DIN 24 312 and DIN 2401 contain a summary of the pressure ratings used in the area of fluid technology as well as the preferred pressure values in this area. The ratings should be used, as far as poss

Pressure-limiting valves limit the inlet pressure by opening the outlet to the tank via the function element (which is closed at rest) on reaching the set pressure. This action occurs by opening again

Measuring instrument that acquires at its input the measured variable "pressure" and outputs a corresponding electrical signal on its output. The pressure transducer therefore comprises a housing with

Device that, by applying pressure to a piston, indicates whether the pressure in the medium is above or below a pre-defined value (CETOP RP 100).

Time-dependent pressure change from a lower value to a higher value (DIN 24 312).

Velocity at which the pressure in a device increases. It is measured in bar/s and defines, e.g. on pumps, the amplitude of the pressure pulsation-induced oscillations and with it also the amount of no

Time-dependent pressure change from a higher value to a lower value (DIN 24 312). The pressure drop is generally referred to a device or a section (e.g. pipe).

Throttle is the general term used for a physical flow resistance. Throttle is therefore the generic term for orifice and nozzle . Flow resistances with a largely linear dependence of the flow rate on

Sum of all the pressure losses that occur at the various throttling points in a system (i.e. wherever there is a cross-section constriction). Another type of throttle loss occurs if in a system with c

Flow valve with fixed or adjustable throttling cross-section. Its flow is dependent on the pressure difference at the throttle: the smaller the pressure difference Δp between the (constant) inlet pres
