Angle measuring instrument for determining angle between two mobile elements has stretch sensors extending over entire length of flexible strip on each flat side of flexible strip to measure flexible strip longitudinal direction

摘要

A flexible strip (20) has two longitudinal ends (26,28) connectable to mobile elements (12,14). Stretch sensors (35,36) for measuring the flexible strip longitudinal direction extend over the entire length of the flexible strip on each flexible strip flat side (201,202). The flexible strip exhibits a constant thickness along the length.
