CCPI Europe is happy to announce that it has signed the license agreement with UK’s National Measurement Institute (NMI), the National Physical Laboratory (NPL), for the self-validating thermocouple or INSEVA.

 

On the 15th May 2018, representatives from CCPI Europe visited NPL (Teddington, UK) to formally sign this exclusive licence agreement for the new revolutionary INSEVA (Integrated Self-validating thermocouple) technology.

This state of the art, new technology operates by employing the same principles as used in thermal calibration laboratories for the highest level of calibration, i.e. the fixed-point method of calibration.

The reliable melting/freezing point of pure metal and more recently metal carbide eutectics, are used to calibrate thermocouples at set fixed point temperatures.

Copper, for example, freezes (goes through the transition from a liquid to a solid) at 1084.62 °C

The “INSEVA” thermocouple incorporates the fixed-point calibration techniques, so a calibration on the thermocouple in situ reading can be made when required, while still behaving like a conventional thermocouple assembly.

As the environment temperature passes through the fixed-point melting/freezing point of the material, the thermocouple voltage reading ‘hesitates’ as it transits the melting/freezing point of the material. The reading from the thermocouple can be then checked against the temperature, as the true temperature can be determined from the melting/freezing point of the material, and a measurement can be made which can be used to account for the calibration accuracy / drift of the thermocouple.

Jonathan Pearce, Principal Research Scientist and head of contact thermometry at NPL, said:

“I am very pleased that CCPI Europe are taking this technology forward, and I am confident that it will lead us further towards the goal of traceable in-process reference standards for reliable industrial temperature measurements. As early adopters who are open to new ideas and are capable of following them through, CCPI Europe should be able to implement the new sensing methodology in a way that is accessible to a broad base of end-users.”

Jonathan Golding, Managing Director of CCPI Europe, added,

“CCPI Europe is honoured and delighted to be have been selected by NPL to take this technology forward. CCPI Europe; a Marmon Engineered Wire & Cable Company / Berkshire Hathaway organisation, is well positioned to promote this new technology across multiple industries and corresponding applications. Our depth of application knowledge and industry ties in heat treatment and thermal processes around the world, now with the support of the NPL team, will allow CCPI Europe to refine this technology in cooperation with forward-thinking customers”
