TC59-V Tubeskin Thermocouple

Special features

Engineered block design
Application ranges from 0 … 1,260 °C (32 … 2,300 °F)
Flexible sheathed cable, mineral-insulated internal leads
High mechanical strength, shock resistant

Sensor design

The tubeskin thermocouple is supplied with a non-insulated measuring point (grounded).

Only in this way is it possible to ensure that the temperaturesensitive measuring point is positioned as close as possible to the tube surface. The measuring point becomes part of the tube surface and provides accurate measuring results by welding the V-PAD^® to 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.

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

The internal leads are welded together to form a non-insulated (grounded) measuring point at one end of the sheathed cable. The other end 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.
