Thermowell design
WebbThermowells are cylindrical pressure-tight fittings used to protect the temperature sensors which are inserted into a pipe or vessel in industrial applications. A thermowell is … WebbA thermowell acts as a barrier between a process medium and the sensing element of a temperature measuring device. It protects against corrosive process media, as well as media contained under pressure or flowing at a high velocity. A thermowell also allows the sensing element to be removed from the application while maintaining a closed system.

WebbThermowell is provided to protect the temperature sensor from mechanical damage and corrosion. An extremely sturdy design may increase the life of the sensor but may lead … WebbThermowell Immersion Length The idea behind the immersion length is the temperature sensor characteristic that will be used in the thermowell. Every temperature sensor has it owns characteristic and may vary from one vendor to others. For example an RTD sensor which uses a Pt material that has 100 ohm resistant at 0 oC.
Thermowells are typically installed in piping systems and subject to both hydrostatic and aerodynamic forces. Vortex shedding is the dominant concern for thermowells in cross-flow applications and is capable of forcing the thermowell into resonance with the possibility of fatigue failure not only of the thermowell but also of the temperature sensor. The conditions for flow-induced resonance generally govern the design of the thermowell apart from its pressure rating … WebbFlexible selection of immersion length and thermowell geometry according to the process specifications.
