GEFRAN linear potentiometers and accessories are now available from AutomationDirect. Linear potentiometers are used to detect position and linear direction movement. A sliding contact moves along a linear resistive element acting as a variable resistor.
The proportional change in resistance indicates the position and provides a distance measurement signal. A signal conditioner can be used with the potentiometers to convert the signal to 0-10V or 4-20mA.
