Description

technical field

[0001] The invention relates to a sensor device for a hydraulic ram unit. Background technique

[0002] Hydraulic piston units have different operating states which can be characterized by process and state variables such as temperature, pressure, rotational speed of the drive shaft or the pressure medium volume flow of the piston unit. In order to obtain these variables, the plunger unit has a plurality of sensors, referred to as sensor devices.

[0003] Laid-open document DE 10 2005 059 564 A1 shows a hydraulic plunger unit with a large number of discrete sensors which are arranged distributed on the plunger unit. In order to connect the individual sensors, an expensive cable harness is provided here, one cable harness being required for each sensor.

[0004] The disadvantage of this solution is that the distributed sensors are susceptible to mechanical damage. Furthermore, the connection to the control unit via the cable harness is complex and, in the v...
