If a flow is created between two stationary areas due to a pressure difference, (theoretically) a symmetrical velocity profile will form ( Figure S 101 a ), which is caused by adhesion of the fluid to

Hydraulic pump with a to the pressure, the flow rate or the state variable of an actuator . Servo pump Also known as variable displacement pump. The reason for using a variable pump is to improve the

Controllers where the relationship between input variables (system variables) and output variables ( correcting variables ) is a linear one. Linear regulators also include both single loop controllers

Annular gear pump/motor

A control that operates within the signal processing with digital signals and that primarily processes numerically represented signals (Figure D 28) . The signal processing is undertaken primarily wit

Sensor that changes its electrical resistance in proportion to the mechanical strain under load. Strain gauges are suitable for the electrical measurement of all mechanical variables that can produce

Systems designed to automatically perform monitoring tasks in the area of signal distribution . They are intended to analyse the signal paths to be monitored and compare them to the stored target path

Piston cylinder : The mechanical force F K is created by the influence of the pressure p of the transfer medium on the piston area A K (the most common form of a cylinder): With this approach, forces

Process to minimise the influence of interference in The correcting variable is subjected to a disturbance variable which compensates for interference present in the controlled subsystem by estimating

Working positions of a valve that are used in the case of a switching process and have a binary character, i.e. they are only "open" or "closed" based on their actuation (" black-white valves ").
