Device for reducing the noise of a potentiometer position evaluation

In potentiometric transmitters, signal interruptions of the potentiometer current occasionally occur. These signal interruptions can be avoided if care is taken that the slider current (Is) picked up at the potentiometer output (S) remains less than one microampere. So that an appropriate evaluation...

Beschreibung
Zusammenfassung:	In potentiometric transmitters, signal interruptions of the potentiometer current occasionally occur. These signal interruptions can be avoided if care is taken that the slider current (Is) picked up at the potentiometer output (S) remains less than one microampere. So that an appropriate evaluation can occur in the control device, the slider current is amplified to about 40 microamperes in an interposed amplifier device. The amplifier device is usually arranged in the vicinity of the potentiometer, for example on an adapter plug which is plugged onto the potentiometer housing.
