Measurement data processing
Section of a measuring device where what is received from the sensors in terms of signals is prepared, processed and output (displayed). The type and accuracy of measurement data processing must be ta
Access time
Time, which passes from the issue of an order until information contained in a memory is localised or read off. For example, in the case of magnetic plates, it is between 20 and 100 ms and considerabl
Circulation losses in hydraulic systems
In order to be ready for operation, hydraulic systems normally need the pump to continue running even if its flow rate is not needed at that time, e.g. in the loading phase of a working cycle. The pum
Suction pressure control
The delivery quantity of a piston compressor (related to the normal state) varies as the suction pressure is changed, with the suction valve raised more or less by a release valve during the compressi
Four-way valve
Valve with four controlled ports. For directional valves: Inlet, cylinder side A and B, outlet.
Comparability
The more dependent one becomes on determining parameters of fluid devices and systems through trial runs, the more important it is that these results are comparable. Otherwise, the different products
MZ engine (swashplate machine)
"Torque at the cylinder"; classification characteristic based on drive kinematics for axial piston swashplate (axial piston) pump or motors whereby torque is transmitted to the cylinder drum via the p
Overshoot
Short-term exceeding of a predetermined setpoint.
Hydraulic bridge rectifier
1. Arrangement whereby a combination of two half bridges results in a full (Wheatstone) bridge. This is the case, for example, with the control edges of continuously adjustable valves whereby deflecti
Error classification in measurements
A differentiation is made between systematic and random errors: Systematic errors : Are primarily caused by imperfections in the measuring instrument , the measuring procedure and the object measured.
