VEGA Australia

22/10/14 - VEGA Australia introduces the VEGAPULS 69, the new radar sensor recommended for reliable level measurement of bulk solids. VEGA has been the market leader in the radar level measurement sector for almost 20 years.The new VEGAPULS 69 is an all-round radar level measuring instrument for bulk solids. Operating at a frequency of 79 GHz, the level transmitter enables considerably better focusing of the transmitted signal, which helps reduce the issue of background noise in containers and silos with many internal obstructions. The VEGAPULS 69 enables reliable measurement even with complex internal structures.New microwave components allow the sensor to detect even the smallest of reflected signals. The reliable level measurement enabled by the new radar sensors facilitates an extremely broad application range in the bulk solids industry and also opens up new application areas. For instance, products such as plastic powders or wood chips that till recently were very difficult to measure because of their poor reflective properties can now be measured with very high reliability. VEGAPULS 69 radar sensors have a measuring range of up to 120 metres and an accuracy of ±5 mm, providing sufficient performance capability even for tasks such as level gauging in mine shafts or distance measurement on conveyor systems. Despite its large measuring range, the sensor is also an ideal solution for small hoppers or containers, with the different antenna designs offering the optimum solution to meet diverse application needs. VEGAPULS 69 sensors are available in two versions: one has a simple, light plastic antenna and the other, a lens antenna integrated in a flange. The flange version has a swivel holder made of high quality stainless steel, which enables the antenna to be set conveniently.Key benefits also include innovative lens antenna completely unaffected by dirt and build-up to guarantee maintenance-free operation even in harsh environments; and an intelligent App for smartphones simplifying setup and commissioning to allow quick and easy alignment of the sensor on a swivel holder.

17/09/14 - Electronic differential pressure transmitters from VEGA Australia are recommended for level measurement of liquid gas stored in spherical tanks in refineries.Typically a mixture of propane and butane, liquid gas is a by-product of petroleum refining, and is considered an ideal fuel for cars (LPG) and for heating with its high energy content. Measuring the liquid levels in these storage tanks is a challenging task because liquid gas has physical properties that are not conducive to measurement, leaving only a few measuring methods suitable for the purpose. For safety reasons, two redundant measurement setups and a separate overfill protection system are always required. All measuring systems must also be SIL2 qualified.Differential pressure transmitters with capillary systems are often used to measure the liquid levels in these tanks. Due to the huge dimensions of the spherical tanks, extremely long capillary tubes are required; when exposed to outdoor temperatures, these tubes influence the measured values significantly.To measure liquid gas in a spherical storage tank measuring 21m in height and a tank pressure of 300 mbar, with medium temperature being -10°C ~ 0°C and ambient temperature being -20°C ~ +40°C, VEGA recommends electronic differential pressure measurement with VEGABAR 82 and 86 for this measurement task. In this master/slave system, the capillary tubes are replaced by an electrical connection. In contrast to capillary systems, electronic differential pressure transmitters are not affected by the medium temperature or the ambient temperature. Even small level changes are recognised immediately, enabling the user to get accurate and reliable measurements at all times. The absence of capillaries in the process eliminates the need for mechanical protection and maintenance of these components. The sensors deliver the medium temperature and the static pressure as measured values simultaneously. Key user benefits of VEGABAR electronic differential pressure transmitters include high operational reliability through reliable, accurate readings; cost-effective instrumentation without capillaries and protective covers; and output of medium temperature and static pressure with fewer tank fittings, simpler installation, and elimination of superfluous measuring points.

26/06/14 - VEGA Australia announces the release of a new range of standardised signal conditioning instruments and isolating modules.The new VEGATOR series 100 features a standardised housing platform designed with a universal electronics and adjustment concept for signal conditioning instruments and isolating modules. Following a modular concept, all channel numbers and functions are clearly structured to simplify selection, while the order codes, operating manuals, connectors and temperature ranges have all been standardised across the entire range of devices. All units of the VEGATOR 100 series have identical dimensions with the device width measuring a standard 20mm, even in the 2-channel models. The clever design ensures that the hazardous areas, Ex and non-Ex zones are safely isolated from each other.Vega follows up series 110 and 120 modules with the new VEGATOR 140 transmitter power supply units with limit switch function. The active and passive isolators VEGATRENN 140/150 and the conductive signal conditioning instruments VEGATOR 130 will also be introduced soon.

01/05/14 - The most versatile of the VEGABAR 80 series pressure transmitters from VEGA Australia, the VEGABAR 82 sets new benchmarks in ceramic pressure instrumentation with its standout features.VEGABAR 82 process pressure transmitters deliver excellent thermal shock resistance and significantly reduced moisture sensitivity, and are rightly known as the all-rounders in the VEGABAR 80 family.VEGABAR 82 features an innovative ceramic CERTEC measuring cell developed and produced by VEGA. This highly versatile instrument with oil-free ceramic cell can cover two-thirds of all applications in the process industry. Key benefits of VEGABAR 82 ceramic pressure transmitters include high resistance of the ceramic pressure cell to temperature shocks; complete elimination of condensation sensitivity in the sensor; ability to handle temperatures up to +130°C; extremely high factor of 200 overload resistance; and measuring range of 25 mbar without using electronic turndown up to 100 bar. Its ability to handle high temperatures makes it suitable for use in the food and beverage industry.
