Staged clock control
Sequential, i.e. step by step switching control whose internal switching conditions depend on external signals (e.g. feedback from the process). One characteristic of the staged clock control is that
Single control for an actuator
Function unit for controlling a single (DIN 19 237). The single control for an actuator is the smallest (and lowest) function unit within the control for a process. It controls a single control elemen
Particle jet erosion
Wear on a metallic surface caused by solid particles contained in a liquid jet approaching at a high speed. Particle jet erosion results in smooth surfaces, as if they had been polished.
Stationary state
State of a system at the end of the transition phase (settling), in which the which determine the function of the system remain constant over time.
Signal parameter
The parameter of a signal , which carries the information. For example, the voltage is the signal parameter in the case of a continuous DC voltage. In the case of a frequency modulated AC voltage sign
Hose stretching
As hoses must be elastic in order to fulfil their task as a moving line connection, consideration must be taken to ensure that they also react elastically to excess pressure from the inside. Hoses for
Rest position
Of structural elements : Position of structural elements when they have no power or movable parts when not operated. Of a system : Position of actuators and control elements when they have no power.
Null-adjustment signal
Input signal (correction signal) for bringing a valve to hydraulic zero (DIN 24 311).
Instantaneous operating conditions
Conditions applying at a given moment in time (CETOP RP 100).
Pressure gauge selection switch
Pressure gauge selection switches are used to connect various pressure measuring points to a pressure gauge, assuming this is the preferred option. The pressure gauge may be installed in either the se
