Null drift
Changeable deviations around the zero point for a measuring instrument or a machine as a result of external influences (e.g. temperature). It can be rectified by means of a null-adjustment signal.
Mechanical damping
Damping or buffering via friction or spring-based components.
Idling pressure
Pressure generated when a device or system is idling (DIN 24 312).
Capacitive position measurement
Process whereby a distance variable is converted into a change in capacitance for a capacitor. Advantage: extremely high sensitivity and suitable for very fast movements. Disadvantage: only suitable f
Force: impulse, signal: pulse
1. Product of the weight m and velocity v for a mass point: The impulse/pulse is vectorial variable; its direction is same as the velocity involved. The time differential quotient for the impulse/puls
IEC
International grouping of specialist associations (e.g. VDE) for the purpose of standardising terminology, components and regulations within the field of electrical engineering.
Hydraulic damping (of servomotors)
Damping D h of a hydraulic system which also applies in the absence of any leakage or friction: where A = piston area, σ = hydr. conductance of the system, m = total weight moved, V = oil volume under
Cooling capacity flow
The heat output to be dissipated Pc of a flow rate Q is calculated from the temperature difference at inlet and outlet, the specific heat capacity of the medium c (~1.88 kJ/(kg*K) for Oil, ~4.18 kJ/(k
Flow divider
Valve , which divides the incoming volumetric flow into two previously determined subflows according to the throttle principle. As the control piston of the valve works like a , the same also applies
