New SIL pressure transmitter double the safety level of processes

VEGADIF 85, a differential pressure transmitter developed especially with safety in mind, is VEGA’s new component for reliable, continuous control and monitoring of industrial processes. Its strengths lie not only in functional safety, but also in the option of measuring differential and static pressure simultaneously with just one instrument. Contained in a compact single-chamber housing, the transmitter is designed for economic efficiency and installation with low space requirements. These features are flanked by particularly simple, intelligent operation: Which is a real plus in terms of error avoidance.

VEGADIF 85 is now qualified and approved according to SIL-2 (SIL-3) for manufacturing processes that depend on certified components, simple, user-friendly operation and permanently transparent processes. It can be adjusted conveniently via cable connection as well as wirelessly via Bluetooth. Its measured values can be integrated into the existing processes in no time at all – always in a form suitable to the respective conditions and requirements.


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

Bluetooth is also available as an option for this new generation of differential pressure transmitters. Since it is part of the tried-and-trusted modular VEGA instrument platform plics®, it implements safety precautions at various levels already proven in the field. These include current encryption modes at the interface level, i.e. via PC or smartphone, as well as the necessary access codes that protect the sensor from unauthorized access.
By the way, Bluetooth is also something for older systems: the current display and adjustment module PLICSCOM is downward compatible for the majority of VEGA measuring instruments manufactured since 2002 and now operating in the field.
