Nominal power
Power of a device (pump, motor, valve ) within defined parameters.
Quantisation error
Error, which arises when quantising analogue sizes, as only a limited resolution is possible, which causes a systematic error . It is equal to half of the change of the input voltage needed to change
Accumulator
1. A term only used infrequently these days for hydraulic accumulator . 2. Register in a computer system for carrying out mathematical operations, this register contains an operand prior to carrying o
Input signal
Signals on a transfer element that control the on this transfer element (DIN 19 226). Transferred to continuously adjustable valves the input signal is the physical variable, e.g. current or voltage,
Algorithm
General : Specification or process that follows a specific scheme and that solves a problem. This can be a mathematical formula, a flow diagram or a program. In control technology : Algorithm is used
Dual loop control circuit
Control loop, which in addition to the control variable , a further auxiliary variable (e.g. velocity or acceleration) in a subordinate minor loop is fed back.
Word length
Also known as the data length, this is the number of bits that can be jointly transferred and processed in a computer. It is used to classify microprocessors and microcomputers. There are currently: 4
Delay element
Elementary or parallel-connected transfer elements with additional time delays. They are marked Tk, where the index k states the order of the delay (according to Din 19 226 Part 2).
Underpressure
Previous term for pressures beneath the atmospheric pressure. According to DIN 1314, underpressure should no longer be used to name a variable, but only for the qualitative description of a state. As
