Socket Weld Thermowells

Socket Weld Thermowells

The Ashcroft® socket weld thermowell is used when pressure, high velocity and corrosive process media exist. Serving to isolate and protect, it also allows the sensing instrument to be removed without requiring process shut down.
The Ashcroft® socket weld thermowell isolates and protects a temperature instrument’s sensing element from pressurized, high velocity and corrosive media. These are typically used where exposed threads may collect contaminants such as in food processing or pharmaceutical production. They ensure longer life and accurate measurement while allowing the sensing instrument to be removed without shutting down the process. A wide selection of materials, sizes and dimensions are available.
