Analog Position Transmitter  FW80

Overview

Wire Position Sensor

The FW80 analog position transmitter has two versions: a long-stroke type and an ultra-precision type. The 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 construction drawing of this device can be found in Fig. 8. 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 via the synchro-belt pulley.
