LBFH 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 our or plastic granulate.
The LBFH is capable of media differentiation by distinguishing the spe-
cic properties, such as oil, water, foam and liquid.Reliable performance
is assured in any mounting position (from top, bottom or side). Depen-
ding 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. CleverLevel

LBFH in its default conguration covers a
major part of potential applications. Where customer-specic congura-
tion is required because of demanding media (e. g. foamy or adhering),
qTeach, remote teach or the FlexProgrammer 9701 allows for easy opti-
mation of the switching windows. The measured data can be visualized
on a PC for further parameter adjustment, for example time constant of
a damping function and inverted switching output logic.
Field of application
An electrode inside the sensor tip builds a capacitor together with
the surroundings. The medium with its dielectric constant (DC value)
is dening 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.
