VEGAPULS 67 with plastic antenna |
In 2004 VEGA Grieshaber introduced VEGAPULS 68, the first radar sensor specially developed for level measurement of bulk solids. With a measuring range up to 70 m and wide temperature and pressure ranges (200 °C and 40 bar), it represented a real novelty in level measurement of bulk solids and has since established itself very well on the market. To close the remaining gap of standard applications with smaller measuring ranges and lower process demands, an additional instrument version, VEGAPULS 67, will be introduced at POWTECH 2007 from March 27th to 29th in Nuremberg.
The new VEGAPULS 67 finds application in areas where, for reasons of economy, ultrasonic instruments or capacitive probes were used until now. A new, innovative antenna system of plastic makes it possible to offer VEGAPULS 67 at a considerably lower price. Yet the tried-and-true pulse radar technology, with its high signal sensitivity and echo evaluation specially optimised for bulk solids, remains the heart of the instrument. The sensor is the ideal solution for applications in medium-sized silos up to 15 m high and covers the majority of standard applications in industries that process bulk solids – from the food industry to plastics warehousing right through to building materials production and processing. The optimised mounting concept makes it easy to adapt the small, light sensors to existing mounting apertures. And the two-wire technology enables problem-free replacement of obsolete measuring systems, since the existing connection wiring can be used. The sensor has all the relevant ATEX approvals for use in dust Ex hazardous areas.
