Cross-section dependent pressure loss
Pressure losses produced by flow deflections and velocity changes. The pressure loss factor ξ is required for the calculation. The pressure losses increase with the square of the flow velocity.
Pressure ratings
DIN 24 312 and DIN 2401 contain a summary of the pressure ratings used in the area of fluid technology as well as the preferred pressure values in this area. The ratings should be used, as far as poss
Digital

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
