Product Description
Optical level sensor with un-
modulated, infrared light for
the detection of liquids. Fit-
ted with built-in amplifier.
Transmitter and receiver are
completely self-contained in
solid plastic housing designed
for mounting into container
wall. VP01/02 are available
in a Polysulphone housing
resistant to most acids and
bases. VP03/04 are avail-
able in a Polyamide 12
housing resistant to various
solvents.
