Automation and Calibration for Discrete Transducer: A Survey

This paper basically is on closed loop testing for discrete transducer. The close loop system determines the stable response of the testing parameters. The discrete transducer can measure all electrical quantities both AC and DC, such as current, voltage, power, frequency, resistance and so on. The transducer coverts the input signal into proportional DC signal that is independent of load an electrically isolated. AC power is measured using principle of TDM system. An analog DC signal is converted into a pulse output, for example to indicate the energy consumption. In this CALMET is the main part. It is basically used for calibration related as given input. Calibrator is used for adjusting, checking, and verification of electrical instrument characterized by high accuracy, high output power, light weight and small dimensions. CALMET is having another feature that standard interface RS232C enables connecting calibrator to computer and switched on to the automatic measurement systems.
