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
Planetary motor
Hydraulic motor from the group known as annular gear motors which operate in accordance with the planetary principle. The distinguishing feature of planetary motors is how lots of displacement chamber
Filter dirt load
Dirt holding capacity based on test dust
Real time computer
Computer that processes the incoming information immediately. Every computer in a must be a real time computer, otherwise it cannot intervene in the feedback control.
