non-invasive filling level control sensor
levelprox
LPRE-M30-AP6X2-H1141
●detection of liquids through the wall
of a container
●suited for a large variety of contai-
ner materials such as metal and
glass (plastic and other materials on
request)
●no medium contact, thus opening of
container not necessary
●Simple mounting via welding adap-
ter (also suited for retaining straps)
●automatic teach-in of ambient con-
ditions and selection of the operati-
on mode, i.e. reverberation or echo
mode, by connecting the teach line
to '+' or via the teach adapter VB2-
SP1 (accessory)
Wiring diagram
Function principles
Non-invasive ultrasonic sensors detect li-
quids through the metal wall of a container
or tank by means of high frequency ultraso-
nic pulses. In the reverberation mode, the
reflection of the interior container wall adja-
cent to the sensor are evaluated. Contami-
nation of or air bubbles in the medium
hardly effect operation, whereas residues
on the container inside will lead to unwan-
ted switching. In the echo mode, the sound
is evaluated that it reflected by the oppo-
sing interior wall. Residues on the container
inside will not cause any problems; but if
the container contains built-in components
such as stirring devices, or if the medium is
contaminated or contains air bubbles, this
operation mode may not be used.
