Covers all the various measuring instruments and auxiliary instruments required to pick up a measured variable , relay and modify a measured signal and output a measured value to represent a measured

Of a hydraulic motor displacement Of a hydraulic pump output volume or flow rate Of a cylinder Geometric volume based on piston area and piston stroke. With differential pistons, the volume at the rea

Controller with a delay element (e.g. PT1).

The oil volume Vp of the piston side of hydraulic cylinders is calculated from the diameter of the piston dp, der Hublänge s und der Anzahl der cylinder ic. Calculate the piston side volume directly a

Overload protection helps secure the system against excessive operating pressures. In fluid technology, the overload protection is provided by the working method of the pressure-limiting valve, which

Device which divides the delivery flow of a hydraulic pump into two or more equal or unequal sub-flows. It consists of a suitable number of displacement units based on gears or pistons, whose shafts a

Auxiliary device for measuring pressure and/or temperature at devices and when installed (in operation). This is only possible if some thought has already been paid during the planning stage for a sys

Transient response of a hydraulic motor during the run up to working speed. In this context, the run up time constant is of most interest, as is any overshoot.

Safety circuit for the elimination of a faulty device or part of a control system with redundant circuits. The signal is generally triggered by measures for fault detection .

Periodic pressure surge in a hydraulic fluid that is caused by the constant changing of the individual displacement units in a hydraulic pump from the suction phase to the pressure phase and vice-vers
