Vega VEGADIF 85 differential pressure flow transmitter

The VEGADIF 85 is a differential pressure transmitter developed with safety in mind, and also offers the option of measuring differential and static pressure simultaneously with one instrument. Housed in a compact single-chamber case, the transmitter is designed for economic efficiency and installation with low space requirements.

VEGADIF 85 is now qualified and approved according to SIL-2 (SIL-3) for manufacturing processes that depend on certified components.

Differential pressure transmitters are characterised by their high accuracy in measuring flow rates, even at pressures of only a few mbar. They also handle extreme temperatures with no problem. Many different process fittings are available in conjunction with single- or double-sided chemical seals: denoted as CSS or CSB respectively.

VEGADIF 85 sensors are also equipped with a second, piezoresistive detector, making it possible to measure both differential pressure and static pressure in parallel. For example, they ensure a high degree of fail-safety in pipelines by determining the dynamic pressure and the superimposed static pressure at the same time: a measuring task that previously required two separate pressure transmitters.

Bluetooth configuration is now available as an option, and includes current encryption modes at the interface level (via PC or smartphone) as well as the necessary access codes that protect the sensor from unauthorised access.

The electronics used in VEGADIF 85 are 100% intrinsically safe and flameproof according to ATEX, IECEx and CSA. This means that the instruments can be safely adjusted at any time, even during operation in hazardous areas.
