NR Series Sheathed Resistance Thermometers

Sheathed resistance thermometer is sealed and filled with a powder of inorganic insulator (highly pure magnesium oxide) inside metal protective tube (sheath) with a platinum resistance element. It is excellent in insulation, sealing, and vibration resistance.

Models

Z-Terminal Box Type

NRZS1-0

Headless Type

NRHS1-0


Features

  • The protective tube has excellent corrosion resistance due to the elimination of the internal air layer
  • The sensor provides high sensitivity and excellent response corresponding to 2-3 times that of ordinary resistance thermometers
  • The sensor is resistant to vibrations and mechanical shock
  • The Z-type terminal head with a hatch structure ensures easy cable connections
