Michele Scervini is a research scientist at the Department of Materials Science and Metallurgy of the University of Cambridge, where he is working on materials for thermocouples along with Dr Cathie Rae.
Thermocouples are currently the most commonly used temperature sensors due to the wide range of temperatures they are able to operate at, which spans from cryogenic temperatures to very high temperatures.
The main aim of Michele's research is the improvement of the temperature capability of thermocouples for gas turbine applications and nuclear applications, which is currently limited to about 1000°C. In particular Michele is focused on the metallurgical modifications occurring in thermocouples during operation; the time-dependent degradation of the physical and chemical properties of the materials the thermocouple is made of can produce significant errors in the temperature measurement: this phenomenon is called drift.
A better understanding of the causes of drift can result in the design of:
- reduced drift thermocouples,
- drift-less thermocouples.
In order to achieve this result Michele is working on both traditional type K thermocouples and new materials for thermocouples.
Michele's work has been funded in the past as part of HEATTOP, a European project where European industrial partners and European Universities develop sensors for gas turbines. The HEATTOP project was funded by the European Community as part of the Sixth Framework Programme (FP6).
He has later worked as part of METROFISSION, a European project where Michele has studied and developed thermocouples for nuclear applications. Metrofission was funded by the European Metrology Research Programme (EMRP).
Currently Michele is working on thermocouples for gas turbines as part of the project STARGATE, a European project where European industrial partners and European Universities develop sensors for gas turbines. The STARGATE project was funded by the European Community as part of the Seventh Framework Programme (FP7).
