The α values is defined by the multipass test according to ISO 4572. It is a measure of the total quantity of ACFTD supplied to the filter element until the permissible final pressure difference is re

The drive contains only one pump that provides its flow rate to one or also more loads. Opposite: multi-circuit systems

Controller on which the input and are analogue signals . Also controller with analogue, and with continuous and time-continuous , i.e. progressive input and output signals today often have a digital c

Process to monitor the operating state of a hydraulic system or individual devices with the aid of temperature and pressure measurements . It uses the hydraulic fluid to carry the information and is b

General : Depending on the nature of the changes in the pressure, a differentiation is made between static and dynamic pressure measuring procedures. Static pressure measuring procedures are when cons

During the operation of a hydraulic system the particles of dirt that occur in the pressure fluid . They are either Added from the outside, e.g. due to leaks, a poor breather filter or are due to inad

Ability of a valve to transfer signals at a defined frequency. To quantify the valve dynamics, it was agreed to investigate the valve system with sinusoidal signals. Thus valve dynamics can be describ

Discrete signals with a finite number of value ranges for the signal parameter where each value range is assigned as a whole to a specific item of information. Digital signals can also have multiple p

The term block diagram should no longer be used, instead signal flow diagram should be used DIN 44 300 part 4.

Before any evaluation of measured values of a measured variable , a test should be conducted as to whether the measurements have been taken under the same test conditions and independently of one anot
