Stability of a hydraulic fluid
Resistance of a liquid to permanent changes of its properties in normal storage and load conditions (CETOP RP 100).
Signal state
Any possible value of a digital signal. Example: The binary values O or L are allocated to certain voltage ranges or switching states (EDIN 19 226 T 5).
Pipe inductance
Pipe inductance is a measure of the pressure difference required, assuming the flow is free of friction, to change the flow rate inside a pipe. It is based on the mass inertia associated with the flui
Torque measurement
The most common methods use measuring shafts and . They can measure precisely, however, the measured variable must be tapped via sliding contacts or wirelessly. Conversely, with hydraulic torque measu
Cascaded control
Term for a specific type of control whereby functions are performed one after the other. The technique in question, which involves optimising how a device is used, has now been overtaken by synchronou
Internal power split
As far as hydrostatic transmissions with an internal power split are concerned, the input torque from the drive motor is fed through the transmission using mechanical means only, while hydraulic torqu
Indirect measuring methods
The measured value sought is established by converting the measured variable sought into another measurable physical variable which provides an unambiguous description of the measured variable based o
Impeller
Hydraulic pump which operates in accordance with the hydrodynamic principle (centrifugal pump) and is used as a filling pump for hydrostatic pumps, particularly variable pumps (Figure I 3) . Advantage
