The high sensitivity Thermopile single channel detector with 80 bismuth antimony/antimony thermocouples is based on MEMS technology. The very high detectivity of up to 12.2*108 cmHz1/2/W, as well as the high sensitivity of up to 501 V/W, are made possible by two factors. The detector has a membrane optimized for use with optical systems - The radiation-sensitive thermocouples are aligned to a focal point. A krypton gas filling further increases the detectivity and sensitivity of the thermopile. The filter measures in the transmission range from 8 to 14 µm. This means that there is no absorption in the H2O bandwidth range. Influences due to humidity are excluded. These properties allow the use in demanding applications for non-contact temperature measurement in industry, such as temperature monitoring of melting processes in the glass and plastics industry or temperature monitoring of engines and brakes in the automotive sector.
The detector can be used at ambient temperatures between -20 and 85 °C. An integrated thermistor for intrinsic temperature monitoring can compensate external temperature influences.
Customer-specific adaptations are possible at any time. Our sales team will be happy to advise you on this, as well as on-scale prices for larger quantities.
