CARLO GAVAZZI CD34CNFLF Series Quick Manual

CD34CNFLFxxx
Capacitive sensor, Foreground Suppression
Description
The CD34.. capacitive sensor is designed for
detecting water-based (conductive) liquids through
a non-metallic container wall, and it automatically
adapts to various thicknesses of plastic or glass
walls.
The universal mounting brackets allow the sensor
to be fixed on various tubes or containers.
Strong, compact housing with IP69K ratings and
ECOLAB approval for wash-down applications.
The sensor will function out of the box in most
applications, and teach-in capabilities are available
for adapting the sensor to more challenging
applications.

Main functions
• Detection of water-based fluids inside a container or tube
without direct contact with the fluids.
• The sensor detects the liquids reliably while compensating
for residue film, moisture or foam build-up from liquids
such as water, milk, body fluids (blood), acid- or alkaline
solutions with conductivity as high as 50 mS/cm inside or
outside the container wall.
• Flexible and fast universal mounting bracket.
• The sensing principle detects only the level of the liquids
while ignoring foam, film or build-up that would cause
standard capacitive sensors to detect faultily.
