Hakuteksti "*".

Refers to a configuration whereby the output variable (e.g. velocity) is dependent on the load. Example: electric motor in series connection, power-controlled pump, compressed air cylinder (connection

Creation of feedback control and general control systems from ready-made program modules.

Derived from the natural frequency f o as follows: ω o = 2 π · f o

Pressure that is present at a specific point at a specific time (DIN 24 312).

The distance to be measured is divided into equal elements (increments), which are then counted. The distance covered is obtained from the total for the increments from a single point of reference. Th

Noise which contains short-lived and fast-rising changes in the of at least 5 to 10 dB (e.g. hammer blows, typewriters). Impulse noise is either measured using an impulse noise pressure meter or measu

Resistance which a fluid flowing inside pipes or similar bodies must overcome. It is higher for laminar flow than for turbulent flow: where A S = flow cross section.

Term used for hydraulic oils with anti-ageing and corrosion-protection properties for systems subjected to a high thermal load. Viscosity index 95 to 105. (requirement standard DIN 51 524, Part 1).

Damage to the hydraulic fluid primarily due to oxidisation (formation of acid residues) and polymerisation (enlargement of the hydrocarbon chains); creates sludge or resin-like coatings on device part

To assess the noise emissions, as a rule, the entire frequency range is not measured. Instead, specific frequency bands of practical significance are measured. This action is undertaken using electric
