Threaded Thermowells

Threaded Thermowells

The Ashcroft® threaded thermowells are utilized when pressure, high velocity and corrosive process media exist. This serves to isolate and protect the sensing instrument, and permits removal of a sensing instrument without shutting down the process.
The Ashcroft® threaded thermowell isolates and protects a temperature instrument’s sensing element from pressurized, high velocity and corrosive media. 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.
