Frequently Asked Questions

What is the WINTERS threaded thermowell used for?

The WINTERS threaded thermowell protects temperature sensors in industrial piping and vessels. It is commonly used in oil and gas, chemical processing, and power generation to shield thermocouples or RTDs from corrosive media, high pressure, and flow velocity while allowing sensor replacement without system shutdown.

What are the specifications of the WINTERS TBR3550-ST thermowell?

The WINTERS TBR3550-ST is a brass straight-shank threaded thermowell with a 4-inch stem length, 2.5-inch insertion length, and 1/4-inch stem diameter. It has a maximum operating pressure of 5,000 psi at 70°F and a maximum operating temperature of 400°F/204°C. The MPN is TBR3550-ST.

How to select the correct WINTERS thermowell for a process?

Select a WINTERS thermowell by matching stem length, insertion length, and stem diameter to your sensor and process connection.
