Even in deep tanks , ifm senses levels precisely
With the new LW2720 radar level sensor from ifm electronic , accurately measuring the level of liquid media in large tanks and vessels is no longer a problem ; this innovative sensor has a measuring accuracy of ± 2 mm at ranges up to 10 m . In addition , it is fully certified for use in hygienic areas , making it an ideal choice for food and pharmaceutical applications , including those that involve CIP and SIP operations .
The ground-breaking LW2720 measures levels using an FMCW radar-based system operating at a frequency of 80 GHz . This provides stable and accurate non-contact measurements that are unaffected by changing pressure , temperature and the presence of steam or condensates . In addition , the 80GHz operating frequency of the sensors provides a very narrow beam angle that gives a reliable level measurement even in applications where agitators , stirrers and scrapers are present .
