Theoretical preliminary work for the construction of a controller. An analysis is performed of the dynamic of the system. Then a search is conducted to find a controller that can provide this data and

Standard pressure gauge with a spring-based elastic measuring element which features a spring contact in addition to the pointer with its electrical limit value indicators to ensure there is an upper

In principle the rotation speed of a hydraulic motor is defined by the ratio of the flow rate supplied Q 1 to the displacement of the motor V 2: The highest rotation speed is reached on fixed displace

Collective term for the characteristics that influence the operation of devices and systems up to installations. These include efficiency characteristics , flow diagram , pressure-signal functions as

Obsolete term for inlet pressure . According to DIN 24 312

A physical variable is analogous to another physical variable or mathematical variable if it changes with a specific relationship to the first variable. The relationship between these two variables ca

Pressure that is present at a specific point in a system at a specific time. It represents an instantaneous point on the pressure-time curve during operation. The operating pressure corresponds to the

Element that measures the instantaneous values of a continuous input variable u(t) at specific times and saves and holds the value measured until the next sampling. The output function v(t) then has t

The gear pump is a machine for conveying fluids in accordance with the Positive displacement principle . In principle it consists of three components: a housing with inlet and outlet and two gear whee

In the case of a control, the signal is transferred only in one direction. There is always one open action flow or one open impact chain ( Figure S 87 a ). A control chain as a whole can always be con
