AquaMix MIXER MOISTURE SENSOR - microwave accuracy
AquaMix digital microwave on-line sensor
is highly sensitive to moisture changes in the mixer. Installed in
the concrete mixer floor or wall, it measures the material as it is mixed, passing the
ever-changing moisture value to the control system for measurement and
control. The AquaMix sensor's faceplate has to endure the harsh abrasion
of the aggregates as they mix; consequently, it uses high-tech Silicon
Nitride ceramic, almost diamond hard and extremely tough. AquaMix's
faceplate is harder, thicker and tougher than anything else in the industry.
It lasts for the life of the sensor, making it the toughest,

The AquaMix sensor's standard mount is a square plate that is welded
onto the outer surface of the mixer, with threaded rods that engage with
the sensor's flange. Nuts on these rods move the sensor up or down
to level its faceplate as the mixer's liner wears. A special epoxy
"Super grout" fills the gap around the sensor, preventing stones being
caught and chipping the faceplate.

is an elegant solution to a difficult problem. The AquaMix Glider
acts like a ski or toboggan, allowing the sensor to glide on the surface
of the mix while measurements are being taken. When measurement is
finished, the Glider lifts out of the mix, reducing wear and buildup
until it is time to measure the next batch. The "ski" holds the
sensor faceplate at a constant downward pressure in the mix, controlling
density and eliminating air pockets that destroy accuracy. The
result is a highly stable, accurate reading that allows fast assessment
of the moisture either before or during the addition of water.
The ski is fabricated from chromium
carbide cladded steel, giving wear similar to the AquaMix's
Silicon Nitride faceplate and ensuring many years of service before
replacement. When service is required, all parts are replaceable.
