VEGA level transmitters in open-cast mining: Precise measurement under harsh conditions with 80-GHz radar

The 80-GHz radar technology used by VEGA enables non-contact measurement, keeping the transmitter at a safe distance from the actual measuring point. This minimises the risk of damage or interference from the production processes themselves. What is more, VEGA radar transmitters are unaffected by temperature fluctuations, vacuum, or pressure, and totally non-sensitive to dirt and dust. 

While dust, vibration, stone chips and changing weather conditions greatly afflict ultrasonic transmitters and cause malfunctions, such conditions are no problem for VEGAPULS BASIC level transmitters. The instruments are robust and hard-wearing, and operate with great accuracy – around the clock. Thanks to the high frequency of 80 GHz, the radar beam can be focussed very tightly and directed with pinpoint precision onto the bulk solid material. This allows VEGA radar transmitters to measure even in narrow shafts, through dust clouds or in vessels with internal fixtures. Even dust-covered antennas have little effect on the measuring result.
