The outer sheath of thermocouples is instrumental in protecting the temperature sensors from external force and damage that are mostly a consequence of corrosion, hustling, anomalous high temperature and erosion.
The outer sheath of thermocouples is instrumental in protecting the temperature sensors from external force and damage that are mostly a consequence of corrosion, hustling, anomalous high temperature and erosion. Coating on the thermocouple sheaths shield them from chemical corrosion and mechanism corrosion damages. The coatings are available in Glass Enamel, Ceramic, Stellite, Boron Nitride and Tungsten Carbide.
Things to Consider for Thermocouple Sheath Coat:
Molten Nonferrous metals require coating materials with excellent non-wetting proper
For using in Molting Aluminium, apply Boron Nitride Coating over Stainless Steel
Opt for special Ceramic Coating for increasing the lifespan of sheaths that are used in cement processing kilns, diverse furnace applications and pre-heaters
Confirm if Stellite-Weld Overlay coating is applied on Thermowells used in Ethane, Cracking Furnace for Propane, High Velocity environments like power stations and such applications. The coating promises a longer lifespan. Stellite weld overlay Thermowells last longer than regular Thermowells and are utilised for toughness and immunity to high-temperature erosion.
