Door closing force measuring device, especially for lift doors, comprises an assembly of lugs, force application lever elements and strain gauges that output force proportional signals

摘要

Door closing force measurement device (1) comprises a force sensor with at least a strain gauge element integrated within a housing (2) that has a number of lugs (3a-3c) that are rigidly connected to the housing. The lugs are positioned so that the strain gauge measures the force applied by at least one of the outer lugs (3a, 3b) to the inner lug via a load receiving arm (4a, 4b) to which a force (F 1, F 2) is applied by the closing action of the doors.
