They are used to provide an isolation between a temperature sensor and the environment, either liquid, gas or slurry.

Thermowells are recommended whenever a temperature element is to be inserted into a process where corrosion, pressure, abrasion, or shear forces may threaten the life of the element. In addition, thermowells allow for a defective instrument to be removed without shutting down or draining the process.

There are three broad categories of thermowells:

  • Screwed
  • Flanged
  • Weld-in

They can be designed to accept:

  • Thermocouples
  • RTDs
  • Temperature Gauges
  • Filled systems

Standard thread forms are BSP and NPT (others available to order), and flange size and rating can be supplied to suit any requirement.

Thermowells can be machined from solid barstock, or fabricated from pipe:

  • Barstock thermowells are suited to high pressure applications.
  • Fabricated thermowells offer a lower cost alternative where high pressure is not a design consideration.

Where there is a requirement to measure the temperature of highly corrosive processes, Pyrosales can provide a thick teflon sleeve which covers all the wetted parts of the thermowell.

Teflon is an ideal material if the temperatures are not high as it is resistant to most strong acids. With a Teflon sleeve, you can protect your sensor and maintain control of your process temperature.
