Signal generator, e.g. limit switches, limit pick ups, directional valves and the like, used to produce a pulse-like signal for a control process.

Arrangement whereby a mechanical pressure is compensated for by an opposing hydraulic pressure created by a separate power pack (Figure H 27) . The hydrostatic bearing is generally used when the inten

Control whereby the respective cycle runs automatically, but the following cycle is initiated manually.

Position sensor

Incremental displacement transducer that comprises a glass scale in which a series of graduations are cut; these graduations are scanned optically ( incremental position measurement ).

Sum of the static and dynamic pressure elements in a location (DIN 24 312).

Time that is required for a sudden change in the operation pressure with a pre-defined deviation to settle.

Pressure at the inlet to a device or a system (DIN 24 312). Self-priming pumps generate a negative pressure during priming if the fluid feed height is not positive. Min. and max. inlet pressure are de

Damping that a system provides due to its nature (that can only be increased by means of specific measures).

Characterises the relationship between the pressure and the flow in a device through which a compressible medium is flowing.
