Safety control circuits
Circuit arrangement to prevent undesired actuations or to protect against overloading. The safety elements required for this, such as valves with a redundant design, electrical monitoring of switching
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
Safety circuit
Circuit, which prevents undesired and/or hazardous operating states. The scope and design of the safety circuits for certain systems are prescribed by the German Institutions for Statutory Accident In
Safety regulations
In terms of fluid technology there is no closed regulatory system in terms of safety technological requirements. Rather, these are distributed over a series of rules, regulations and standards of the
Safety of a system
In general : The term "safety" should only ever be used within the meaning of preventing a risk primarily to people and not within the meaning of the reliability of a system (cf. operating safety). Th
Characteristic curve
General : Graphically represented mutual dependency between two operating variables, often with a constant third being used as the parameter. Example: In Figure D79, the flow rate Q is applied to a co
Correction of characteristics
Changing the stationary characteristic curve for a device by modifying the input signal in order to compensate for non-linearities , reduce hysteresis and the like. This kind of correction can involve
Performance map
Graphically represented mutual dependency between two operating variables, with one or more variable parameters being used as parameters. This kind of performance map can provide a complete overview o
Natural angular frequency ω o
Derived from the natural frequency f o as follows: ω o = 2 π · f o
Natural frequency fo
Natural frequency is the natural frequency of a second order delay element designed to be damping-free, If a system capable of oscillation such as a spring-mass system is prompted to oscillate as a re
