Operating pressure

Difference between the opening and closing pressure for pressure-limiting valves (Figure S 15). It is created by the mechanical friction of the closing element, flow forces and the spring. It means th

Position assumed by the moving parts of a valve when the actuation energy is switched off ( centre position ).

Refers to the power produced by a flow rate Q at a pressure difference Δp: The theoretical hydrostatic power at the output side ignores any volumetric losses and hydromechanical losses. The effective

If the measured result is a function of one or more measured values , then the error on the measured result can be determined based on the law of error propagation . It describes the propagation of th

Provides information on the magnitude of the Δp of directional and check valves depending on the flow rate Q (Figure D 78) . The pressure drop-flow rate chart is an important parameter for assessing a

In position measurement with ultrasound (US), a US signal is issued, which is reflected by the moving body. The duration of the system measured in this way is proportional to the distance travelled. A

Systems in which only binary signals are transferred. They can contain, along with discontinuous two-point elements, also continuous elements provided the binary character of the overall system is ret

Machine controls whereby the tool follows the instructions taken from a template (or a sample workpiece) ( Figure K 31 ). The core element of a copying attachment during mechanical sampling is the cop
