GENERAL CLASSIFICATION OF THE ELECTRICAL METHODS FOR MEASURING MECHANICAL QUANTITIES

Dan Mihai Ştefănescu

Abstract

The main purpose of the paper is to outline the essential properties, principal classes and most widely used principles / methods / approaches typical for the modern instrumentation in the area of electrical measurement of force and related quantities (such as torque, pressure, strain, vibration). For beginning, the concepts of <i>sensor</i> and <i>transducer</i> are clarified, emphasizing that the sensor is the element being influenced by the measurand, while the transducer is usually a more complex device performing the input-output conversion. A general classification of the <i>electrical methods</i> for measuring mechanical quantities is proposed, comprising 12 basic plus two additional classes. Another classification is given for twelve types of <i>elastic elements</i> of force transducers. Finally, a few typical examples are chosen to illustrate the domains of the TC3 (Force, Mass and Torque), TC5 (Hardness) and TC22 (Vibration), jointly organizing this IMEKO conference in Cape Town, Republic of South Africa.
