Refers to a character set that comprises as a minimum the decimal numbers and letters. It is useful to define the scope of the alphanumeric character set in the specific case (EDIN 44 300 part 2).

Chemical additive that changes the existing characteristics of a fluid or adds new characteristics (CETOP RP 100). The natural substance mineral oil is lacking a series of characteristics for its task

Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in then form of a seated or ball valve. One of the most important sources of contamination in hydraul

Flow through a valve as determined by a given load and a specific signal. With continuously adjustable valves , the load flow is described in terms of the flow rate load function Q L=f(y,pL).

Measures for the automatic adjustment of the controller parameters . The majority of operations that are necessary for the re-optimisation of can be defined in schemas and described by formula-based r

The elements in hydrostatic displacement machines , which bring about the suction and transport process. They include, for example, the teeth in geared machines, the vanes in vane machines or the pist

Sum of all manipulations required to trigger certain functions in the process (in the system) using defined input signals (DIN 19 237). A distinction is made between analogue , digital and binary sign

Design category for seals with a pronounced lip. The main examples are grooved ring seals with one or two lips ( Figure L 23 ), as well as roof-shaped seals and lip seals — although the latter are not

which relies on the piezoresistive effect of semiconductors under a mechanical load. Here, as well as depending on the strain, the measured value is also highly dependent on the temperature. The measu
