The patented WIKA V-PAD enables the surface temperature of a pipe 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 welded connection to be made between the sensor and the pipe. 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. At one end of the sheathed cable, the internal leads are welded together. For the versions with a non-insulated(grounded) measuring point, the sheath is welded to the thermocouple. At the other end of the sheathed cable the ends of the leads are connected and the sheathed cable is hermetically sealed using a sealing compound. The lead ends form the platform for the electrical connection. Cables, plug-in connectors or connector sockets can be connected to them.
The pipe surface thermocouple is supplied with a non insulated measuring point (grounded). Only in this way it is possible to ensure that the temperature-sensitive measuring point is positioned as close as possible to the pipe surface. By welding the V-PAD, the measuring point is, thus, a part of the pipe surface and provides the most-accurate measurement results.
