High Temperature RTDs & Thermocouples

Mineral Insulated (MI) temperature sensors are robust, flexible, fireproof, can be made in long lengths and with a broad range of diameters. Many sensor types including Thermocouple calibrations K, T, J, N and RTD calibrations Pt100/Pt1000 RTD are available with various cold end options. The cable is also very easy to handle which makes it ideal for installing in to applications with limited space or where access is difficult.

Mineral Insulated RTDs have better flexibility, repeatability and long term stability.

Mineral Insulated Thermocouples have a wider temperature range, rapid response, and longer conductor life.

The Mineral Insulated Temperature Sensors we manufacture are available with a wide range of terminations such as lead wires, transmitters, plugs or industrial head assemblies to suit a wide variety of applications. Whatever your needs, Sterling Sensors will be able to provide an MI for your application.
