Mineral Insulated Thermocouples
Learn more about our Mineral Insulated Thermocouples
UK Manufactured Mineral Insulated Thermocouples
We manufacture and design mineral insulated thermocouples. Mineral insulated thermocouples consist of an outer metal sheath which protects the thermocouple elements from damage and contamination, this sheath is malleable so mineral insulated thermocouples can be easily bent and formed into a variety of shapes to suit your application. The inner thermocouple elements are insulated with magnesium oxide powder, tightly packed so no air is trapped inside, this provides great thermal conductivity.
Wide variety in designs and uses
MI Thermocouples are very tough and can withstand up to 1250°C (depending on design and thermocouple type) making them perfect for a wide variety of industrial uses such as ovens, kilns and furnaces.
There are a wide range of options for our MI thermocouples. They can be constructed with various diameters and materials of sheath, many different thermocouple types and with our laser welder, mineral insulated thermocouple lengths are practically limitless.

Common Designs Are:
All our thermocouples are custom made, as such we are able to tailor your sensors exactly to your requirements. There are many extra options available including:
Materials which would work best in your process are available on request.
Flange or compression fittings can be added such as an adjustable or welded flange on shank.
Full UKAS or UKAS traceable calibration is available. AMS 2750 F to full or traceable calibration is available.
Duplex & Triplex
Thermocouples can be supply duplex or triplex instead of simplex.
Material certificates are available on request.
Reduced tip options
Reduced hot junction for fast response or cost saving.
High Temperature Versions
High temperature options for plugs, sockets and cable can be supplied.
Your own serial, product number or other information attached to sensors via heat shrink cable or metal tags.
Thermocouple junctions can be insulated, exposed or grounded depending on what’s suitable for your application.
Bent to shape
MI thermocouples can be bent to any shape to fit your process or application.
We’ve made mineral insulated thermocouples for 25 years and today we are considered the best choice for custom built temperature sensors in the UK. We continue to apply our expertise and invest in the latest technology to provide our customers with the highest quality temperature sensors available.
