Nipple-Union-Nipple-Thermowell Style Diagram

Product Name: Nipple-Union-Nipple-Thermowell Style Application: Temperature Sensor For General Purpose, foundry, Sanitary, Marine, Heavy Duty and Special Applications
RTD Element Type: Pt100, Pt1000, 2x Pt100 Pt1000 Operating temperature: -200 C to +500 C Max

The Mineral Insulated Nipple-Union-Nipple-Thermowell Style RTD is built for use in applications where facile removal of the spring loaded sensor is a required option without the need to turn off the system. Thermowells are utilized to ensure temperature sensors used to monitor mechanical procedures while allowing accurate measurement. A thermowell comprises of a tube closed toward one side and mounted in the process stream. A temperature sensor is inserted in the open end of the tube, which is ordinarily in the open air outside the procedure piping or vessel. The procedure fluid transfers heat to the thermowell wall, which in turn transfers warmth to the sensor. Since more mass is available, the reaction time of the sensor can be reduced. In any case, if the sensor fails it can easily be supplanted without draining the vessel or piping. To acquire accurate temperature estimation the recommended thermowell immersion length is ten times the outside diameter of the tip. The thermowell shields the instrument from the pressure, flow-induced powers and chemical effects of the process fluid. Normally a thermowell is made from metal bar stock bored to accept the temperature sensor with a NPT thread or flange for process mounting.
