Thermocouples by Peak Sensors

Peak Sensors manufactures and supplies a wide range of thermocouples designed for precise and reliable temperature measurement across various industries. All sensors are made in the UK, tailored to suit demanding environments and applications.

Thermocouple Types

Rare-Metal Thermocouples Types R, S, and B are designed for high-temperature and oxidising environments. These are available with either metal or ceramic protection sheaths and are commonly used in industries such as glass, metals, and ceramics.

Base-Metal Thermocouples Types K, J, T, E, and N are general-purpose sensors suitable for a wide range of temperature monitoring tasks. These are available in both metal and ceramic sheaths.

Mineral-Insulated Thermocouples These feature a metal sheath filled with compacted insulation, offering excellent durability and fast response. They are ideal for harsh conditions and high-accuracy applications.

Cable Thermocouples Flexible and easy to install, cable thermocouples are insulated with materials like PVC, PTFE, or glass fibre, making them suitable for many industrial uses.

Thermocouple Inserts and Elements Available for use inside thermowells or as part of custom assemblies. These inserts are ideal for replacing elements without removing the entire sensor.

Hand-Held Thermocouples Designed for portability, these sensors are commonly used for maintenance, testing, and inspection tasks.

Custom and OEM Solutions

OEM Temperature Sensors Peak Sensors designs and manufactures high-volume, custom sensors for OEMs. These sensors are developed to fit seamlessly into your equipment and production processes.

Custom-Built Thermocouples If your application is unique, custom thermocouples can be designed for specific needs, including multi-point, surface-mount, compost, and exhaust gas measurements.

Additional Services

Calibration A full calibration service is available, including UKAS-accredited options, to ensure your sensors deliver traceable and accurate results.

Platinum and Rhodium Recycling Old sensors containing platinum or rhodium can be returned for precious metal recovery, helping to reduce waste and control costs.

Sensor Repair and Replacement Repair services are available to extend the life of your sensors, alongside replacements for outdated or worn-out components.

On-Site Temperature Surveys Engineers can visit your site to assess process temperatures and provide thermal performance diagnostics.
