Request Information
Standard Flanged Thermowells are available in a variety of materials, flange types, flange sizes, and pressure ratings. They are also available in various lengths and with optional lagging extensions. Thermowell specifications should be determined based on process conditions which include strength, temperature, pressure and corrosion-resistance requirements. Standard flanged thermowells are supplied with a straight shank and are designed with a 0.260" or 0.385" bore diameter to accommodate sensing elements with a 0.252" or 0.377 maximum diameter, respectively. These wells are available as separate components or as part of complete sensor assemblies.

 N/A ("U" length for non-lagging wells) = "S" - 2"
("U" length for lagging wells) = "S" - 2" - "T"
(To solve for "T"), "T" = "S" - "U" - 2" (When "U" and "S" are specified)
