Measuring transducer MI454 is designed to convert the wiper position of potentiometer or slide wire into an accurate proportional DC current or DC voltage signal.Typically these kinds of transducers are used for measuring of resistance on TAP position changers, used on high voltage transformers or to measure variable resistance on 3 wire system. The analogue output signal is proportional to the measured value and it is appropriate for regulation of analogue and digital devices.
