Mineral insulated sensors

For extreme temperatures and harsh environments, for maximum protection and reliability.

Advanced Mineral Insulated Temperature Sensors:

MI sensors are built for applications where standard sensors fall short. Whether operating in high-vibration environments, areas with elevated moisture exposure or installations requiring marine-approved solutions, mineral insulated sensors deliver the protection and measurement integrity your application demands.

  • Wide range of MI sensors for many different applications
  • High degree of protection against moisture
  • Vibration proof
  • Marine approval for selected sensors
  • For maximum accuracy we recommend 4-wire

Mineral Insulated Temperature Sensors: Accuracy from -270°C to 1600°C

Our mineral insulated temperature sensors feature both thermocouples and resistance thermometers. MI sensors are normally used for temperature measurement between -270°C / -454°F and 1600°C / 2912°F, depending on sheath material and choice of element.

Long-length sensors, especially for low-temperature applications, also typically require mineral insulated sheaths to avoid joints and ensure best conductivity.

Flexible Mineral Insulated Temperature Sensors

Depending on the application, mineral insulated temperature sensors are available in 2-wire, 3-wire, 4-wire, simplex and duplex configurations.

The sensors are manufactured in different sheath materials and dimensions, with compressed Magnesium Oxide (MgO) powder inside to ensure excellent thermal conductivity and an airtight environment against moisture.
