D.Marchiori s.r.l.
D.Marchiori (DMA) manufacture electromechanical devices to measure the relative rotation between movable surfaces which are used by the aircraft industry for aircraft control surface analysis.Angular position is measured by a goniometric scale and/or by an angular position sensor with 0.01 deg. resolution. Angular protractors can be supplied with two types of fixing plates: the screw-type plate and the suction-type plate. A special bearing on the mounting and a cylindrical hinge allows the protractor to check the relative rotation between movable surfaces having a transversal misalignment of 0.8 inch (20 mm) max.
