Measuring instrument which outputs the measured value for the variable measured ( measured variable ). It either serves as a visible output or an indirect output. Many signal output elements still fea

Illustration of a system with symbols (previously: switching symbols) to illustrate the order of the individual devices and their functional workflow. The circuit diagram must therefore allow the iden

Switching element for mechanical actuation whereby the gradient of the increase gives the transition time and associated acceleration, while the cam length determines how long the actuation effect las

Arrangement whereby a mechanical pressure is largely compensated for by an opposing hydraulic pressure. The hydraulic pressure is generally removed from the system in such cases. Example: hydrostatica

Bandwidth each side of the ideal characteristic curve in a measuring device that contains a systematic error as well as the random errors, provided it can be estimated (Figure F 6) . The description o

The volumetric efficiency describes the ratio of the effective (actually absorbed or issued) flow rate to the theoretical flow rate based on the displacement kinematics and the rotation speed. For pum

Valve assembly system in which either all valves for a machine control or only individual, recurring function groups (function blocks) are arranged on a block. In both cases the block has the task of

To monitor the state of a hydraulic fluid there are three variations, each with a different information value: Visual inspection : The colour of a pressure fluid (in particular mineral oil) is a measu

Torque curve of hydraulic motors: The torque curve on fixed displacement motors is only dependent on the usable pressure (pressure difference) (Figure D 38 a) , on variable displacement motors on the

Combination of two filters with a control unit so that the entire flow rate can be passed through one of the two filters while the other can be cleaned. (Figure D 32)
