Wide Range Resistor for UHV Use - 343-PT100-C1

The wide range PT 100 resistor available from Allectra is a class A resistor that enables accurate measurement of temperature between −200 °C and +750 °C. The class A resistor provides very low tolerances and higher stability in comparison to thermocouples.

The resistor comes in a standard version, or along with four cables connected. It is also available as a set that includes screw-on clamp and thermal contact foil. Users can obtain alternative cable configurations on demand.

It is possible to perform several modifications:

  • Alternative cable length available on request
  • Solder-free crimp connection available on request
  • 3-wire and 2-wire connection available on demand

The following are the recommended alternative cables:

  • 311-KAP-RIB4 (4-way ribbon cable of 0.35 mm)
  • 311-KAPM-035 (diameter of 0.35 mm)
  • 311-KAPM-035-RAD (radiation-resistant wire of 0.35 mm)

The thermal contact foil (317-TCP-20x20) melts at a temperature of 58 °C and offers an optimal contact to the base material at a thermal conductivity of 125 W/mK. It does not contain any filler.
