Description

The VEGADIF 85 Differential Pressure Transmitter uses a metallic measuring cell as the sensor element.  The process pressures are transmitted via the separating diaphragms and an oil filling to a resistance measuring bridge, using semiconductor technology.  It is a universal differential transmitter for measurement of liquids, gases and vapors. This instrument is currently installed on autonomous vessels.

Common applications include: differential pressure measurements of filters and pumps as well as level measurements in pressure vessels.
