What is the difference between “immersed” and “submerged”?
The term immersed, as it applies to Vulcan immersion heaters and sensors, refers to the portion of the assembly located within the liquid, specifically the heating element or sensor assembly that begins at the face of the bushing, mounting fitting or flange. The term submerged, refers to products that can be completely located within the liquid. Vulcan heaters and sensors can NOT be submerged as the lead wires, enclosures, and other termination constructions are not designed for this purpose.
