Stepped Thermowell

Stepped Shank

Description:
Has a larger diameter at the base which “steps” down to a smaller diameter for the rest of the length, usually near the tip.

Real-Life Application:
Used when the fastest possible response time is the most critical factor. Common in process control loops and laboratory settings.

Specification:
The reduced mass at the tip allows for rapid heat transfer to the sensor. Its strength is less than a tapered well but better than a straight one.

Materials:
Primarily Stainless Steel (316, 304), as it’s often used in less corrosive, high-response applications.
