  • Target gases: CO (CWL: 4650 ± 40 nm / HBW: 180 ± 20 nm), CO2 (CWL: 4415 ± 30 nm / HBW: 60 ± 10 nm), Hydrocarbons (CWL: 3400 ± 20 nm / HBW: 140 ± 20 nm)
  • Integrated thermistor for reference temperature determination
  • Operating temperature range: -20 to 85 °C
  • Signal quality comparable to pyroelectric detectors; suitable alternative in NDIR component range


Description
  • The narrowband IR filters are optimized for the measurement of carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbons. An integrated thermistor enables reference temperature determination; an interference absorber converts radiant energy into thermal energy, which the thermocouples convert into electrical energy.
  • The detector is suitable for ambient temperatures between -20 and 85 °C and for applications in industry, aerospace and medical fields, such as vehicle exhaust gas measurement, process analysis or industrial gas measurement.
  • The sensor is based on 4 chips, each containing 200 bismuth antimony/antimony thermocouples, and a krypton-filled TO housing, which enables the high detectivity and sensitivity. The signal quality is comparable to that of pyroelectric detectors and offers an alternative in the NDIR component range.
