Thermocouples with Kanthal thermowells for measurement up to 1300 deg C into incinerators and fluesgas are made in type K (NiCr-Ni) and type N (Pyrosil). A solid Stellite or Stelite coated weld overlay thermowell, designed for abrasive flue gas measurement up to 1600 deg C offer protection against wear due to the agressive medium. For temperatures up to 1800 deg C, there are Platinum – Platinum Rhodium thermocouples in the types of R, S and B with Ceramic or Silicon Carbide (SiSiC) protective tubes. For measurement in glass furnaces, plating baths, ovens, flue gas and other harsh environments, we also provide more exotic thermocouple protection tubes next Kanthal, like Haynes, Silicon Carbide, Tantalum, Titanium, Hastelloy and Monel. With the right protection and robust construction can be guaranteed a long life.
