Thermowells - NOSHOK
Thermowells protect temperature sensors from pressure, flow, corrosion and abrasion. They also let you remove sensors for replacement or calibration without draining or shutting down the process.
Thermowell Types
- Threaded thermowells – common for general service
- Socket weld and weld-in – high-pressure installations
- Flanged thermowells – easy removal and corrosive service
- Sanitary thermowells – tri-clamp for food and pharma
- Tapered and stepped stems – strength and fast response
Choosing a Thermowell
Select material, insertion length, bore size and connection. For high-velocity flows, perform a wake frequency calculation to avoid stem failure.
Centro supplies thermowells for temperature sensors and thermometers.
