Abstract

Die Erfindung betrifft eine Positionsmessvorrichtung (10) zum Ermitteln von Winkel- oder Längspositionen. Längen- oder Winkelmesseinrichtungen sind hinlänglichen bekannt. DOLLAR A Die Erfindung hat sich die Aufgabe gestellt, eine neuartige Positionsmessvorrichtung bereitzustellen, die auf der sogenannten Nonius-Interpolation beruht, um absolute Positionswerte zu ermitteln. DOLLAR A Die Positionsmessvorrichtung (10) weist hierzu eine Auswerteeinrichtung (120) und eine Maßverkörperung (30, 130) auf, die wenigstens drei Spuren (140, 150, 160) mit jeweils einer unterschiedlichen Anzahl von Teilungsmarkierungen enthalten. Jeder Spur ist eine Abtasteinrichtung (50, 55, 60, 65, 70, 75) zugeordnet. Die erste Spur (150) der Maßverkörperung (130) weist N Teilungsmarkierungen, die zweite Spur (160) N-1 Teilungsmarkierungen und die dritte Spur (140) N-K Teilungsmarkierungen auf, wobei K > 1 ist. Mit Hilfe der bei Abtastung der ersten (150) und dritten (140) Spur erzeugten Abtastsignale erfolgt eine Unterteilung der Maßverkörperung (30, 130) in K-identische Segmente.The invention relates to a position measuring device (10) for determining angular or longitudinal positions. Length or angle measuring devices are well known. DOLLAR A The object of the invention has been found to provide a novel position measuring device, which is based on the so-called vernier interpolation to determine absolute position values. DOLLAR A The position measuring device (10) has for this purpose an evaluation device (120) and a material measure (30, 130), which contain at least three tracks (140, 150, 160) each having a different number of graduation marks. Each track is associated with a scanner (50, 55, 60, 65, 70, 75). The first track (150) of the scale (130) has N pitch marks, the second track (160) has N-1 pitch marks, and the third track (140) has N-K pitch marks, where K> 1. With the aid of the scanning signals generated when the first (150) and third (140) tracks are scanned, the scale (30, 130) is subdivided into K-identical segments.
