Level Measurement up to +450 °C with New Guided Wave Radar

Dec 20 2012

Refractory ceramic and stainless steel combined with the latest level measurement technology – that’s the new VEGAFLEX 86. Developed by Vega (Germany) for extreme industrial applications, this GWR sensor measures liquids safely and reliably up to an operating temperature of +450 °C and a process pressure of 400 bar.

VEGAFLEX 86 is ideal for level and interface measurement of liquids. It delivers accurate and reliable results even in extreme temperatures from -196 to +450 °C and process pressures from -1 to +400 bar – in steam boilers as well as in bypass tubes or standpipes. Thanks to its ability to measure products with a minimum dielectric constant of 1.4 and higher, its application range is virtually unlimited.

The versions with cable, rod or coaxial probe and standard process connections such as threads from G1½ A (1½ NPT) and flanges from DN 50 (2") allow installation on any container or tank. The electronics versions are 4 ... 20 mA/HART, Modbus, Profibus PA and Foundation Fieldbus – to ensure simple connection to any process control system. In addition, the single and double chamber housings of plastic, aluminum and stainless steel make it possible to create an instrument version suitable for any process environment.

Setup wizards and new, intelligent signal processing functions also facilitate setup and commissioning and ensure stable, accurate readings. Since it was developed according to IEC 61508, the sensor meets the requirements of SIL2 and SIL3, when deployed in homogenous redundancy. A welded, gas-tight feed through (Second Line of Defence) brings additional safety to facilities handling hazardous materials. Last but not least, the standard approvals for explosion protection in gas and dust, for example ATEX and FM, round out the selection options.
