Signal area in which the signal input , signal linking and signal processing are with electrical components. These are predominantly switches, relays and contactors. Electric signal processing has bec

Measuring procedure in which within the measuring range every value of the measured variable as an input variable is continuously assigned a value in the output range. The continuous assignment betwee

Indicates the extent to which force or pressure rises at the zero point as a function of valve control spool deflection for a continuously adjustable valve if the drive is retained ( Figure K 34 ).

Is used to stabilise closed circuit position control systems and together with velocity feedback has an optimal action in these circuits. On poorly damped drives (such as hydraulic drives) acceleratio

Some of the oil film stuck to the piston shaft at the outlet of a cylinder is scraped off when the piston is inserted (results in leakage even in the case of an intact seal), while the other part is f

Interaction of various seals at a sealing point (e.g. on a piston rod) to address the increased sensitivity to leakage with operating conditions that are becoming harder at the same time: a situation

Pressure transducer based on the piezoresistive effect whereby pressure causes an elastic semiconductor structure to change, which in turn changes the values for resistances connected as a Wheatstone

Collective term for all hydraulic feedback controls with electrical (electronic) signal processing. As the to the hydraulics - the servo valves and proportional valves - has already been in use for so

The input signal U E for a device (e.g. high response proportional valve) or a system (e.g. control circuit) generally covers a range of U E = 0->U Nominal (max. signal). For high response proportiona
