values for the individual variables that occur in a specific operating state of a system. The variables may change during operation (CETOP RP 100). As rule the operating conditions include the stipulated performance

preferred in most cases because of the significantly shorter switching time. Proportional solenoids may be controlled in respect of force, distance or position. As far as force control is concerned, the [...] signal . The solenoid can also be used, however, in a closed circuit position control system , which may significantly improve the response sensitivity and reversal error too ( Figure P 20 ). Other aspects

Device for measuring pressure levels in fluid media. They may function directly (e.g. vertical column pressure gauge ) or indirectly, whereby elastic deflections, for example, are used to record the pressure

A system is able to handle oscillations –– i.e. oscillations may occur –– if a periodic exchange of energy takes place between two energy stores (spring-mass system, e.g. a hydrostatic transmission, in

output variable to a defined factor of what is normally a very weak input signal. The signal processing may be mechanical (e.g. copying) or electrical (electronic). This field is more accurately named elect
