100,000 bulk solid radar sensors from VEGA installed worldwide

The 100,000th bulk solids radar instrument is a VEGAPULS SR68. The landmark sensor went to Bhler in Switzerland, who are using it for level measurement in a 25-metre-high cement silo. VEGA Grieshaber KG launched VEGAPULS 68, the first radar sensor specifically tailored to applications in the bulk solids industry, on the market in 2004. Compared with radar sensors for liquids, the bulk solids radar sensor is capable of detecting and measuring signals a 1000 times smaller - signals that were previously masked by "noise'.

Such two-wire loop powered sensors have since become "the' alternative to maintenance-intensive mechanical "plumb bob' systems, or ultrasonic sensors, which require a clear, dust-free view to the product. Thanks to simple application parameters, only a few settings are needed to fine-tune the radar sensor to the measurement. The result is reliable reading, completely independent of dust, filling noise, strong air currents and high temperatures, with no loss of echo issues.

Three sensor variants ensure the advantages of non-contact radar technology can fit all kinds of applications, as well as measuring and temperature ranges. VEGAPULS 68 is optimised for ranges up to 75m and temperatures up to 400degC, while VEGAPULS 67 and VEGAPULS SR68 are designed for standard applications. One basic technology covers a wide spectrum - from level measurement in clinker coolers at 1500degC, or grain silos, to level monitoring in rock crushers.
