Until now, the principle of a vibrating level switch has been limited to process conditions up to a maximum of 280°C and 100 bars. By using a new drive for the tuning fork of its Vegaswing 66, this company has made it possible to operate over the temperature range from –196 to 450°C and pressures from 0 to 160 bars. The integrated analysis and monitoring capabilities allow certification according to SIL2 and steam boiler regulations. The application range extends from distillation columns in the oil-and-gas industry, to high- and low-water limits in steam boilers, and cryogenic applications in gas tanks for LNG and nitrogen. — Vega Grieshaber KG, Schiltach, Germany
