In 2004 VEGA Grieshaber introduced VEGAPULS 68, one of 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), VEGAPULS 68 represented a real novelty in level measurement of bulk solids and has since established itself well on the market.
To close the remaining gap of standard applications with smaller measuring ranges and lower process demands, an additional instrument version, the VEGAPULS 67, is available.
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 lower price.
Yet the tried-and-true pulse radar technology, with its high signal sensitivity and echo evaluation 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 approvals for use in dust Ex hazardous areas.
