Natural angular frequency ω e
Given by the natural frequency as
Filter for oil removal
Filter whose task is to filter out oil droplets from compressed air. They are installed in the compressor group behind the recooler and contain a specific filter element ( Figure O 3 ).
Holding current
Minimum current needed to flow in an electrical load circuit (e.g. in a solenoid or another electro-mechanical signal converter) in order for a valve to be held in the closed position by the electro-m
Inductive position measurement
Inductive sensors are the favoured choice for short lengths in fluids-based drive technology. These are passive sensors based on the principle of self-induction. If an alternating current flows throug
Destroke time of a pump
Time that a variable pump requires to adjust from the max. flow rate Q max to a flow rate of zero. In general this time is shorter than the on-stroke time .
Pressure loss
Lasting pressure reduction as a consequence of energy conversion (e.g. at a flow resistance ) (DIN 24 312). The pressure loss along with the leakage loss is the most important source of loss in hydrau
Relative signal amplitude
Ratio of the magnitude of the signal considered to the magnitude of the nominal signal (max. signal). For the stability of a closed loop control system (e.g. closed loop position control system ) the
Logic element
Electrical, electronic, pneumatic, mechanical or hydraulic component capable of performing a logic function ( Figure L 26 ).
Laplace transformation
Laplace transformation is a method for solving linear differential equations with constant coefficients based on given initial conditions. It can also be used for fault functions which give the value
Linear control theory
This assumes there are linear relationships within the . As well as the controller (linear controller), the model ( model of open loop system ) for the controlled subsystem must also behave in a linea
