Thermopile Detector / Radiometer
Temperature Sensor Module

Micro-Hybrid Electronic GmbH produces high performance thermopile detectors as well as pyroelectric infrared detectors and IR sources (Micro-Hybrid IR Components Catalog). View the Micro-Hybrid video at the bottom of this page detailing their history and capabilities.

Detectors that measure radiation by means of the change of temperature of an absorbing material are classified as thermal detectors. Thermal detectors respond to any wavelength radiation that is absorbed and can be made to respond over a wide range of wavelengths.
  • One of the most common thermal detectors used in the infrared (IR) applications is the thermopile.
  • The most sensitive thermopile (higher Detectivity) is made from bismuth-antimony (BiSb) instead of silicon. Micro-Hybrid uses only bismuth-antimony (BiSb).

Infrared Pulsed IR Sources

Thermopile detectors are voltage-generating devices, which can be thought of as miniature arrays of thermocouple junctions.
Micro-Hybrid GmbH is certified to TS 16949:2009 and ISO 9001:2008. Copies of these certifications are under Technical Notes. These certifications are a reflection of their commitment to quality and product improvement.

Applications include:

  • Non-contact temperature measurement
  • Spectrometers
  • Tympanic thermometers
  • Gas analysis
  • Process temperature monitoring
  • Fire & flame Detection
  • Household appliances
  • Explosion detection
  • Radiometers
  • Presence monitor
  • Far Infrared (FIR) detection up to 300μm and beyond
Each channel of the thermopile detector is fitted to the application by using an infrared filter or window. Micro-Hybrid has a broad selection of Standard Filters and Windows for these applications. Custom Filters and windows are also available.

To avoid damaging thermopile detectors during soldering and cleaning, consider using sockets.
