Straight Thermocouples

 

Single Metal or Ceramic Protection Tube | SH Head

Straight industrial process thermocouples with single metal or ceramic protection tubes are typically used to monitor temperatures during Heat Treating, Die Casting, Hot Dip Galvanizing, Waste Incineration, Cement Kilns and Glass Production. The straight industrial thermocouple assemblies with metal tubes and base metal elements can be used up to 2400°F. Higher process temperatures up to 2700°F can be monitored by straight industrial thermocouples with Noble or Platinum thermocouple elements protected by ceramic tubes.

Metal protection tubes are available in all high temperature stainless steels and Nickel Alloys. Ceramic protection tubes are available in Mullite, Alumina and Zirconia.
