Differential pressure measurement
In differential pressure measurement, different pressures act on the two sides of an oil-filled differential pressure measuring cell. This converts the pressure differential into an electronic signal. Differential pressure measurement is used to measure pressure, level, density and flow of liquids, suspensions, gases and vapours.
VEGADIF 85 is a compact differential pressure transmitter. As an option, VEGADIF can be equipped separately with chemical seals.
Threaded or flanged connections allow installation in a variety of process fittings on vessels and pipes. The pressures are transmitted to the sensor via a pipeline or chemical seal.
The instrument is connected with standard two-wire cable.
As soon as a plausible measured value is found, the corresponding current is output on the signal line. The value corresponds to the current differential pressure.
