Radar level measuring sensors have special properties - they are rugged, abrasion proof, intelligent and suitable for virtually all products.
Vega has now developed the improved radar sensor for liquids, Vegapuls 42/44, using nano technology. The new antenna configuration makes the antenna considerably smaller than the original sizes. A better performance is achieved with better beam focusing with the small 4 cm antenna. These instruments are better suited to tanks with heating coils, agitators and baffle plates.
The sensors are available with 11/2" BSP/NPT threads, DN 50/80/100/150 or ANSI 2", 3" and 4" flanges. Output options are two-wire 4 to 20 mA current loop with (Hart), V.bus digital or Profibus PA, with a maximum of 15 sensors on a two-core line. The output signal is supplemented by an integrated or separate indication. The new sensors are approved for all Ex areas, pressure and temperature independent (-60 to 200°C) and suitable for most products, dependent on dielectric constant.
The sensors are calibrated with a credit card-sized detachable adjustment module (minicom), Hart handheld or with the self-explanatory adjustment programme VVO on a PC. The adjustment can be performed anywhere using the adjustment programme VVO; eg on the current loop in the switch cabinet, on the process control system or via a modem at home.

Level Measurement & Control
A municipal utility in eastern Germany operates a state-of-the-art wastewater treatment plant with sustainable sludge treatment. The ultrasonic signal was being partially deflected by the wind, leading to frequent false measurements and inefficient process workflows. The problem was solved by replaced the ultrasonic level sensor with KROHNE’s OPTIWAVE 1540 non-contact radar.
