The overall costs for a plant consist of the procurement costs A, ( Figure K 33 ) and operating costs K, which can fluctuate considerably in the field of hydraulics. They will depend primarily on over

Semiconductor component combining thousands of electronic functions within an area of a few mm2. It is mass-produced in the form of chips and is an essential feature of modern microelectronics.

Pulse width modulation

Characterisation of the nature and scope of the intervention in a control system by the operator and by feedback from the system to be controlled. Here in accordance with DIN 19 237 a differentiation

Memories made out of semiconductor elements which are generally integrated into computers as the main memory and used to prepare large volumes of data and programs. A distinction is made between: ROM:

Test method for determining the filtration efficiency in general ( retention rate, filtering grade ). This involves passing a specific mineral oil contaminated with quartz sand ( Air Cleaner Fine Test

Reaction force generated if a fluid flow changes direction and/or velocity. The force F acts on the fluid from the outside as a supporting force. The force exercised by the flow on the environment is

Takes into account along with the compressibility of the pressure fluid also the elasticity of the surrounding components as well as the connection line between the valve and . The equivalent bulk mod

without auxiliary energy, which converts an input signal into an with the same physical properties and a value range suitable for the downstream elements. Example: Voltage converter, electrical potent

Reversal of a pulse valve by purging (depressurising) the piloting line. Not used very often now, because switching may also occur in the event of an unintentional pressure drop.
