The 8112 is a vibrating level switch for liquids,using a tuning fork for level detection.It is designed for industrial use in areas of process technology and can be used in liquids.Typical applications are overfill or dry run protection.The Type 8112 is available with different sensorlength using tube extension. The rightlength can be adapted thanks to a lock fitting.Due to the simple and rugged measuringsystem, the 8112 is virtually unaffected by thechemical and physical features of the liquid.It works even under unfavourable conditionssuch as turbulence, air bubbles, foam generation,buildup or varying products.
