2.2.2.4. Container level control sensors.
(1)
LEVEL
DETECTION SHEETING
(2)
SIGNAL
CONNECTOR
The
analyzer has
a capacitance
system to
control the
level of
the distilled
water
and waste
containers. For
this, there
is an emission plane (1) under the bottles where a signal
is injected through the connector (2). The base supporting
the bottles is above this. They have 2 rods that collect the signal and indicate the presence or absence of liquid.
