The damped natural oscillation of a system (e.g. spring-mass system or control circuit) is formed by oscillations or aperiodic movements that the system makes after external stimuli cease, i.e. when t

Change in the pressure in a device or a system as a function of pre-defined control signals. The pressure control can be undertaken by switching processes or continuously.

Connection together of digital modules with simple or complex functions ( integrated circuits ) to form complete controls.

Abbreviation for Application Specific Integrated Circuit. Integrated circuit that is manufactured specifically according to the requirements of the related user or for a specific task. Here it is poss

Change in the output signal over time for a rising function with a pre-defined rate of change on the input signal. To depict this situation the output signal xa can be plotted in relation to the rate

Range of values for the input signal from a measuring instrument (the measured variable ) which in accordance with the characteristic curve for this measuring instrument is unique and formed within sp

Filter to be installed in the pressure line within a circuit. The housing, therefore, must withstand the nominal pressure associated with the system, although this is not the case for the filter eleme

The volume V0 of a hydraulic medium increases (Vd) proportionally to the temperature difference with the expansion coefficient βT. For hydraulic oil, the expansion coefficient can be assumed to be 0.7

In general : For control elements with a piston design, this states the seal length between the allocated control edges ( Figure U 1 ). in rest position, together with the size of the gap, it determin

Proportionality factor between the pressure loss and dynamic pressure related to the circular cross section, when flowing through a straight of length 1 and diameter d. λ depends on the Reynolds numbe
