Product catalogue: Differential pressure VEGADIF (Pressure, Density, Flow)

Product catalog summary

Differential Pressure Measurement Overview
In differential pressure measurement, pressures from two sides act on an oil-filled measuring cell, converting the differential pressure into an electronic signal. This method is applicable for measuring pressure, level, density, and flow of various media such as liquids, suspensions, gases, and vapors.

Advantages

Wide application range due to diverse measuring ranges and process fittings.
Capability to detect differential pressures as low as a few mbar.
Safe measurement of media with extreme temperatures when using a chemical seal.

Product catalogue: Differential pressure VEGADIF (Pressure, Density, Flow)-1

Differential pressure Differential pressure measurement In differential pressure measurement, different pressures act on an oil-filled, differential pressure measuring cell from two sides. The instrument converts the differential pressure into an electronic signal. Pressure, level, density and flow of liquids, suspensions, gases and vapours can be measured using the principle of differential pressure.  Wide application spectrum thanks to large selection of measuring ranges and process fittings  Differential pressure transmitters can detect differential pressures of just a few mbar With a chemical seal installed, media with extreme temperatures can also be safely and reliably measured
