Measured variable for the pressure difference between p 1 and p 2 . The differential pressure can be positive or negative, depending on whether p 1 is greater than p 2 or smaller than p 2 (Figure D 23)

"bar" is frequently used in modern fluid technology, as that way the traditional numerical values can still be used for pressures. In SI units the unit "pascal" is recommended for pressures: 1Pa = 1 N/m2

variables, with one or more variable parameters being used as parameters. This kind of performance map can provide a complete overview of the behaviour of the respective device in all operating states recorded

full pump delivery flow from the constant pump passes through all the valves . Very high flow losses can occur with open centre systems. Opposite: closed centre system .

Hydraulic motor with a larger number of displacement units , which are pooled into two or three groups and can be switched in order to achieve different displacement and therefore different speeds. The system of

amplifier. Measuring amplifiers with carrier frequency are required for inductive transducers and can also be used in resistive systems.

regarded as a special case of the transfer behaviour , in which the input variables remain constant. It can be described by characteristic equations or curves.

Cylinder design that is equipped with several, mostly binary tiered pistons that can be operated in any combination. Therefore with n pistons 2n-1 positions are obtained with a positioning accuracy that

digital systems a gearwheel generates pulses in a coil and these pulses are counted (Figure D 40) . They can operate as accurately as necessary via the number of teeth and are very economical.

lasts. Cams are attached to moving supports (e.g. discs) or to fixed cam rails in such a way that they can be moved. They support precise switching, although they are not very flexible for adjustment purposes
