Professor D.V.S. Recent Trends in Sensor Technologies. • Ideally there should be a straight line relationship so that equivalent changes in input produce the same order of change in output no matter where within the sensor’s range these occur. Electroanalytical Sensors. Here, the output is usually an ‘electrical quantity’ and measurand is a ‘physical quantity, property or condition which is to be measured’. The characteristics of the sensors and transducers and the operating principles of transducer technologies have been discussed in considerable detail. It is useful to anyone studying measurement systems and instrumentation but it is provided mainly in support of the EC module D227 – Control System Engineering.
