WIKA Gayesco TC59-X XTRACTO-PAD Tubeskin Thermocouple Assembly

The XTRACTO-PAD® provides accurate temperature measurement of combustion furnace tube.

The XTRACTO-PAD® is a thermocouple design utilizing a guide channel and patented heat shield. A removable contoured thermocouple sensor made from mineral-insulated cable (sheathed cable) is installed in the guide channel and heat shield. 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 to form an insulated (ungrounded) or non-insulated (grounded) measuring point.

This unique thermocouple design allows for weldable parts (guide channel, heat shield, and tube clips) to be installed by the manufacturer of the heater/boiler or even by the tube manufacturer in the case of specialty furnace tubes.

• Weld pad attached to a guide channel, heat shield
• Removable thermocouple design, so thermocouple can be replaced without any additional grinding, welding, or inspection
• Allows for welded parts to be attached without the presence of the sensor
• Weld pad, guide channel, heat shield and clips can be installed by the heater/boiler manufacturer, or by a specialty tube manufacturer
• Special features help improve reliability of temperature readings
• Application Criteria:
  • For use with catalytic reformers, steam methane/naphtha reformers and reaction furnaces
  • Designed for high heat flux or difficult applications, up to and including flame impingement
  • Weldable parts can be sent to furnace or tube manufacturer for initial installation
  • Patented shielded design ensures reliable readings, even in harsh environments
  • Grounded or ungrounded junction
  • Radial or longitudinal mounting onto tube
