Solid-pack thermocouples are temperature sensors with a large diameter protective tube of φ10 to 22 mm that combine the sensitivity of sheathed thermocouples with the robust required for industrial use. High-purity magnesium oxide is densely packed between the protective tube and the wire and compressed, and the thick protective tube provides excellent durability for long periods of continuous use in high temperatures and hostile environments.

The thick protective tube is densely packed with high-purity magnesium oxide, allowing it to be used for a long time.

This sensor is a high-performance thermocouple that combines the sensitivity of a sheathed sensor with robust and durability of a general industrial sensor. structure is a solid type in which the gap between the protective tube and the thermocouple wire is densely filled with insulation material. It has excellent response and vibration and shock resistance, and the use of a thick protective tube ensures outstanding durability even when used continuously for long periods of time in high temperature and hostile atmospheres.

  • There is no air space inside the protective tube, and the use of a thick protective tube provides excellent heat and corrosion resistance and a long service life.
  • It has high sensitivity and responsiveness 6 to 10 times faster than standard thermocouples.
  • It has a solid type structure that is resistant to vibration and mechanical shock. It can also be bent to make an L-shaped thermocouple without an elbow.
  • This terminal box has structure that makes it easy to connections the compensation conductors.
  • Two-pair thermocouples (double elements) are also available.
