Abstract

Die Positioniereinrichtung für kolbenstangenlose Zylinder weist am Zylinderkörper (1) Markierungen auf, welche durch eine Sensoreinrichtung (15), die am Kraftabgabeschlitten (11) anzuordnen ist und mehrere, versetzte Sensoren umfaßt, abtastbar sind. Aus den Sensorsignalen ist mittels Interpolation die jeweilige Position des Kolbens (3) bzw. Kraftabgabeschlittens (11) sehr genau bestimmbar. The positioning device for rodless cylinders has on Cylinder body (1) markings, which by a Sensor device (15) to be arranged on the power delivery carriage (11) is and includes several, offset sensors, can be scanned. From the Sensor signals is the respective position of the by means of interpolation Piston (3) or power delivery carriage (11) can be determined very precisely.

Die Positioniereinrichtung ist bei einfachem Aufbau raumsparend anzuordnen. The positioning device saves space with a simple construction to arrange.
