Non-intrusive actuators

Requirements for precise control included an extremely long actuator run time of over half an hour at 160rpm and 7000 revolutions per stroke. The demands were addressed by non-intrusive, encoder version actuator devices supplied by SIPOS Aktorik.

Sophisticated features that set the products apart include soft-start functionality and an automatic ‘retry if blocked’ response.

Other options explored by the operators, including alternative actuators and a potentiometer, could not meet the exacting demands of the scheme – the maximum revolutions achieved by alternative technology equated to just five thousand turns.
