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
Analogue measured values
The majority of measuring systems are analogue. In theory they have an infinitely high accuracy that is practice is however limited by the reading accuracy (resolution) and costs. Analogue measured va
Acoustic impedance
Quotient of the complex amplitudes of acoustic pressure and acoustic flow (acc. DIN 1320). The acoustic impedance describes the acoustic behaviour of a component. For hydraulics this quotient comprise
Adaptation
Adaptation (tracking) e.g. of the gain to changes in parameters in the controlled subsystem.
Absolute pressure
Pressure in an installation in relation to zero pressure in a completely empty space (100 % vacuum) (according to DIN 1314) (Figure A 5) .
Foreword to the online edition of the O+P-Fachlexikon "Fluidtechnik von A bis Z" (O+P technical glossary "Fluid technology from A to Z")
Hydraulic and pneumatic drive and control technology – collectively termed fluid technology – is a comparatively young specialist area of drive and automation technology that only started to become us
Lowering brake valve
Back pressure valve with the task of preventing pulling loads on cylinders or motors from causing uncontrolled lowering. For this purpose, it is pre-loaded to a higher pressure than the pressure corre
Filling pressure
Pressure that is produced after filling, e.g. on the gas side of a hydraulic accumulator or on pumps on which the suction side is pressurised.
