Thermowell sensor assemblies 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 with the bottom wall of the well, allowimg 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 increased 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. Various well materials and terminal heads are available as options
TDW style thermowell thermocouples from Durex Industries can be supplied with thick wall base metal materials and construction for corrosive, high velocity, and high pressure. Typical industrial process applications include chemical, petrochemical, metal treating, power generation, waste treatment, and diesel engine testing.
Temperature sensor thermowell assembly TDW1 features a thermocouple element protected by a drilled bar stock thermowell. Nipple, thermowell assembly.
Temperature sensor assembly TDW3 features a thermocouple element protected by a flange thermowell.
