Thermowells are designed to add additional protection to temperature sensors such as thermocouples and RTD assemblies. They isolate the temperature sensor from the application environment, allowing for longer sensor life. Offered in many different materials such as carbon steel, stainless steel, Inconel® and Hastelloy®, thermowells are available in straight bore, tapered bore, weld in and flanged mount.
