What is a Mineral Insulated Probe?

Mineral insulated probes are made from mineral insulated cable. It has a metallic outer jacket and on the inside, the conductors are insulated with densely packed magnesium oxide. This construction bears a lot of advantages for temperature sensors.

Characteristics of Mineral Insulated Probes

A mineral insulated thermocouple has an extremely wide temperature range: from below -200 °C up to more than 1,100 °C. Furthermore, mineral insulated probes are resistant to vibration and scratches which proves their longevity. At the same time, they are bendable. Surprisingly, they are affordable as well: MI cable costs about the same as fiberglass cable. We manufacture MI probes in diameters from 0.25 mm up to 20 mm. To ensure maximum water tightness, we mould either a connector or a robust cable transition onto the probe.

Which Sensing Element Should You Choose?

Your choice of sensing element depends on your application and requirements. Our mineral insulated RTD (Pt100 and Pt1000) can withstand temperatures between -50 and 500 °C. For higher temperatures, type K thermocouples are a good choice. In the plastics industry, type J thermocouples remain a popular option.

Suggestions when using MI Probes

We have a comprehensive range of mechanical accessories for our mineral insulated probes that enables you to mount the probe in your preferred way. Tip adapters, bayonet fittings, and compression springs are just a few examples.

As with all types of temperature sensors, the immersion length should be min. 5x the diameter of the probe in order to avoid thermal bridges. 

Regarding the response time of a probe, consider this rule of thumb: if you double the diameter, you quadruple the response time. Additionally, the price increases with diameter. Oftentimes you are better off choosing a smaller diameter and combining it with a tip adapter. As a bonus, this will also improve the performance of the probe.
