Often, the entire is labelled as the controller. In a more narrow sense, this is only understood as the computing element (device, program ) within the which continuously compares the control variable

Refers to the physical and mechanical process for recording a measured variable. Example: pressure measurement using a pressure gauge , , piezoresistive or analogue or digital measuring procedure or d

Interaction of one or more pumps (primary element) with one or more (secondary element, in most cases a hydraulic motor). The distance between the two devices is of no significance (open transmission)

Transfer factor

The expression is used for hydraulic components where the electronic control is integrated within the housing for the device. It mainly applies to proportional valves and servo valves (Figure I 15) .

The statement of a nominal size for valves is essentially only a reference value, which - contrary to the previously used "nominal width (NW)" - does not provide any indication of the cross-sections a

Measures used to prevent sound from being passed on from the (active) sounds generators (in hydraulic systems : pump, motor, valves ) to downstream components that are capable of oscillating (passive

General : Flow rate under nominal operating conditions. These are the conditions for which a device has been designed based on its application and when not subjected to a load (CETOP RP 100). For cont

Refers to the compliance of system elements ( compressibility of the oil, elasticity of the pipe, spring effect of a hydraulic accumulator ): The hydraulic capacity should be kept as low as possible i

Covers measures for the detection of faults (monitoring the occurrence of a fault), fault localisation (finding the cause of the fault) and fault indication (i.e. providing information on the cause of
