rEscan North America

By providing products and services that can detect problems in a conveyor system before becoming severe, rEscan can alert and inform on-site personnel and can help formulate an appropriate response to a problem - be it requiring repair, removal or further monitoring.  

This proactive maintenance can result in the conveyor system lasting well into the future and help minimize unscheduled down time and cost.  By utilising our remote and semi-remote systems this allows monitoring to occur at anytime without stopping the belt..

Steel Cord MFL Scanning

rEscan's technology is the answer to the early detection of cord breaks, corrosion and splice failure. 

The rEscan system works through magnetic flux leakage; steel cords are magnetized within the belting then measured for the amount of magnetic flux leakage seen in the belt. The key to this system is twin conditioning heads, which aligns all the magnetic domains thus giving a clean strong signal. The system is comprised of a set of two 'conditioning transducers (permanent magnets), one'sense transducer 'and one Tachometer. 

As the belt passes by the  transducer a signal is sent directly to a rEscan computer system then all data is reviewed on the belt in the Left, Center and Right orientation. Once the data has been analyzed, the rEscan Technician can accurately tell you where the damage is in your belt down to the closest millimeter in precision. "

Remote MFL Scanning

The rEscan Remote Conveyor Monitoring System is a permanently installed conveyor 
interrogation tool designed to look for internal cord damage / corrosion and internal
splice lay-up on steel cord conveyor systems via a phone line or LAN connection
without ever stopping production.

As operations push for extended production periods, maintenance windows continue
to shrink, Early detection, mapping and monitoring of damaged areas and splices allow
maintenance engineers to plan maintenance windows in advance and to extend the
service life of the conveyor systems.

The 'front-end' of the system comprises of a set of two 'conditioning transducers', one
'sense transducer' and one non-contact tachometer. As the belting passes the
conditioning transducers, a magnetic field is induced into the steel ropes within the
belting. Any breaks or corrosion produce small magnetic fields that induce voltages
within the sense transducer. These voltages are then passed back to the Main Computer
Housing. The tachometer is mounted to a nearby roller support and a small rare earth
magnet is attached to the roller itself. As the roller spins the magnet passes the
tachometer, inducing a voltage spike. These spikes are converted into square waves and
recorded. This signal is used to measure distances for plotting anomalies, sections and
entire belt length.

The main Computer Enclosure is housed in an IP67 Stainless Steel Enclosure; all on-belt
hardware is encased in the same material. The system is Windows XP Professional
based and uses the imbedded USB Bus for data collection. A VPN (Virtual Private
Network) connection is established via modem / LAN (via Ethernet, Fiber-Optics or Fire
wire) and the data is downloaded and a report is sent out.

The on-site computer has built-in security protocols to inhibit any form of tampering
and, should it lose power, it will automatically re-boot on restoration.

 
Semi-Remote MFL Scanning

Semi-Remote scanning entails permanently installing the sense and condition
heads along with the tachometer on your system; then a trained technician travels
onsite and personally extracts the data via laptop when a scan is needed.

With this option there is no downtime after initial installation. The data is collected with the
conveyor running. A full detailed report is then generated. The report will include
rEscan's recommendations in order of priority, a detailed belt map, lfe predictions (if required), splice condition and a table of anomalies within the belting.

 
Manual MFL Scanning

The full Manual scan entails a trained technician to travel on-site and perform a full longitudinal scan, condition inspection, cover profiles and life predictions of the conveyor belt.

After the inspection has been madea fully detailed report is generated and sent to the client. The report will include rEscan's recommendations in order of priority, detailed belt map, splice condition and a table of anomalies within the belt that are considered notable.

In the event that some of the anomalies need to be looked at closer, rEscan's portable X-Ray system can perform highly detailed digital images of these events.
