Description
The MTS1HIGHTEMP is a high-sensitivity, single-channel thermopile detector for precise, non-contact temperature measurement by sensing emitted infrared radiation. The thermopile absorbs the energy, converts it to electrical voltage and produces an output signal. The special chip design and the housing with a soldered filter allow reliable measurements even at high ambient temperatures. The detector is resistant to humidity, aggressive gases and other environmental influences. The high detectivity of up to 12.2*108 cmHz1/2/W and the high sensitivity of up to 501 V/W are achieved by back gassing with krypton. Influences by humidity in the measuring environment are eliminated by a filter used in the transmission range from 8 to 14 µm. There is no absorption in this bandwidth. These properties allow the use in applications of non-contact temperature measurement with high requirements, such as temperature monitoring of thermally indexed process parameters in the metal industry or testing of maintenance-relevant properties in the solar semiconductor industry.
The detector can be used at ambient temperatures between -20 and 180 °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.
