Digital measuring procedure
Procedure in which the measured variable is assigned to an output variable that is a numeric representation of the measured variable quantised using pre-defined minimum step (according to DIN 1319). M
De-emulsifying mineral oils
Mineral oils that due to the careful selection of base oils and additives, and occasionally with the assistance of special admixtures, are able to rapidly separate out any water. This action is prefer
Bus system
System in which data and/or messages are exchanged sequentially (DIN 19 237). Within a computer the individual assemblies (processor, data and program memory and input-output units) are connected toge
Readily biodegradable fluids (hydraulic oils)
Biodegradable fluids are hydraulic fluids that biodegrade significantly more quickly than mineral oils. Biodegradation is a chemical conversion caused by microorganisms under aerobic conditions in an
Operating cycle frequency
The cycle frequency of a system foreseen for normal operation (DIN 19 237).
Steady state
The steady state of an element is the state to be maintained for a period as long as necessary that results from input signals that are constant over time, after all settling processes have ended (DIN
Axial gap compensation on gear pumps (so-called gap compensation)
Gear pumps have two sliding-contact areas (sealing areas): at the periphery as well as the two sides of the gear wheels, i.e. in the axial direction. The pressure-controlled leakage that occurs here c
Frequency response
Characterises the transient response of a linear system in the frequency range. It is independent on the type of system excitation, i.e. it is irrelevant whether a system is excited by a periodic or t
Two-line system
Accumulator drive system , which supplies its consumers via two pipeline networks, one with low-pressure and one with high-pressure, in order to save energy. In hydraulic systems, the low-pressure lin
Null range of a proportional spool valve
With proportional spool valves, the overlap/underlap at the individual control edges of the valve (overlap/underlap conditions) determine the flow rate signal characteristic curve ( Figure N 6 ) and t
