PyroMini OEM – Low-Cost Pyrometer for Machine Manufacturers

PyroMini OEM – Low-Cost Pyrometer for Machine Manufacturers


  • Miniature sensing head withstands up to 120°C ambient temperature without cooling
  • Measurement ranges from -20°C to 500°C
  • Choice of outputs: 4-20 mA, 0-10 V DC, Type J or K thermocouple
  • Right-angled cable entry for low-profile installations
  • Stainless steel sensing head, sealed to IP65
  • Fixed emissivity 0.95 – suitable for measuring most non-reflective non-metals, and painted surfaces
  • Not designed or approved for fever detection



Simple – Save installation time and reduce the cost of instrumentation on the machines you build with the PyroMini OEM.

Easy – This simple sensor works straight out of the box with no configuration necessary.

Accurate – Fixed emissivity setting provides accurate measurements on non-reflective materials such as paper, foodstuffs, organic materials, rubber, painted surfaces (including painted metals) and thick plastics.

Compact – Install the sensor where space is limited. The sensing head measures just 55 mm long, with a right-angled cable entry.

Industry standard outputs – A choice of robust industrial analogue outputs including 4-20 mA, thermocouple or voltage allows the sensor to be connected directly to an existing temperature indicator or controller.

Field of View Diagrams

The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air, and accuracy does not change with distance; this is because the sensor detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
