Compact level sensors from VEGA with 80 GHz radar technology are said to provide reliable measurement results under all conditions. The VEGAPULS sensors, as well as switches and controllers, provide level, point level, and pressure measurement instrumentation.
Due to their physical measuring principle, VEGA ultrasonic sensors are inherently exposed to influences because the sound running time changes with temperature, e.g. due to solar radiation and gas composition.
Even in heavy fog, wind or rain, the sound waves are additionally attenuated and the measuring range further restricted. Radar sensors, however, are unaffected by temperature, pressure or vacuum and provide correct readings.
Radar sensors also allow a safe measurement up to the sensor antenna, even in case of flooding. Due to the process, flooding of the sensors occurs in some applications. Ultrasonic sensors are therefore often protected by mechanical flooding sleeves.
However, such components can easily become contaminated and impair the reliability of the measurement.
Radar sensors have no dead zone, do not require protective sleeves and measure reliably even in case of flooding.
