Intended signal setting of storage elements in a control device as a prerequisite for the implementation of the program. In the signal range an intended signal state as the prerequisite for the realis

The heat output to be dissipated Pc of a flow rate Q is calculated from the temperature difference at inlet and outlet, the specific heat capacity of the medium c (~1.88 kJ/(kg*K) for Oil, ~4.18 kJ/(k

Valve , which divides the incoming volumetric flow into two previously determined subflows according to the throttle principle. As the control piston of the valve works like a , the same also applies

Shock in the pressure fluid due to the release of kinetic energy if the flow rate suddenly stops (e.g. due to closing a valve or a piston moving against a stop). The pressure wave produced in this man

Measure for the usage of a device (e.g. a pump) during a working cycle. The basis for determining this parameter is the sequence diagram for the installation. The utilisation factor plays a role in th

(Discrete) controller , in which the controller output signal is discontinuous despite a continuous input signal (switching controller) Examples: 2-point or 3-point controller (DIN 19 225).

For use in this is a group of continuously adjustable valves, in which a constant input signal brings about a proportional. A distinction is made between mechanical-hydraulic servo valves ( copying va

Controller concepts

Even an intact elastic seal will not always be tight. The reason for this is a complicated interplay involving drag flow , the direction of movement for the areas to be sealed, the shape and hardness

Highest frequency of a periodic signal at which the signal is still just processed without errors. Frequency limit of a signal component : Inverse of the sum of the minimum pulse duration and the mini
