We know that even with a quality belt, a soundly engineered system and an effective preventative maintenance program,
any conveyor system can suffer belt rips. As conveyors get longer, 3,000 HP and higher drives become more common,
generating tensions in the hundreds-of-thousands-of-pounds range (700+ KN range). Even the most advanced belt
constructions are designed to withstand ripping forces totaling only 1/10 the force
generated in actual service.
Due to the potentially tremendous destructive
forces involved, it becomes impossible to prevent a belt from
ripping.Therefore, in the early1970s, our engineers developedSensorGuard,
an electronic belt protection system that limits belt rip. Today, the Goodyear Engineered
Products Sensor Guard system stands alone as the most proven and reliable rip detection system in
the world, with installations on every continent except Antarctica. In coal, copper, iron ore and other applications,
Sensor Guard has proven itself by reducing downtime costs, replacement costs and lost production.
SENSOR GUARD ELECTRONIC BELT PROTECTION SYSTEM:
PROTECTING YOUR STEEL CORD INVESTMENT.
An industry innovation from the start.
The original Sensor Guard is a perfect example of the breakthrough engineering shared by many of our products.
Sensor Guard with RFID Technology works on the premise of closed-circuit sensor loops and RFID chips embedded in the
belt, monitored by electromagnetic detectors and an RFID Read Head, placed at high potential damage points.
As the conveyor belt moves, these loops and chips pass over the detectors and Read Head which record the loop and
RFID chip information. If the belt begins to rip, a sensor loop is also cut. As this cut loop passes over a detector, no pulse is
generated. The lack of pulse is recognized by the control unit, and Sensor Guard automatically signals the conveyor
control system to stop, to minimize further damage. Similarly, when excessive lateral belt movement occurs, failure of
a loop to pass over a detector within a prescribed distance or time will cause an automatic belt stop signal. The system
identifies exactly where the event occurs, based on the RFID chip information gathered.
This system combines the advantages of a processor and RFID chips, with the Sensor Guard system’s unparalleled
tradition of reliability, value and proven performance in the harshest of mining environments.
Ethernet capability allows to you to remotely monitor the system, to ensure proper settings and determine that the systems
are functioning as intended. All without having to leave your office.
Detector heads are

Distance between Detector
Loops varies depending on the
level of desired protection, i.e.,
100’ (30
m) loop intervals.
The detectors are hard-wired to the
control unit and transmit pulses every
time a loop is detected.
