π§° 304 SS Threaded Thermowell
This 304 stainless steel thermowell protects compatible thermocouple and RTD temperature sensors from direct exposure to the process. Its threaded design allows the temperature sensor to be removed or replaced while the thermowell remains installed.
The thermowell features a 0.260" bore, 4" U-length, 3/4" NPT process connection, and 1/2" NPT instrument connection for common industrial temperature measurement installations.

Compliance & Risk Mitigation
π‘οΈ Isolates sensors from direct process exposure
π§ Allows easier sensor removal and replacement
π§± 304 stainless steel provides corrosion resistance
π Correct insertion supports measurement response
π© NPT connections support secure installation
π‘ Proper probe fit supports heat transfer
β οΈ Verify process conditions before installation
Verify thermowell material, bore, U-length, process and instrument threads, sensor dimensions, process media, temperature, pressure, flow velocity, and vibration requirements before installation. Thermowell suitability depends on the specific process conditions. The thermowell itself does not require calibration; calibration requirements apply to the thermocouple or RTD and the complete temperature measurement system.
