Product catalog summary
Overview
The document provides detailed information on the VEGAFLEX series of Guided Wave Radar (GWR) sensors, which are used for level measurement in liquids and bulk solids. These sensors are capable of detecting interfaces between two media and are reliable under high pressure and extreme temperatures. They are suitable for both simple and aggressive media, including applications with stringent hygiene requirements.
Measuring Principle
The GWR sensors operate by emitting high-frequency microwave pulses along a cable or rod. These pulses are reflected by the medium's surface, and the level is calculated based on the pulse's travel time compared to the programmed tank height.
Advantages
GWR sensors are unaffected by noise, pressure, temperature fluctuations, density changes, foaming, steam, or dust. They offer simple system design and engineering, with menu-driven adjustment routines for easy setup.
Product Specifications
  • VEGAFLEX 81 & 82: Suitable for all kinds of liquids and bulk solids, with a measuring range of up to 75 m for cable probes and up to 6 m for rod probes. They operate within a temperature range of -60 to +200°C and a pressure range of -1 to +40 bar. Signal outputs include 4-20 mA/HART, Profibus PA, Foundation Fieldbus, and Modbus.
  • VEGAFLEX 83 & 86: Designed for aggressive liquids and extreme conditions, with a measuring range of up to 32 m for cable probes and up to 6 m for rod probes. They handle temperatures from -196 to +450°C and pressures from -1 to +400 bar. They also support the same signal outputs as the other models.
Approvals and Benefits
All models have multiple approvals, including ATEX, IEC, FM, CSA, and more. They offer comprehensive diagnostic options, maintenance-free operation, and shortenable probes for flexibility in planning.

Guided Wave Radar-1

Level l Guided Wave Radar Area of application The GWR sensors of the VEGAFLEX series are suitable for level measurement in liquids and bulk solids. In liquids, they can also detect the interface between two media. They measure liquid levels very reliably, even under high pressure and extreme temperatures. They can be used in simple as well as in aggressive media and are also suitable for applications with stringent hygiene requirements. The sensors are able to measure light and heavy bulk solids with absolute reliability, even in the presence of dust and noise. Measuring principle High-frequency microwave pulses are coupled onto a cable or rod and guided along the probe. The pulses are reflected by the surface of the medium. The instrument calculates the level from the running time of the radar pulses versus the programmed tank height. Advantages GWR sensors operate independently of noise, pressure or temperature fluctuations and are also completely unaffected by changes in density, foaming, steam or dust. Buildup on the probe or on the container wall hardly affects the measurement. This allows simple, straightforward system design and engineering. The menu-driven adjustment routines enable simple, time-saving and confident setup.
