Angle measurement
Angles can be measured using analogue or digital methods. Analogue methods include rotating condensators, the capacity of which is a measure of the angle of rotation or a rotating potentiometer. Tacho
Transfer function
Mathematical formulation ( Laplace transformation ) of the transfer behaviour of a system (DIN 19 226 Part 2).
Controlling in the signalling area (signal flow)
Collective term for all techniques and aids necessary to manipulate the control elements of the power flow such that they can perform their functions according to the task formulation. The information
Coil impedance
The complex ratio of the control coil voltage and current. The coil impedance is a function of the frequency of the signal amplitude and other operating conditions, but it can be estimated using the O
Supply pressure
Pressure at the inlet to a device or a system created by an auxiliary system (DIN 24 312).
Safety risk
This is described by a statement of probability, which summarises the expected frequency of occurrence of undesired events in the case of a defined technical process or state and the expected scope of
Signal forms
Signals may have an analogue, digital or binary character. In addition, they may have a continuous value, i.e. the signal parameter can take on all values within an interval; have a discrete value, i.
Switching power
Minimum power on the switching element required to actuate a valve (CETOP RP 100).
