Description of the tubeskin thermocouple

The patented WIKA V-PAD® enables the surface temperature of a tubeskin thermocouple within a combustion furnace to be measured accurately. The name V-PAD® is derived from the shape of the sensor. It is V-shaped and enables a full penetration welded connection to be made between the sensor and the tubeskin thermocouple. 

In the V-PAD®, the flexible part of the sensor is a mineralinsulated cable (sheathed cable). It consists of a metal outer sheath, which contains the insulated internal leads, compressed within a high-density ceramic composition. The internal leads are made from thermo material. The material of the outer sheath can be selected to match the application.
