Field of application is designed for level detection in tanks and dry-run protection of pumps by empty pipe monitoring. It detects liquid, pasty or oily media, but also solid-bulk materials like flour or plastic granulate. The LBFI is capable of media differentiation by distinguishing the specific properties, such as oil, water, foam and liquid.reliable performance is assured in any mounting position (from top, bottom or side). Depending on the desired process connection, different mounting options are available. Corresponding mounting aids and adaptors for conventional process connections are available as an accessory.two switching outputs are available with dedicated switching windows. The switching function is programmable as PNP, NPN or digital (push-pull) polarity, as well as the switching logic like Normally Open (NO), Normally Closed (NC) or inverted. in its default configuration covers a major part of potential applications. Where customer-specific configuration is required because of demanding media (e. g. foamy or adhering), qteach, remote teach or the FleProgrammer 970 allows for easy optimation of the switching windows. The measured data can be visualized on a PC for further parameter adjustment, for eample time constant of a damping function and inverted switching output logic. Measuring principle An electrode inside the sensor tip builds a capacitor together with the surroundings. The medium with its dielectric constant (DC value) is defining the capacitance value. A resonance circuit is created in combination with a coil in the sensor head. Switching signal tripping is according to the measured resonance frequency and the programmed trigger thresholds.
