Using the Pt 100 & Thermocouple for Air Steam, Laboratory and Industrial Applications

Omega provides temperature probes for laboratory and industrial applications. The probes are manufactured with different types of sheath styles and mechanical fittings that are suitable for various measurement conditions.

Temperature probes may be specified to a user’s precise requirements by the sensor type in an air-stream or closed-end style sheath, probe length, accuracy, different threads, and wire material in unshielded and shielded versions.

  • Thermocouples type J, K, T, N. Accuracy IEC Class 1
  • Pt100 in Class A, 1/3 DIN or 1/10 DIN
  • Pt1000 in Class A, B or 1/3 DIN
  • Closed end or air stream style sheaths
  • Diameters of 2, 3 or 6 mm
  • Standard lengths up to 500 mm
  • Probes individually pressure and insulation tested
  • Wide range of lead wire materials

The following table summarizes the available options.
