Level Switch

The Level Switch LBFS designed to detect levels in tanks, mediaseparation and provide empty-pipe detection or dry-run protection forpumps.A high frequency sweep signal is radiated from the sensor tip into thetank. The media will act as a virtual capacitor, which together with acoil in the sensor head, will form a circuit creating the switch pointsignal. This virtual capacitance will depend of the di-electric value ofthe media.Two output signals are available, Normally Open (NO) and NormallyClosed (NC). By means of the FlexProgrammer 9701, a damping ofthe output signal can be activated in case of a fluctuating media level,e.g. during tank filling. Additionally the output signals NO and NC canbe reversed.The measurement is precise and unaffected by the mounting positionin the tank. In the Flex-software a compensation for foam, bubbles andcondensate as well as sticky media can be set.The Flex-software also features an adjustment facility making the userable to adjust the sensor to a specific media.The Level Switch LBFS measures liquids such as water and oil. Evendry medias can be measured, eg. coal dust or plastic granulate.Level Switch LBFS can be delivered with PNP output as well as NPNoutput.The process connection can easily be sealed by use of Teflon Tape orby use of special welding adapter for the hygienic edition.
