Spring arms and measuring wheels (photo) have been added to this company’s encoder portfolio, thus offering a reliable solution for measuring linear moving objects. The freely combinable spring arms and measuring wheel systems enable the measurement of lengths and speeds with conventional encoders. This makes it possible to monitor the progress or speed of conveyor belts easily. The three spring arms cover different requirement profiles, from price-sensitive/space-saving to low-maintenance/flexible spring arms, to particularly robust spring arms providing high-contact pressure. All spring-arm variants were developed for incremental and absolute solid shaft encoders. The spring arms are combined with measuring wheels with circumferences from 200 to 500 mm. — Hans Turck GmbH & Co. KG, Mülheim an der Ruhr, Germany
