In industries where temperature measurement is necessary, such as the food & drink and automotive sectors, most of the 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.
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.
Thermowells provide an invaluable service and offer several 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
There are several materials that can be used to make a thermowell, but in order to guarantee the best protection, several 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?
We believe FEP is the ideal material for encapsulating a thermowell, harbouring a number of beneficial properties.
High impact strength
Useful in all environments our 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, our 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.
