Thermowells are cylindrical pressure-tight fittings used to protect the temperature sensors such as Thermocouple and RTD, which are inserted into a pipe or vessel in industrial applications. It protects the sensing element against corrosive process media and fluid pressure and velocity.
Thermowells find wide applications in many industrial sectors including Steel, Cement, refining, cosmetics, petrochemical, food processing, chemicals, Power, pharmaceutical, and other process industries.
Thermowells play a crucial role in the successful measurement of temperature in industrial processes.
Material selection of thermowell will depend on the chemical, temperature and flow rate of the process fluid. With an increase in temperature and fluid concentration, the corrosive effects of chemicals normally increase.
Let's see the selection of a thermowell:
1. The key parameters to consider while selecting a thermowell are:
2. Insertion Length
3. Immersion Length
4. Lagging Extension Length
5. Thermowell Process Connection Length
6. Thermowell Length
