Thermocouples

Thermocouples & Adaptors

Our extensive range of thermocouples and resistance temperature detectors (RTDs) is designed to suit a wide variety of industrial heating and sensing applications. From simple surface-mounted probes to precision bayonet assemblies, we manufacture bespoke temperature sensors in a wide range of styles, diameters, and materials.

We offer all standard thermocouple types including Type J (Iron/Constantan), Type K (Chromel/Alumel), and Type T (Copper/Constantan), as well as 2, 3, and 4-wire PT100 resistance probes. Customisable features include electrically isolated junctions, duplex configurations, thermal insulation, and mineral-insulated construction for high-performance applications.

Available with metal braided or PTFE-insulated cables in virtually any length, our sensors can be supplied with fitted miniature or standard plugs and sockets. Threaded adaptors for bayonet-style sensors are available in multiple sizes and thread types, enabling secure and accurate installation.

Additional options include terminal head assemblies, melt pressure versions, and a wide variety of mounting configurations for compatibility with your process requirements.
