SC Series Sheathed Thermocouples

Data_Sheet
The SC series is sheathed thermocouples, of which thermocouple wire is inserted in a metal protective tube (sheath) and is filled by inorganic insulator (high purity magnesium oxide). The sheathed thermocouples have excellent performance on insulation, airtight and response, and withstand long term continuous operation in various unfavorable atmospheric conditions.

Features

  • Wide temperature range and various models
  • Excellent vibration resistance and corrosion resistance
  • Quick response
  • Easy mounting
