Servo actuators
Term used for operating elements (cylinders, motors, swivel motors ), which are controlled by a continuously adjustable valve . We sometimes use this term in place of servo cylinder .
Flow rate saturation range
Range of the flow rate/signal characteristic curve, in which the flow rate does not significantly change despite an increasing input signal (EDIN 24 311).
Churning losses
Losses arising in hydraulic pumps and motors when the housing is full of oil and the components are moving around inside. These are dependent on the rotation speed and — particularly during idling — m
Correction of characteristics
Changing the stationary characteristic curve for a device by modifying the input signal in order to compensate for non-linearities , reduce hysteresis and the like. This kind of correction can involve
Contact ratio t p
Contacting part of a surface detailed profile, i.e. the area between depressions as a percentage of the overall surface area ( Figure T 15 ). To keep the wear of the seals within a limit the surface a
Temperature response
Defined systematic relationship between a physical variable and the temperature such that the physical variable is changed by changing the temperature. Example: Thermal expansion, change of the specif
Electronic filter
Electronic circuit that separates the useful portion of a signal (e.g. measured signal) from the superimposed interference. They are either part of other measuring instruments (e.g. measuring amplifie
