In Europe, the metrological connection needs in force are not covered beyond 15 MN. This corresponds to industrial applications in many fields (mechanics, construction, energy). The needs are estimated up to 50 MN.

Objectives

Extending the range of force measurements above 15 meganewton

Consolidate force measurement uncertainties with force pyramid benches

Improve the calibration control of multi-component sensors

The stability of atomic clocks operating in the optical domain is currently limited by two factors: the frequency noise of the laser used to probe the atomic system and the quantum projection noise, which intervenes when the state of this system is detected. This European QESOCAS project addresses these factors that limit uncertainties at the 10-18 level. These studies could have an impact on most clock applications and open the possibility of new applications.

Objectives

Using quantum entanglement to improve the metrological performance of optical clocks and atomic sensors

The electrical grid is currently undergoing profound changes throughout the world. Indeed, the current supply networks, which are centralised and incorporate a large share of fossil fuel power plants, must migrate towards an increased integration of renewable energy sources (RES). The energy landscape is therefore evolving towards diversified and decentralised production.

Objectives

The general objective of the European project is the development of a metrological infrastructure, so as to successfully implement a smart electrical grid in Europe

The objective of the associated RNMF project is the realization of a reference PMU that can be used for on-site measurements and laboratory tests

Currently temperature measurements are traceable to the 1990 International Temperature Scale (ITS-90) or the 2000 Provisional Low Temperature Scale (PLTS-2000) below 1 K. These scales have an empirical basis and are based on a series of fixed points whose temperatures have been determined a priori by primary methods.

Objectives

Extension of primary thermometry

The International Temperature Scale 1990 (ITS-90) is the current internationally recognized temperature scale in use worldwide. After the redefinition of the kelvin via the Boltzmann constant, the ITS-90 will continue to be used as a robust and reliable tool. However, it has some limitations and pending issues that need to be resolved.

Objectives

Development of new advanced techniques to improve the traceability of the current definition of the kelvin, before the redefinition of 2018

Establish traceability to the SI according to the new definition, in order to support the widest and simplest dissemination of the temperature unit to end users
