Electrical temperature measurement Tubeskin thermocouple assembly Model TC59-V WIKA data sheet TE 65.59 further approvals see page 7 V-PAD Applications Chemical industry Superheated steam applications Refineries Heating furnaces and high-performance boilers Heat exchangers 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 V-PAD tubeskin thermocouple, model TC59-V Description The patented WIKA V-PAD enables the surface temperature of a tube 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 tube. 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. The lead ends form the platform for the electrical connection. Cables, plug-in connectors or connector sockets can be connected to them. Sensor design The tubeskin thermocouple is supplied with a non-insulated measuring point (grounded). Only in this way it is possible to ensure that the temperaturesensitive measuring point is positioned as close as possible to the tube surface. By welding the V-PAD to the tube, the measuring point becomes part of the tube surface and provides accurate measuring results. At one end of the sheathed cable, the internal leads are welded together to form a non-insulated (grounded) measuring point. 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.

These specialists utilise best practices derived from scientific properties to optimise the life and accuracy of the thermocouple. They make suggestions to optimise the system for temperature, movement, and burner firing. Some design considerations that can help determine measuring points for the specific application in order to choose the best suitable product: Expansion loops Expansion loops should be designed to account for maximum tube movement from startup position to operating temperature. Loops should be designed in accordance with allowable space available. Examples of expansion loops: S-loop Material compatibility with furnace tube Heat transfer (radiation, convection, conduction) Junction (grounded, ungrounded) Thickness of the mineral-insulated cable (flexibility vs. durability) Expansion loops (location and design) Flame impingement Furnace exit design options Burner fuel (flue gas composition) Welding procedure (TIG, stick, temperature monitoring) Mounting (location, orientation) Operating vs. design temperatures Bending radius Path to furnace wall Tube clips (location and routing) Connection head (material, location, approvals) Furnace design (burner locations) Single coil Multiple coil Spiral loop Page 5 of 7

ASTM E230 Thermocouple type Positive leg Negative leg K Yellow Red J White Red E Violet Red N Orange Red Explosion protection (option) Thermocouples of the TC59 series are available with an EC-type examination certificate for intrinsically safe, Ex i, ignition protection. These instruments comply with the requirements of 94/9/EC (ATEX) directive for gas and dust. For all instrument variants of TC59-V the thermocouple is grounded welded. The intrinsically safe circuits are galvanically connected to the earth potential. The classification/suitability of the instrument (permissible power, P max, as well as the permissible ambient temperature) for the respective category can be seen on the EC-type examination certificate and in the operating instructions. Built-in transmitters have their own EC-type examination certificate. The permissible ambient temperature ranges of the built-in transmitters can be taken from the corresponding transmitter approval. The internal inductance (L i ) and capacitance (C i ) for cable probes are found on the product label and they should be taken into account when connecting to an intrinsically safe power supply. Thermocouples of the TC59 series are also available with a CSA or FM certificate, Class I Division 1 or Class I Division 2 depending on the style. For assemblies supplied with a WIKA termination head and flame path, Class I Division 1 may be applicable. For assemblies supplied with a WIKA termination head and flexible armour, Class I Division 2 may be applicable. Consult WIKA for your explosion protection requirements. Page 6 of 7
