Handbook of Force Transducers (eBook, PDF)

Principles and Components

Beschreibung

Part I introduces the basic "Principles and Methods of Force Measurement" according to a classification into a dozen of force transducers types: resistive, inductive, capacitive, piezoelectric, electromagnetic, electrodynamic, magnetoelastic, galvanomagnetic (Hall-effect), vibrating wires, (micro)resonators, acoustic and gyroscopic. Two special chapters refer to force balance techniques and to combined methods in force measurement.

Part II discusses the "(Strain Gauge) Force Transducers Components", evolving from the classical force transducer to the digital / intelligent one, with the incorporation of three subsystems (sensors, electromechanics and informatics). The elastic element (EE) is the "heart" of the force transducer and basically determines its performance. A 12-type elastic element classification is proposed (stretched / compressed column or tube, bending beam, bending and/or torsion shaft, middle bent bar with fixed ends, shear beam, bending ring, yoke or frame, diaphragm, axial-stressed torus, axisymmetrical and voluminous EE), with emphasis on the optimum location of the strain gauges. The main properties of the associated Wheatstone bridge, best suited for the parametrical transducers, are examined, together with the appropriate electronic circuits for SGFTs.

The handbook fills a gap in the field of Force Measurement, both experts and newcomers, no matter of their particular interest, finding a lot of useful and valuable subjects in the area of Force Transducers; in fact, it is the first specialized monograph in this inter- and multidisciplinary field.

Autor

Dan Mihai ¿tef¿nescu, born in Bucharest on 6 April 1946, received BS (1969) in Applied Electronics, MS (1983) in Experimental Stress Analysis and PhD cum laude (1999) in Electrical Engineering, all from the "Politehnica" University of Bucharest. He worked as Senior Researcher in Measurement Techniques with the National Institute for Aerospace Research in Bucharest (1969 - 2003). He completed a Postdoctoral Fellowship (NATO grant) on Knowledge-based Intelligent Systems for Selecting Industrial Sensors at Twente University of Enschede, The Netherlands (2002). He was Visiting Scientist within Korean Research Institute of Standards and Science, conducting a project on Force Transducers Optimization by Numerical Methods (2004) and then within Center for Measurement Standards in Taiwan, R.O.C., leading a project on Improved Portable Truck Scales (2005). Now, he is Senior Consultant for the Romanian Measurement Society. His current research interests: electrical measurement of mechanical quantities, material testing installations and metrological procedures for multicomponent transducers. He delivered 46 conferences and published 4 books, 2 book chapters and 192 papers in 40 countries on all continents (minus Antarctica). He is member of the Verband Deutscher Electrotechniker (1987) and Romanian representative (1988) as well as member of the General Council of IMEKO - International Measurement Confederation (2015).
