above +1,200 °C, up to about +1,800 °C

Extreme Temperature Sensors

Above 1,200 °C, base-metal sensors drift quickly. Noble-metal thermocouples, ceramic protection and non-contact pyrometers become the practical choices.

Ranges are typical guidance. The right choice depends on sheath material, insulation, process atmosphere and duty cycle.

Selection tips

  • Accuracy vs. range: RTDs give the best accuracy at lower temperatures; thermocouples cover wider and higher ranges.
  • Response time: smaller sheath diameters and grounded junctions respond faster.
  • Sheath and protection: match the sheath or protection tube to temperature, pressure and corrosion.
  • Atmosphere: oxidising, reducing or sulphur-bearing atmospheres affect which sensor types last.
  • Vibration: use mineral-insulated construction, spring-loading or a thermowell where vibration is present.
