Tubeskin thermocouples

High-quality tubeskin thermocouples from WIKA

The purpose of tubeskin measurement is to determine tube service life, monitor trending, and provide safeguards within a plant. By relying on accurate tubeskin sensors, clients can achieve increased tube service life and optimised production within heater operations at their plant. WIKA’s tubeskin product portfolio includes the REFRACTO-PAD®, V-PAD®, XTRACTO-PAD® and WELD-PAD thermocouples; and each solution is engineered to fit your application. Along with these tubeskin products, WIKA also provides installation services as a key component to a successful tubeskin solution.


Why would I use a tubeskin thermocouple?

Temperature measurement in heaters or furnaces is extremely important and the tubeskin thermocouple is one of the best ways to determine if the temperature is in the right range.

Do I need expansion loops?

If you anchor a tubeskin thermocouple outside the furnace (fixed exit) and have any furnace tube movement you will need expansion loops. There are various expansion loops used such as S-loop, multiple coil, single coil and spiral loop.

In order to replace an XTRACTO-PAD® (model TC59-X) assembly do I need to buy all the accessories?

No. The tube clips, guide tube with weld-pad and the heat shield will be reused. Only the sensor element needs to be replaced. No welding is required.
