Quotient of an observed change in the and the causing (sufficiently small) change in the input signal (or the measured variable ). The term sensitivity of a measuring device is primarily used for indi

Velocity at which the pressure in a device increases. It is measured in bar/s and defines, e.g. on pumps, the amplitude of the pressure pulsation-induced oscillations and with it also the amount of no

Switching system which makes it possible to operate a differential cylinder in a network with impressed pressure ( constant pressure network ) without experiencing pressure losses due to throttles, an

Also termed open transmission. hydrostatic transmission on which the pump and motor operate separated from each other. Pipes and hose lines make the hydraulic connection (Figure F 10) . Opposite: inte

The pressure gain on a continuously adjustable valve corresponds to the gradient on the pressure-signal function , e.g. 2,000 bar/mA. It is crucial for the accuracy that can be achieved with a control

Installation of one or more valves in one plate, which is placed between two valves or between a valve and base plate (block) (Figure Z 19). Pressure valves , check valves and flow valves are suitable

Valve assembly method in which individual function blocks of a machine control are connected together to form vertical stacking assemblies above each other or to form series connections (beside each o

In the case of : signal converter with auxiliary energy used to amplify the power (DIN 19 226).

Sudden noise created when a flow rate is suddenly stopped as a valve closes or when the compression volume, e.g. of a cylinder meets the oil column in the feedback line at a high speed due to the sudd
