Mechanical measurements and instrumentation Unit One

Measurement and its significance

Measurement and its significance, methods of measurement –direct methods and indirect methods and classification of measurements –primary measurements, secondary measurements and tertiary measurements. Instruments and measuring systems, their classification –according to history of instruments, according to mode of measurement and according to the functional requirement and principles of operation. Their principles of operation. Functional elements of a generalized measurement system–basic functional elements –transducer element, signal conditioning element and data precision elements and auxiliary elements. Examples of instruments for identification of basic and auxiliary elements –bourdon tube pressure gauge with out and with electrical read out, spring balance and proving ring etc. Inaccuracy in measurement and it analysis –types of errors or limiting errors –propagation of error or uncertainty

Mechanical measurements and instrumentation Unit Two

Detector transducer elements

Detector transducer elements –introduction, classification and their principles –primary and secondarytransducers, mechanical transducer, pressure transducers and active, passive transducers, analogue transducers and digital transducers. Signal conditioning elements and their principles of operation, data presentation elements and types –visual display type, graphical recording type, magnetic type and digital type. Static performance characteristics of instruments: static sensitivity, independent and proportional linearity, hysteresis, threshold, resolutionand drift –zero and sensitivity drifts.
