Abstract
A device for measuring the angle of twist (20) is mounted to an electromotor (10). The housing (21) of the measuring device (20) is sealed from the housing (13) of the electromotor (10) by a sealing element (30). The sealing element is designed like a disk, is fixed by its outer circumference on the housing (21) and rests in a sealing manner by its inner circumference on the shaft (22) of the measuring device (20). The sealing element (30) can be at least partially deformed in a flexible manner so that it can yield to a pressure gradient between the motor housing (13) and the housing (21) of the measuring device.
