Position transducers employing conductive plastic resistance and collector tracks provide direct means of measurement in control and regulation systems and in instrumentation.
Using this type of transducer, problems traditionally associated with rotary potentiometers, especially reliability, life expetancy, accuracy and operational speed, are overcome. Thus opening up new fields of application in direct position measurement.
A ball coupling (which may be fitted to either end of the shaft) offers backlash-free operation even where there are parallel or angular errors between the transducer axis and the direction of movement. The elastomer-damped, independently sprung precious-metal multi-fingered wiper has been designed to provide a reliable contact even at high speeds or when experiencing shock or vibration.
