Overview

CONVERTS POSITION, GATE, WIDTH, WEIGHT etc. into ELECTRICAL SIGNALS.
Wire Position Sensor

The Analog Position Transmitter incorporates a precision potentiometer and converts the linear motion of an object to be measured into electric resistance proportional to its position.

Structural diagram

A stainless steel wire is wound around a wire drum which incorporates a spring. The shaft of the drum is connected to the shaft of the potentiometer.
