Standard Socket-Weld Barstock Thermowell
Temperature / Thermowells / TW201 TW202 TW203

Standard Socket-Weld Barstock Thermowell Picture
  • Machined from solid barstock.
  • Socket-Weld Connection
  • Stepped, Tapered and Straight stem profiles.
  • 1/2", 3/4" and 1" NPS connections are standard.
  • Standard bores for 6mm, .250 and .375 diameter probes.
  • CRN available on all models.

Barstock models are machined from one solid piece of Hexagon or Round Bar. They offer the highest pressure ratings and strength due to their one piece construction.

Socket-Weld for welding in place to a standard pipe size weldolet, pipe adaptor or directly to a pipe size process opening. The process connection diameter matches standard pipe dimensions.

Stepped, Tapered and Straight stem profiles are available. Custom dimensions can be supplied on request.

Stepped thermowells are the most popular, they have a thick robust main stem section with the last 2.5 inches of the stem having a diameter of .50
TW201 - Socket-Weld Stepped Barstock

Stepped thermowells are the most popular, they have a thick robust main stem section with the last 2.5 inches of the stem having a diameter of .50" to reduce thermal lag offer better time response.

TW202 - Socket-Weld Tapered Barstock

Tapered thermowells are the strongest mechanically. The stem starts off at a large diameter (the root or shank diameter) and tapers down to the tip diameter. This design has a higher natural frequency making them more appropriate for systems with extreme dynamic conditions such as process lines with media flowing at high velocity.

Tapered thermowells are the strongest mechanically. The stem starts off at a large diameter (the root or shank diameter) and tapers down to the tip diameter. This design has a higher natural frequency making them more appropriate for systems with extreme dynamic conditions such as process lines with media flowing at high velocity.
Straight stem thermowells are simular to stepped stem but the large diameter extends to the Tip. Time responce is slower with this style. The heavy wall on the entire length of the stem gives them longer service life in conditions where erosion and/or corrosion may attack the stem. They are also well suited for the uniform application of protective coatings.
TW203 - Socket-Weld Straight Barstock

Straight stem thermowells are simular to stepped stem but the large diameter extends to the Tip. Time responce is slower with this style. The heavy wall on the entire length of the stem gives them longer service life in conditions where erosion and/or corrosion may attack the stem. They are also well suited for the uniform application of protective coatings.
