Accurate pressure measurement is essential for maintaining safety, efficiency, and reliability in industrial processes. The VEGADIF 85 is a high-performance differential pressure transmitter designed to deliver precise measurements for liquids, gases, and vapors. Whether used for flow, level, density, or differential pressure monitoring, it provides stable and dependable process data even in demanding environments. Built with a high-precision metallic measuring cell, the VEGADIF 85 can detect extremely low differential pressures while offering excellent long-term stability and overload protection.
How Does the VEGADIF 85 Work?
The VEGADIF 85 measures the pressure difference between two process points using an oil-filled metallic measuring cell. One side of the sensor detects the high pressure while the other measures the low pressure. The transmitter calculates the difference and converts it into a standard output signal, enabling control systems to determine flow rates, liquid levels, or density with high accuracy. This measurement principle ensures reliable performance across a wide range of industrial applications.
