Differential Pressure Transmitter

Listing ID #3766191

Application area : The differential pressure transmitter VEGADIF 65 can be used universally for the measurement of liquids, gases and vapours. Typical applications are level measurements in pressurized vessels as well as flow measurements in combination with DP flow elements. Further applications are pressure monitorings on filters as well as density and interface measurements.

Your benefit

• Measurement of extremely small differential pressures through high precision measured value detection
• High reliability through integrated overload diaphragm
• Versatile use through a variety of measuring ranges and process fittings

Function : The sensor diaphragms are deflected by the acting pressures. The filling oil transmits the pressure to a semiconductor measuring bridge. The output signal, which is dependent on the differential pressure, is measured and further processed.
Materials : The process fitting is made of steel C22.8 (1.0460), Alloy or stainless steel 316L. The process diaphragm is available in 316L and high resistance materials Alloy C276 (2.4819), Alloy 400 (2.4360), Tantalum as well as Rhodium/Gold on 316L.
Housing versions :  The housings are available as single chamber or double chamber version in plastic, stainless steel or aluminium. They are available in protection ratings up to IP 68 (25 bar) with external electronics.
Electronics versions : The instruments are available in different electronics versions. Apart from the two-wire electronics with 4 - 20 mA or 4 - 20 mA/HART, two purely digital versions with Profibus PA and Foundation Fieldbus are available.
