Indication accuracy
Accuracy with which a pointer instrument indicates. It is generally defined in accuracy classes. Here it is important to state whether the accuracy relates to the permissible error limits on the value
Chip
semiconductor material that contains an integrated circuit. Depending on the technology used, a chip with a size of a few square millimetres can house thousands or hundreds of thousands of gate functions
Bourdon tube
Measuring element for pressure gauges. This is a tube bent into a circular shape mostly with an oval cross-section that is clamped at one end. If pressure is introduced to the tube the free end moves
Control card
Printed circuit board (PCB) with electronic controller - at European manufacturers mostly in the eurocard format - that is used to control a proportional valve or servo valve. The control card is mostly
Accumulator pressure on temperature change
The accumulator precharge pressure (p0-> p0h) changes with the ratio of the increased or decreased temperature T0h to the original temperature T0. Calculate the accumulator pressure on temperature change
Valve dynamics
a defined frequency. To quantify the valve dynamics, it was agreed to investigate the valve system with sinusoidal signals. Thus valve dynamics can be described as the valve's response to sinusoidal input
Monitoring systems
be monitored and compare them to the stored target path. Monitoring systems are normally combined with diagnostic systems .
Position-dependent control signals
Electrical signals which are issued depending on the path travelled. Switches with a contacting or –– increasingly –– non-contacting method of engaging through to hall generators. However, optical switches
Multi-function valve
where the size of the flow or pressure is recorded by a sensor (e.g. proportional directional valve with ).
Amplitude modulation
The amplitude of a high frequency carrier frequency is modulated with a low frequency oscillating signal. Example: inductive position measurement in which the high frequency from an oscillator is modulated
