Thermowells

Built for Durability. Designed for Precision.

MTI Industrial Sensors manufactures a full line of thermowells and protection tubes engineered to safeguard temperature sensors in high-pressure, high-velocity, and corrosive environments.

Whether you’re measuring temperature in process piping, tanks, or vessels, our thermowells ensure accurate readings and long sensor life by isolating your RTDs or thermocouples from direct media exposure.

Available thermowell Styles

Threaded Thermowells

For easy installation in piping systems; available in tapered, straight, or stepped designs.

Flanged Thermowells

Ideal for high-pressure or high-temperature applications; ANSI and custom flange options.

Weld-In Thermowells

For permanent installation in process systems; offers excellent strength and reliability.

Van Stone Thermowells
