Absolute pressure transducer
Pressure transducer that can measure the absolute pressure . For this purpose the side opposite the pressure to be measured is hermetically sealed as a reference chamber (e.g. with a glass plate or glass [...] glass bushing). The reference pressure defined in this manner in the chamber can be a vacuum, but is not necessarily a vacuum. It is sufficient if the pressure is stable. The referencing of the measured
Single acting cylinder
pressure for the forward stroke only acts in one and the same direction ( ISO 1219-1 ). The piston can be returned by a spring, the inherent weight of the piston or external force. In principle, single-acting [...] effective piston area. Single acting cylinders are mostly equipped with plunger pistons . However they can also be formed by the single sided application of pressure to a differential piston .
Two-point controller
Non-continuous controller with two switching positions. The output signal can only take on 2 different values (neglecting the switching processes). Multi-position controller
Control range
Range within which the control variable can be configured, considering agreed values of disturbance variables, without jeopardising the functionality of the (DIN 19 226).
Addressing modes
ways of accessing registers and memory in the instruction set for a microcomputer. Such possible ways can be: implicit, absolute, indirect, relative etc.
Thin foil strain gauge
today instead of metal wire strain gauges. Thin foil strain gauges can be used as individual modules (see strain gauge ), however they can also be combined with calibration and compensation elements (Figure
Electro-hydraulic actuation
factor up to 105), which can be undertaken as quickly or, by installing a throttle valve in between, as slowly as required. On the usage of proportional solenoids the main valve can follow any ramp.
Bypass filtration
the filter. Regardless of how long the system operates for, it can keep on working until the oil is perfectly clean. Bypass filtration can also be used to rinse out the main system. Alternatives: filter
Detent
Moving parts of devices are fixed in one or more positions by a detent and can be moved to another position given an increased shifting force.
Primary noise control
All measures which a manufacturer of hydraulic pumps can take to keep the amount of noise generated as low as possible. Alternative: secondary noise reduction measures
