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
Fluid mechanics
Concerned with the physical characteristics and behaviour of fluids at rest (hydrostatics) and when moving (hydrokinetics)
Vertical column pressure gauge
Pressure gauge that operates based on the principle of the comparison of a pressure with the barometric pressure of a column of fluid (Figure F 23) . They are only suitable for measuring low pressures
Error tolerance
Statement of the insensitivity to errors/failures of computers that must operate “non-stop”. Error tolerance is achieved by means of a redundant system tailored to the computer in which the sub-system
Position measurement
when measuring the length of a path travelled. For path or position measurement, the location of a point is measured in relation to a fixed point of reference. In measurement technology position measu
