Measuring device

Abstract

The invention relates to a measuring device (10) for recording at least one force and/or torque curve resulting when a control valve (32) is actuated by an actuating drive (34), comprising a housing (11) which can be arranged between the control valve (32) and the actuating drive (34). The housing (11) is provided with a first and a second connecting wall (14, 16) and at least one connecting element (18) which connects the first and the second connecting wall (14, 16). The first connecting wall (14) is connected to the actuating drive (34), and the second connecting wall (16) is connected to the control valve (32). A connecting shaft (12) for connecting a drive shaft of the actuating drive (34) to an actuating shaft of a control valve (32) is arranged in a central through-opening (14c, 16c) in the two connecting walls (14, 16). The connecting shaft (12) penetrates the measuring device (10). The connecting shaft (12) is arranged at a distance from and freely rotatable with respect to the connecting walls (14, 16), and at least one resilient element is provided between the first connecting wall (14) and the connecting element (18), with a measuring unit being provided in the housing (11). The measuring unit has at least two sub-measuring units. The first sub-measuring unit is in the form of a torque sensor unit, and the second sub-measuring unit is in the form of a rotational-angle sensor unit. The sub-measuring units each have a signal transmitter and a signal receiver. The signal receivers are arranged in a common measuring module (20). The invention is characterized in that the first signal transmitter is arranged on the first connecting wall (14), and the second signal transmitter is arranged on the connecting shaft (12).
