Null bias
With machine controls : The option to shift the origin for a coordinate axis in the control to a specified point. The position for the machine zero point remains stored in the control regardless of th
Piston seal
Seal at the piston for a cylinder . With single-acting cylinders ( plunger ), the piston is only subjected to pressure on one side so only needs sealing in one direction in most cases. For hydraulic c
Filtration
To remove particles of dirt that the pressure fluid is carrying with the aid of filtration of a wide range of types.
Equivalent circuit
Method for making the functional - and often complex - relationships involved in the operation of hydraulic devices visible by means of schematics (circuit diagrams) in which the various processes are
Fail safe position
Position which control elements take if parts of them become defective or fail. The fail safe position triggers either a backup operation or secures a position which ensures the safety of the system (
Self-monitoring of systems
Sub-field of diagnostic technology, in which an electronic system, e.g. a control or a measurement system regenerates a simulation using (generally present) microprocessors, which are used to monitor
Internal feedback control
that within a device or a closed system contain, e.g. a continuously adjustable valve or a linear amplifier , mostly a closed circuit position control system that improves the accuracy and reproducibi
Elastic materials
Most important material group for seals . Due to their elastic properties they can change shape on installation, adapt to deviations in the geometric shape of the surface to be sealed and make possibl
Amplitude response
The amplitude response is the magnitude |F (jω)|. The two lines represent in mathematics the magnitude of the frequency response as a function of the circular frequency. Graphically the magnitude of t
Auxiliary variables
All variables required in valves to convert the input signal into an . They are mainly used for the purpose of power gain (amplification) (DIN 24 311).
