Metallic and Non-Metallic Sheathing for Thermocouples and Resistance thermometer

Metallic and Non-Metallic Sheathing

Metallic tube, most commonly stainless steel, has mechanical advantage and higher thermal conductivity; they are generally immune to thermal shock.

Metallic sheath can be used at temperature up to 1150ºC.

Ceramics are superior when high purity is required to avoid sensor or product being contaminated at elevated temperature.
