Measuring system in which the information on the actual (absolute) position is always available. For this purpose the sensor (e.g. glass measuring scale) must provide additional information. This info

Feature that on some adjusting features on pumps, e.g. power controllers, reduces or limits the pump delivery flow on reaching an upper adjustable pressure to prevent the pressure-limiting valve trigg

In general : Valve with three controlled ports. For directional valves : Valve with inlet, cylinder line, outlet (suitable to control a single action cylinder).

Ratio of the output power to the input power of a system or device ( total efficiency in the case of hydraulic devices).

Devices, which control a power flow. In fluid technology these are the valves, which influence the flow rate in terms of direction ( directional valves ), size ( flow valves ) and pressure ( pressure

In general : Determination of a physical variable of a process and further use at another point. This is generally a feedback control, but may also be data collection, for example. In control technolo

Sum of all the pressure losses that occur at the various throttling points in a system (i.e. wherever there is a cross-section constriction). Another type of throttle loss occurs if in a system with c

Low-pressure accumulator (3 to 6 bar) to create a traverse speed in the case of large cylinders, for which there is no more pump for rapid traverse . The pre-charge container is refilled with the refl

Control , in which the signal action is synchronised with a clock signal (DIN 19 237). The clock signal comes from a clock device (clock, clock amplifier). This means that changes to the input signals

A newer group of materials between elastomers and thermoplastics : They have the properties of an elastomer up to approximately 70° C (high strength, good elasticity), but react like thermoplastics at
