Operating defect
Defect caused by the operation of the system, such as the loosening of components, failure of safety devices, maintenance defects, consequential damage as a result of wear, corrosion, ageing etc. as w
Baud
Measure for the transmission speed for data: 1 baud = 1 bit/s. Named after the French engineer Jean Marie Baudot (1845—1903). data rate .
Port
End of a flow path in a device to which pipes for the transport of the hydraulic fluid to or from the device can be connected. As the type of port has a major effect on how the installation is assembl
Requirement profile
Sum of all requirements that are placed on a machine (installation) in chronological order and by location. The requirement profile defines the type and magnitude of the load on the devices used in th
Electro-mechanical signal converters
Devices that convert electrical input signals into mechanical movements (or forces/torques) that in turn actuate hydraulic control elements . They therefore form the actual between the electrical sign
Point control
Allows moving to a certain point on the level, without needing to define a functional relationship along the movement path in the individual path axes. The movements may be performed simultaneously or
PSI
English unit of pressure. Conversion: 1 bar = 14.5 psi and 1 psi = 0.07 bar (i.e. 1 000 psi = 70 bar).
Paper filter
Filter whose filter element contains paper made of natural or artificial fibres. Depending on the form involved, a distinction is made between star-shaped paper filters and wound paper filters.
Anharmonic oscillation
All oscillations which are not harmonic, i.e. which are not periodic sine oscillations with a given frequency. A typical form of anharmonic oscillation is noise .
Minimum pressure
Lower limit for a pressure value at which a device or system will still be functional (DIN 24 311).
