Specifications and Features
Mounting Styles
Consider process conditions and pipe or tank material to ensure the mounting style will be adequate for the application.
Threaded
Connection: Threaded into process pipe or tank
Easy installation and removal
Lowest pressure rating of the mounting configuration options
 
Flanged
Connection: Bolted to a mating flange on a process pipe or tank
Manufacturing configurations: full and partial penetration welds
Manufactured in accordance with ANSI B16.5
Flange to stem weld is in accordance to ASME Section IX
Full traceability with material certifications available on request
 
Welded
Connection: Permanently welded to a process pipe or tank
Highest pressure rating and are generally used in applications with high velocity flow, high temperature, or extremely high pressure
Leak-proof seal
Stem Profile
The stem is the part of a thermowell inserted into the process piping or vessel. Factors to be considered when selecting a stem style include the process pressure, required response speed of the measurement, drag force of the fluid flow on the well, and the wake frequency.
Straight
Diameter: Same along the entire immersion length
Design: Strongest with largest profile to the process
Drag: Highest compared to other styles with the same root diameter
Response time: Slowest due to large tip diameter
 
Tapered
Diameter: Uniformly decreases from root to tip
Design: Medium. Good compromise between straight and stepped thermowells
Drag: Medium. Less than straight style, but greater than stepped style
Response time: Average. Faster than straight style, and slower than stepped style
 
Stepped
Diameter: Two straight sections with the smaller diameter straight section at the tip
Design: Least profile exposure to the flowing process
Drag: Lowest of all styles
Response time: Quickest due to the smaller tip
