What is a Mineral Insulated Thermocouple?

A mineral insulated thermocouple is a temperature-sensing device consisting of thermocouple wires encased in a stainless steel metal sheath filled with compacted mineral insulation, typically magnesium oxide. The hot junction forms the critical measurement point where accurate temperature detection occurs.

What are the Advantages of a Mineral Insulated Thermocouple?

This design offers several advantages:

1. Durability: The metal sheath protects the internal wires from physical damage and harsh environments.

2. Flexibility: Despite its robust construction, it remains flexible, allowing for installation in tight or curved spaces.

3. High-temperature resistance: The mineral insulation allows for use in extreme temperatures.

4. Fast response time: The compact design enables quick temperature readings.

5. Electrical isolation: The mineral insulation provides excellent electrical insulation between the wires and the sheath.

6. Moisture resistance: The sealed construction prevents moisture ingress, enhancing longevity.

7. Versatility: Available in various diameters, lengths, and thermocouple types to suit different applications.

8. Stability: The design minimises drift and ensures consistent readings over time, supporting accurate calibration requirements.

These features make mineral insulated thermocouples ideal for use in challenging industrial environments, scientific research, and high-precision temperature measurement applications.

We Manufacture Mineral Insulated Thermocouples in the UK

We specialise in creating and developing mineral insulated thermocouples, which are comprised of an external metal sheath safeguarding the thermocouple components from harm and impurities.

This pliable sheath allows for easy bending and shaping to accommodate diverse applications. The internal thermocouple elements are encased in densely packed magnesium oxide powder, ensuring optimal thermal conductivity without trapped air.
