HIS Series

 

HIS Series

The HIS Series (Heimann Integrated Sensor) devices include thermopile sensor chip, application specific optical filter and an ASIC for analog signal conditioning in a standard TO-39 metal housing. The ASIC amplifies the chip voltage and generates an analog voltage output signal. An integrated linear temperature reference is used for ambient temperature compensation. In addition to the single channel version (HIS A), we offer a dual version (HIS E222) for gas concentration measurements. For temperature measurements, we have different options of standard temperature filters at our disposal. For gas detection, we offer special filters providing the gas specific center wavelength (CWL) and narrow half power bandwidth (HPBW).

  • Integrated linear temperature reference
  • Standard TO-39 package
  • Four different thermopile sensor chips sizes available
  • Large number of filter options
  • Large operating range -20°C to 120°C
