Signal
Physical variable to represent information, wherein selected carry information. The representation may relate to the transfer, processing and storage. It is only permitted to speak of signals in the c
Signal state
Any possible value of a digital signal. Example: The binary values O or L are allocated to certain voltage ranges or switching states (EDIN 19 226 T 5).
Signal path
Graphical representation of the transfer of a signal between two or more functional elements or operating materials (DIN 40 719 T 61).
Operating loads
Loads on a system or parts of a system result from the operating conditions .
Operating modes of drives
Drives have not only a driving function, they also provide braking (e.g. deceleration or lowering braking). In addition, the direction of rotation can also be reversed. The combination of these possib
Operating mode of a control
Characterisation of the nature and scope of the intervention in a control system by the operator and by feedback from the system to be controlled. Here in accordance with DIN 19 237 a differentiation
Actuating methods for valves
All valves must be moved by external forces from a rest position to a working position . There is a series of ways of achieving this action that in DIN-ISO 1219 are divided into: manual actuation, mec
Actuation element
Component that actuates a device (e.g. valve ). This can be a lever or cam ( mechanical actuation ), a solenoid or electric motor ( electric actuation ) or a piston or cylinder ( pressure actuation ).
One-way trip
Device for actuation in only one direction. In the other direct there is no actuation (CETOP RP 100).
Beta value (β value)
Measure for the effectiveness of a filter. The value is a ratio that is defined by the number of particles before and after passing through the filter with a specific pressure drop (Figure B 13) : The
