UK Manufactured Rare Metal Thermocouples
We manufacture and design rare metal thermocouple assemblies. Rare metal thermocouples are made from conductors containing platinum and rhodium alloys and are suited for measuring high temperatures up to +1700°C. They are a rugged design, suited for tough industrial use.
Rare Metal Designs
The rare metal sensor will need contamination protection from the process it is measuring. Each thermocouple should have a protection sheath best suited to its application.
Common designs are:
If you are unsure exactly what you need, get in touch and we can help identify your requirements.
Rare Metal Thermocouple Assembly with Ceramic Sheath
The sensor can be protected by a ceramic sheath. There are a variety of ceramic sheaths available each with its own properties.
Rare Metal Thermocouple Assembly with Metal Sheath
The sensor can be protected by a stainless or metal alloy sheath. These types of designs are often used in cement works or incinerators.
Rare Metal Thermocouple Assembly with Platinum Thimble
The sensor can be protected by a ceramic sheath with a platinum thimble at the hot end. This design is often used in container glass forehearths to take uniformity measurements but can be applied to other applications if suitable.
Rare Metal Thermocouple Assembly with Full Platinum Thimble
If required the sensor can be protected by a full length platinum thimble. It is a more robust design of the Rare Metal Thermocouple Assembly with Platinum Thimble.
Rare Metal Thermocouple Types
There are three types of rare metal thermocouple all made from alloys of platinum and rhodium with slightly different characteristics and specifications.
Type R & Type S Thermocouple
UK and European Standard.
Type B Thermocouple
Very high max temperature.
All our rare metal thermocouples are custom made, as such we are able to tailor your sensors exactly to your requirements. There are many options available including:
We’ve made rare metal thermocouples for over 15 years and today we are considered the best choice for custom built temperature sensors in the UK. We continue to apply our expertise and invest in the latest technology to provide our customers with the highest quality temperature sensors available.
