Number of samples taken per unit time. The parameter is stated in Hz.

Ratio of the amplitude at the output of a transfer element to the amplitude of the input signal , e.g. in a servo valve the ratio between the spool position and the electrical control signal.

Systems are divided according to the order (priority) of the linear differential equations that they represent in systems of the 1st, 2nd, ... nth order. In doing so, the coefficients of higher-order

Computer which controls the workflow of a machine or device. Its main task is: Controlling NC machines and accompanying hand-held devices, Monitoring safety measures, Supervising the production proces

The density of a fluid changes with temperature and pressure. It reduces with temperature and increases with pressure (Figure D 12) . The density-pressure function is determined by, among other things

Feedback-controlled adjustment : According to the specification above, only those adjustment processes in which the output variable is the control variable (b) are feedback-controlled. For hydraulic p

In the case of the accumulator supplies the size of the hydraulic accumulator is determined using the pressure oil requirements of all consumers dependent on the accumulator during a working cycle and

Regulation to calculate the value of one or more correcting variables from the value of one or more control deviations (DIN 66 201). The standard algorithm is described by the mathematical relationshi

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
