Differential pressure measurement

In differential pressure measurement, different pressures act on an oil-filled, pressure difference measuring cell from two sides. The instrument converts the pressure differential into an electronic signal.
Pressure, level, density and flow of liquids, suspensions, gases and vapours can be measured using the principle of differential pressure.

The advantages

  • Wide application spectrum thanks to large selection of measuring ranges and process fittings
  • Differential pressure transducers can detect differential pressures of just a few mbar
  • With an installed chemical seal, media with extreme temperatures can also be safely and reliably measured

Function

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.

Series

VEGADIF 85 is a compact differential pressure transmitter. As an option, VEGADIF can be equipped separately with chemical seals.

Mounting

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.

Connection

The instrument is connected with standard two-wire cable.

Setup

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.
