K-Type Surface Thermocouple Probe

Fast surface temperature measurement with a lug-mounted probe

This K-type surface thermocouple is designed for measuring the temperature of flat surfaces, plates, pipes and machine parts where a standard immersion probe cannot be used. The cold-pressed lug is screwed or bolted directly to the surface, and the pierced hole makes installation quick and repeatable.

The sensing junction sits in a thin metal lug, so heat transfers from the surface into the junction with very little lag. That makes the probe suitable for packaging machines, bearing housings, motors, platens, heat exchangers and other applications where a fast surface reading matters more than measuring the air around the part.

Construction and options

• Element: Type K standard; Type T, J and Pt100 versions are also available in this product family.
• Mounting: cold-pressed lug with a pierced hole for a screw or bolt.
• Lead length: 0.5 m, 1 m, 1.5 m, 2 m and 3 m standard; custom lengths on request.
• Lead and insulation: selected to suit the temperature and environment; tell us if you need PTFE, fiberglass or another insulation.
• Termination: bare wire standard; connectors and extensions can be quoted.

Typical applications

Packaging and sealing machines, bearing and gearbox housings, motor frames, heated platens, moulds, heat exchangers and HVAC equipment.
