Tachogenerator
Device used to measure angular rotation speed. Tachogenerators can work as DC or AC generators. DC generator : The most commonly used process, in which a rotor turns in a magnetic field. The direct cu
Durchflussverteilung (Flow Sharing)
The flow rate distribution ensures a continuous fluid supply to the hydraulic consumers independent of the pump capacity. With the help of pressure compensation, the oil flow to the consumers is propo
Start pressure
Pressure necessary to start the functioning of a device or system (DIN 24 312).
Specific impedance
A special case of specific impedance is characteristic acoustic impedance Z 0, which is designated as the wave resistance of the medium. Z 0 is the quotient of the sound pressure and the sound particl
Signal generator
Device to deliver signals which change over time in the form of adjustable voltages with a sinusoidal, rectangular or triangular form, amongst others. Signal generators with computer-assisted, program
Protective filters
Protective filters are intended to protect the hydraulic devices against coarse contamination. They are installed upstream of devices sensitive to contamination in hydraulic circuits or in the control
Noise level L p
Logarithmic sound pressure p, in relation to the sound pressure p o The reference sound pressure p O (pO = 20 μPa) is equal to the noise pressure of the human hearing threshold level at 1000 Hz in dB.
Minutes
Agreements and regulations to ensure the safe and uninterrupted transfer of information between functional groups of an EDVA in accordance with the required functions. Minutes contain specifications o
Program execution sequence
Temporal relationship between the partial processes which help ensure a program is executed sequentially (DIN 44 300).
