FEP coated thermowells

Here at Adtech, we use a variety of technologies and materials to encapsulate temperature sensors.

In industries where temperature measurement is necessary, such as the food & drink and automotive sectors, the majority of consideration is given to the type of temperature sensor that will be used and not how to protect it. This is where our FEP coated thermowells can help.

What is a thermowell?

A thermowell is a component which is designed to surround a temperature sensor, working to protect it from any harsh process conditions, such as chemicals and high temperatures. A thermowell is permanently mounted into a piece of pipe and the temperature sensor is inserted inside when necessary. Though an often forgotten about accessory when it comes to temperature management, if you emit to using a thermowell it is very likely that the sensor will become damaged and have a lesser life span as a result.

Benefits of FEP coated thermowells:

There are a number of materials that can be used to make a thermowell, but in order to guarantee the best protection, a number of questions must be considered to help you decide.

  • Will the thermowell be able to withstand the very high/low temperatures?
  • Will the thermowell deteriorate during the process?
  • Will the thermowell be strong enough to resist high impact forces?
  • Will the thermowell respond to changes in temperature at a satisfactory speed?

Here at Adtech, our FEP is the ideal material for  encapsulating a thermowell, harbouring a number of beneficial properties, such as:

  • Chemical resistance
  • Weather resistance
  • High impact strength
  • Non-stick coating
  • Thermal functionality
  • Useful in all environments

Why are thermowells necessary?

Thermowells provide an invaluable service and offer a number of benefits to the temperature measurement process:

  • Protection against damage from excessive pressure, material velocity and corrosion
  • Increased lifespan to the temperature sensor
  • Allow temperature sensor replacement without the need to drain the system
  • Reduced amount of contamination

All of Adtech’s FEP coated thermowells are available with FDA approval, in any length, with diameters ranging from 1mm to 50mm.

For applications with more complex shapes and the need for a faster temperature response, Adtech’s spray coatings, available in PVDF and PTFE, are advantageous.

As it is often valuable to include the sensor element in the thermowell, we offer a complete assembly service, sourcing all components where necessary.
