Thermowells

Thermowells
Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream. A thermowell is typically machined from solid bar stock and gun-drilled to ensure a long straight bore that closely approximates the diameter of the installed sensor. The thermowell protects the instrument from the pressure, flow-induced forces, and chemical effects of the process fluid.
