Shaft torsion and=or relative angular motion measuring device - has two coil systems with annular coils and ring segments forming air gap

摘要

The torsion measuring arrangement contains two coil systems (5,6) mounted on the shaft configuration (3,4) so as to leave an air gap (13) between the ring segments. One of the ring segments of the first coil system is connected to an annular coil and at least one of the ring segments of the second coil system is connected to a second annular coil. The first (2) and second (7,8) annular coils are enclosed by opposing ring coils (1;9,10), which hold a coil ring arrangement, so as to leave an air gap (14). ADVANTAGE - Accurate, high reproducibility.
