Analog Position Transmitter FW22, FW31

Analog Position Transmitter FW22, FW31

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.

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.
