| Sensing Rocks in Crusher Bowls |
|
Ultrasonic sensors provide an ideal solution for
aggregate level monitoring inside harsh crusher bowls.
Accurate and reliable level monitoring and control
is vital to feeding and maintaining a steady amount
of aggregate product into each crusher. If too little
rock is fed into the crusher the rock will not be
crushed to desired size and the crusher is not being
used to capacity, resulting in additional steps and
lower productivity. If too much rock is fed the
crusher will overflow and excessive wear to parts
occurs. Ultrasonic sensors provide the reliability
and accuracy to help to maximize crusher
throughput and overall productivity.
APG's IRU-5280 ultrasonic
sensors function extremely well in harsh aggregate
applications by virtue of their non-contact operation,
and provide very stable and accurate sensing of both
small and large rocks. They provide superior operation
when compared to mechanical devices in similar
applications because they do not wear out or become
damaged from contact with the product. Additionally,
unlike other mechanical level sensing devices they are
not affected by target surface, color or translucency. As
a result, they provide extremely reliable and accurate
operation, and require little to no maintenance. |

| Self-Contained Ultrasonic Sensors |
| Programming and Operation |
The software options embedded in the
microprocessor controlled sensor offer special
functionality to address the issues that might be faced
by ultrasonic sensors in aggregate level monitoring.
Dust, acoustic noise from machinery and moving rock,
varying surface angles and sizes, varying ambient
(outdoor) temperatures can all be accommodated by
appropriate configuration of the ultrasonic
sensor. |
