Compact, redundant potentiometers

August 2012 Electrical Power & Protection

Potentiometric transmitters from FSG’s PK 609 series are based on a high resolution resistor element made from conductive plastic, printed on fibreglass-reinforced support material. Designed as triple ganged potentiometers, they have a maximum active angle of 350°. The intrinsically safe units are suitable for use in applications with explosive atmospheres. For adjustment of the measuring range, the potentiometers can be equipped with short-circuiting tracks, taps and function windings, for example according to a sine or cosine function over 360°. With a housing diameter of merely 22 mm and a weight of 15 g, they can be integrated easily into machines and plants, even if installation space is limited. Suitable for use at maximum temperatures of 120°C, potentiometers from the PK 609 series reach a lifetime of 50 million wiper movements. The cost-efficient, low-maintenance units are highly precise and can be adapted for individual applications in many fields. They therefore still provide an attractive alternative to wear-free but more costly digital components.
