Introduction to Mechanical Measurement – significance of
mechanical measurement; Fundamental methods of measurement; Classification of
Stages in generalized measuring system – Sensor-Transducer
stage, Signal-Conditioning stage, Readout-Recording stage; Types of input
quantities; Active and Passive transducers.
Performance characteristic of measuring devices –
Static characteristics – Accuracy, Precision, Repeatability,
Sensitivity, Reproducibility, Drift, Resolution, Threshold, Hysteresis, Static
Dynamic characteristics- different order systems and their
response-, Measuring lag, Fidelity, Dynamic error; Types of errors in
Transducers – Working, Classification of transducers.
Motion and Dimension measurement – LVDT – Principle,
applications, advantages and limitations.
