Sanitary Thermowells

Sanitary Thermowells

The Ashcroft® sanitary thermowell is utilized when pressure, high velocity and corrosive process media exist. This serves to isolate and protect the sensing instrument in sanitary applications.
The Ashcroft® sanitary 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. The polish and large radius between the stem and flange support easier cleaning. Thermowells 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.
