wheel detection and counting is essential to numerous
railroad monitoring and testing applications, including
railroad signal applications. Progressive Rail Technologies
has developed Wheel Detectors based on active non-contacting
proximity sensors that outperform conventional passive
style wheel detectors. Conventional wheel detectors
use passive detection technology that has an output
signal that varies dramatically with wheel speed.
Our experience with passive wheel detectors has
been that many wheels do not trigger the output
signal, thereby providing an inaccurate axle count.
Our Wheel Detectors provide a
consistent output signal that is independent of
train speed, direction, wheel profile or other
factors. The Wheel Detectors can be incorporated
into another monitoring system or function as
a complete axle counting/car identification system.
They are easily clamped to the base of the rail
without the need to drill holes through the rail.
