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.

If you are unsure exactly what you need, get in touch and we can help identify your requirements.
MI Thermocouple with Pot Seal & Flexible Tails
A very common robust sensor with a wide range of applications. Also known as “bare leads” thermocouple.
Mineral Insulated Thermocouple Insert with Block
This standard design can be altered in accordance with IP65 and is very suitable for insertion into a pocket.
Mineral Insulated Thermocouple with Standard Plug
The standard plug enables the temperature sensor to be easily connected and disconnected to a variety of controllers and readouts in busy and demanding environments.
Mineral Insulated Thermocouple with Miniature Plug
The miniature plug enables the temperature sensor to be easily connected to a variety of hand held instruments and read outs.
Mineral Insulated Thermocouple with Head
This standard design can be altered in accordance with IP65 and is very suitable for insertion into a pocket.
MI Thermocouple with Permanently Attached Cable
This is a variation on the MI Thermocouple with Pot Seal & Tails. It comes with a longer cable and is often used in original equipment manufacture.
Mineral Insulated Thermocouple With Transmitter
This design is suitable for insertion into an existing thermowell assembly.
Mineral Insulated Thermocouple Insert with DIN Plate
This standard design can be altered in accordance with IP65 and is very suitable for insertion into a pocket.
Mineral Insulated Thermocouple with Basic Seal
This standard design can be altered in accordance with IP65 and is very suitable for insertion into a pocket.
