Control memory
Functional unit within a control , which stores programs (program memory) or other data (data memory) in a digital representation (EDIN 19 226 T 5).
Priority valve
Valve which gives priority to a part circuit. This might be, for example, a which waits until a certain pressure is reached in circuit I before connecting circuit II and then disconnects it once the p
Bulk modulus
Parameter for the volume elasticity of a fluid, comparable to the modulus of elasticity of solid substances. Unlike the modulus of elasticity, however, the (genuine) bulk modulus is not a constant val
Slave piston principle
Function principle in which a small pilot piston is deflected, the main control piston then follows by means of pressure actuation as long as the actuation lasts. As a rule the pilot piston is in the
Natural angular frequency ω e
Given by the natural frequency as
Differential pressure
Measured variable for the pressure difference between p 1 and p 2 . The differential pressure can be positive or negative, depending on whether p 1 is greater than p 2 or smaller than p 2 (Figure D 23
Continuous operating conditions
Are characterised by numerical values of the individual variables with which the system can be operated without interruption (CETOP RP 100).
Code
Agreed code for the translation of information available in a stipulated form into a different form while maintaining the information content. A code can also be a code for an agreed character set tha
Bourdon tube
Measuring element for pressure gauges. This is a tube bent into a circular shape mostly with an oval cross-section that is clamped at one end. If pressure is introduced to the tube the free end moves
Binary system
Process for the representation of decimal numbers as binary numbers (dual numbers) and vice versa. Example: (diagram)
