TEF 31


The here listed thermocouples are mainly customized designs. If you have any queries regarding temperature recording we are more than happy to assist you here. We manufacture form single items up to high volume. Ask us for your temperature sensor!

Screw-in thermocouples are very suitable for surface measurements. They are screwed direct into the component and are available in various diameters and thread sizes. The small TEF 31 sensor diameter offers a fast reaction. The TEF 31 has a 7 mm key size and is therefore easily to screw into the component.
