Important results from the project
As part of the project National Mertology Institute (NMI) for force and torque has developed a traceability chain for continuous force measurements - those for which the increase or decrease of the load changes continuously over time. Moreover, the technical competence in this area has increased significantly, along with the development of resources. This makes it possible to introduce a new calibration service for continuous forces at NMI for force and torque and offer it for Swedish and international community.
Expected long term effects
NMI for force and torque has developed the traceability chain for continuous force measurements as well as the calibration procedure, more suitable for various industrial applications. This allows to apply for international recognission in this area and the confirmation of measurement capabilities as well as technical competences is planned by performing comparative measurements and publishing the results. Doing so will result in an implementation of new force calibration services in NMI for power and torque.
Approach and implementation
A detailed study of loading rates as well as series of tests and investigations proved that RMP for force and torque has resources and capabilities to carry out continuous force calibration services. Comprehensive work on measurement data analysis and development of compensation techniques shows that the existing instrumentation allows to perform continuous calibration of force measuring instrument with measurement uncertainty 0.8 % of the measured value. However, further development and improvement of resources and methodology makes a possibility to reduce it even to 0.1 %.
