Action of multiple resistance
As with electrics, a distinction is made in fluid technology between series and parallel resistances. For series circuits - as is the case for pipelines - the individual resistances are added ( series
Elbow fitting
Fitting , which forms an angle of normally 90° between the connection openings. It is offered as a pipe or screw-in fitting ( pipe screw connections ).
Angle measurement
Angles can be measured using analogue or digital methods. Analogue methods include rotating condensators, the capacity of which is a measure of the angle of rotation or a rotating potentiometer. Tacho
Angle encoder
Device for absolute angle measurements. A coded disc (graduated disc) turns in the beam path of an electro-optical reading device and creates signals there over a corresponding code track, which state
Repeat accuracy (reproducibility)
In general : Range within which the are spread if the same input signal is repeated ( Figure W 11 ). Measurement technology : Quantitative expression of a random error, which arises if different teste
Flow rate
Volume of fluid which flows through a cross-section in one time unit. In hydraulics the flow rate is generally stated in litres per minute (lpm). For example, filling a 10 litre water bucket at the ta
Flow rate amplification
States the percentage-based relationship between the electrical input signal and the hydraulic (here flow rate ) at zero load pressure in the range of the primarily linear characteristic (cf. transfer
