Setting point
Temperature, at which a liquid can no longer flow under the effect of its own mass when cooled down under defined conditions. In the course of adapting to international standards, the setting point was
Error tolerance range
curve in a measuring device that contains a systematic error as well as the random errors, provided it can be estimated (Figure F 6) . The description of the accuracy limits by means of an error tolerance range
Load pressure compensation
flow control valve ). Continuously adjustable valves are combined for this purpose with a , which can be arranged at the inlet or the outlet ( Figure L 8 ).
Correction of characteristics
order to compensate for non-linearities , reduce hysteresis and the like. This kind of correction can involve additions, multiplications or substitution (Figure K 9) . It takes place during signal processing
Elastic materials
Most important material group for seals . Due to their elastic properties they can change shape on installation, adapt to deviations in the geometric shape of the surface to be sealed and make possible
Linear control signal
it may prove helpful to store the target characteristic curve in a memory so the measured signal can be corrected on an ongoing basis.
Rotary pipe joint
to a moving (oscillating) part of a machine. Along with oscillating movements, rotary pipe joints can in general also undertake relatively slow rotary movements.
Binary data processors
Systems in which only binary signals are transferred. They can contain, along with discontinuous two-point elements, also continuous elements provided the binary character of the overall system is retained
Speed control circuit
of a hydraulic motor) as a controlled variable as accurately as possible to a setpoint. This action can be undertaken by changing the flow Q 2, i.e. the pump delivery flow (Figure D 41) , or the displacement
Volume reduction on pressure increase
pressure Δp is increased. The factor is the reciprocal of the Kompressionsmodul K. The value of K can be assumed to be 1400 MPa for a hydraulic fluid.
