Water in oil
If water enters hydraulic oil (e.g. condensation or through an external contamination), this has unwanted consequences as it accelerates the ageing of the oil, increases the corrosion of metallic surf
Signal technology
Collective term for all measures, procedures and devices, which are required to use given input signals to obtain the necessary for the process by way of suitable signal processing . This applies to t
Amplifier card
All components required to activate a continuously adjustable valve (not just for amplifiers) are housed on a card (normally with a European format) ( Figure V 19 ). This includes not only control amp
Compressibility factor
Occasionally used inverse of the bulk modulus :
Driver
Functional element, which converts a low-voltage signal into a signal with a higher power. That applies both to the power section and the signal processing, where a voltage signal is converted into a
Temperature measurements in hydraulics
The temperature of the hydraulic fluid in hydraulic systems can be measured either with simple measurement devices (thermometer) or with a measuring device that issues signals to the control unit. The
Flow diagram
Aid used to clarify, prior to the definition of a control or preparing a computer program, the logical sequence of the solution by defining graphically the order in which detailed tasks are to be unde
Flow sounds
High-frequency sounds created if non-stationary flow processes form at throttling points. That is primarily the case where the flow state is determined by the forces of inertia. The associated speed a
Electronic Flow Sharing
"Electronic Flow Sharing" describes the flow rate distribution of the pump flow to the individual consumers in a hydraulic system by means of electronic control. Flow sharing addresses the problem of
