Thermowells are manufactured from drilled bar stock and have threaded NPT process connections or flanges for direct immersion into high pressure or corrosive applications. The thermocouple element is mounted into the thermowell and is typically spring loaded for positive contact to the bottom wall of the well. This allows for the best possible response to temperature changes during operation.
Cast iron or aluminum screw cover heads are used to terminate the thermowell assemblies. The thermocouple element can be constructed of ceramic insulated thermocouple wires or mineral insulated cable for increase durability. The thermowell itself can be machined in a variety of designs and insertion lengths. Most wells are manufactured of 304 stainless steel or 316 stainless steel, however other alloys are available.
