An analogue-digital converter converts an analogue input signal (a DC voltage) into a digital output signal, i.e. into a proportional number. The quantisation error caused by the stepwise digitisation

Ability of a hydraulic fluid to cover the surface over which it is distributed to a greater or lesser degree. Hydraulic fluids with good wetting ability adhere better to the surface. As a consequence

Sum of losses arising in a fluid system. It is comprised of the pressure losses caused by mechanical and hydraulic friction and flow losses , leakage losses , throttle losses , which generally constit

Non-contact seals , which are characterised by a final distance between sealing surfaces, in which the working medium (against which it is to be sealed) is located. The geometry of the sealing gap (si

Factors influencing the structure and function of hydraulic systems that result, amongst other things, from the task formulation. This includes environmental conditions, such as the range of the worki

Discrete controllers which, when a certain control deviation is exceeded, change the suddenly at various stages (DIN 19 225). Example based on a two-point controller: temperature control via a device

Fire-resistant fluids based on a solution of polymers (polyglycols) in water at a ratio of around 60:40. HFC pressure fluids have a viscosity of 30 to 45 mm2/s at 50°C and may be used instead of miner

Throttle forms

Several electrical sensors react more or less sensitively to temperature changes, which move the zero point and possibly change the sensitivity. They must therefore be balanced out by suitable measure

Multiple pump whose units supply separate circuits with a pressure-limiting valve because their working cycles overlap. If a constant pump is involved, the installed power will be equal to the total f
