The VEGADIF 85 is a universal differential pressure transmitter designed for measuring liquids, gases, and vapours in a wide range of applications. Typical use cases include:

• Level measurement in pressurized vessels
• Flow measurement when paired with pressure transmitters
• Monitoring filter pressure
• Density and interface measurements

Key Features:

• High Precision: Measures very small differential pressures with high accuracy.
• Reliability: Integrated overload system ensures dependable operation.
• Versatility: Offers a variety of measuring ranges and process fittings, suitable for diverse applications.

Operating Principle:

The VEGADIF 85 utilizes a metallic measuring cell with a piezoresistive sensor element. Pressure differences are transmitted through separating diaphragms and an oil filling to a sensor element, which converts the pressure into an electrical signal. It also measures the temperature of the measuring cell and static pressure on the low-pressure side, providing additional output signals for comprehensive data.

Materials:

• Process Flanges: Stainless steel 316L, Alloy 276, or Superduplex
• Process Diaphragm: Stainless steel 316L, Alloy C276, or Tantalum for high resistance to corrosion.

Housing Options:

• Available in single or double-chamber designs made of plastic, aluminium, or stainless steel.
• Protection ratings up to IP68 (25 bar) with external electronics, and IP69K for demanding conditions.

Electronics Versions:

• Two-wire electronics offering 4 … 20 mA or 4 … 20 mA/HART outputs.
• Digital versions with Profibus PA, Foundation Fieldbus, and Modbus.
• Additional electronics options for double-chamber housings, such as radio modules, extra current outputs, or power packs.

Approvals:

The VEGADIF 85 has worldwide certifications, including for use in hazardous areas, on ships, and in hygienic environments. Technical data may vary depending on the approval and safety instructions provided for specific versions.

This product is highly customizable and suitable for a broad range of industrial applications requiring reliable and precise differential pressure measurement.
