Sanitary, Weld-In Thermowells are offered in 304 and 316 stainless steel. They are available in a variety of lengths, process connection sizes, and optional lagging extensions. The thermowell is to be welded into a tank or vat with a full crevicefree fillet-weld to prevent corrosion, bacteria growth, and product contamination. Thermowells are supplied with a surface finish that meets or exceeds 32 µin Ra. Surface finishes of 15 µin Ra or better are available upon request. They are designed with a standard 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.
