Thermo-Electra ME 7089 Tube skin thermocouple with weld pad and cable

Product Code: ME7089

Manufacturer: Thermo-Electra


Thermo-Electra boiler and Furnace thermocouples are welded to the tube surface with a V-tip or Pad. The typical lifetime of these tube skin thermocouples at continuous operation lies between 4 to 6 years. Sheath material for gas-fired furnaces is made from SS310, Inconel 600, or Hastelloy X. For oil fuel-fired furnaces best results are achieved with a sheath material Hastelloy X or Haynes HR160. An additional braided sleeve of Refrex / Fibrefrax protects the sheath from aging acceleration and prolongs the sensor lifetime.
