PT-100 platinum resistance thermometers (PRTs) are an excellent choice for use as cryogenic temperature sensing and control elements in the range from 30 K to 873 K (-243 °C to 600 °C). Over this temperature span, PRTs offer high repeatability and nearly constant sensitivity (dR/dT). Platinum resistors are also useful as control elements in magnetic field environments where errors approaching one degree can be tolerated. PRTs are interchangeable above 70 K. The use of controlled-purity platinum assures uniformity from one device to another.

Features:

  • Temperature range: 14K to 873K (model dependant)
  • Confirms to IEC 751 standards down to 70K
  • High reproducibility: +/-5mK at 77K
  • Low magnetic field dependence above 40K
  • Excellent for use in ionising radiation
  • SoftCalTM calibration available
  • Non-magnetic packages available (all PT-102 and PT-103 variants)

 

PRTs experience rapidly decreasing sensitivity below approximately 30 K. They should be calibrated in order to achieve maximum accuracy for use below 100 K. The plot illustrates platinum sensor conformance to the IEC 751 curve.
