Description

The V-PAD ® model TC59-V provides accurate and reliable temperature readings of process tubes inside combustion furnaces. Through extensive testing at WIKA's R&D centre in Houston, Texas, the V-PAD ® has been designed to provide unmatched accuracies in varying process conditions.

At the heart of the V-PAD ® thermocouple is a patent pending V-shaped block designed to enable a full penetration weld between the sensor and the process tube. The flexible part of the sensor is a mineral-insulated metal-sheathed cable. It consists of a metal outer sheath which contains the insulated internal thermocouple conductors compressed within a high-density ceramic composition. The materials of the thermocouple can be selected to match the application.

Inside the V-PAD ® block, the internal conductors are welded together to form a non-insulated (grounded) measuring point. The other end of the mineral-insulated metal-sheathed cable provides a hermetically sealed platform for the electrical connection. Cables, plug-in connectors, or connector sockets can be connected here.
