Type N Thermocouple Manufacture

We manufacture type N thermocouples to your specifications or as replacements to existing sensors. We have manufactured thermocouples for over 15 years and are solely focused on the design and manufacture of temperature sensors. Please call or email us to discuss your requirements.

Type N Thermocouple Designs

Thermocouples can come in a variety of designs suited to different applications. View the details of each type of design we offer for Type N.

Mineral Insulated Type N – Metal sheath insulated with magnesium oxide powder also called MIMS.
Cable/Wire Type N – Flexible sensors in PVC, PTFE or Glass Fibre. Many cold and hot-end designs.
Type N with Ceramic Sheaths – High temperature design with ceramic protection sheath
Type N with Metal Sheaths – High temperature design with metal protection sheath
Type N Inserts – Rigid metal tubes commonly used in pocket, thermowell or head assemblies.
Type N Elements – Basic elements for further assembly into sheaths or equipment.

Thermocouple Type N Technical Details

Type N is a relativity new thermocouple type that was made to be an alternative to Type K. It has high stability over time but is more costly than type K at similar temperature ranges. Its sensitivity is about 39 µV/°C, slightly lower compared to type K.
