The Nordson Level Controller is designed to integrate into a powder
recycling system to control the addition of powder from a virgin supply to
the powder hopper.

P/N 768606A
The Nordson Level controller automatically monitors and controls the
feed of virgin material to powder coating systems. It eliminates the need
for manual powder filling of the hopper, minimising spillage and dust
hazards.
By maintaining a constant level of powder in the hopper, this provides a
constant gun output and film thickness.
The unit is primarily designed for use with the Nordson feed from the box
system, it has an electric supply for a vibrator, a regulated air supply for
the Nordson transfer pump and comes complete with a simple to mount
sensor for fitting to the side of the powder hopper.
Internal to the unit are connections for a remote annunciator, started
when the powder level in the hopper has not been restored before a
preset time has expired. A mute control on the front panel allows the
operator to silence the alarm, while an integral illumination of the switch
provides indication that the powder level has not been restored in the
hopper.
The Level controller may be installed in both new and retrofit systems. It
is supplied in a Nordson Versa Style casing which may be removed to fit
the controller into Nordson 19” rack units.
