Adjustment time
Time at which the correcting variable runs through the correcting range at the maximum considered correcting speed (DIN 19 226).
Wheel motor
Hydraulic motor , which can be integrated directly into the wheels of a vehicle. This produces a direct transfer of the force without interposing a manual transition, cardan shaft and differential gea
Solubility of gas in a hydraulic fluid
Fluids have the characteristic of dissolving certain amounts of gases. In mineral oil this ability increases linearly with pressure up to approx. 300 bar. Dalton's law states: V G = dissolved gas volu
Single or separate drive for machines
Every machine or even every cylinder , provided its movements overlap with others, has a dedicated pump with a size based on the highest load speed v k required (Figure E 13) . This means that high sp
Flow velocity in pipelines and valves
As the flow losses are determined in pipelines using the square of the flow velocity, certain velocity values should not be exceeded. These are tiered according to the pressure in the system and the p
Linear control signal
Here, linearity refers to the relationship between the input measured variable (e.g. distance, pressure) and the electrical , which should remain as constant as possible. Where this is not the case, i
Force measuring
Performed with the help of force sensors designed in such a way that the force introduced acts on a strain gauge bridge (two active and two passive strain gauges) upon compression.
Pulse sensor
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.
