Executive Summary An iron ore miner currently employs a strategy of manual hand held data collection on shuttle pulleys and drives. This method necessitates production downtime to collect the data and exposes technicians to manual handling risks when accessing sensors through access hatches in the shuttle structure. Other current market wireless products were deemed very expensive and did not facilitate data collection in the required frequency ranges. In 2013 Good Vibrations Sensors Pty Ltd approached the Iron Ore Miner to trial the latest product in the range; the GV-700 Vibe-Port wireless bridge. The intention of the trial was provide the means through the wireless bridge to enable data collection while maintaining full production, whilst still utilising existing CSI 2130 vibration data analysers. Partial trials were conducted in 2013 with encouraging results, following realignment of aerials, trial data was successfully collected in April 2014. The GV-700 Vibe-Port wireless bridge trial data indicated accurate correlation with routine manually collected data. Both sets of data were collected simultaneously using two portable CSI 2130 vibration data analysers. This indicates that there is no loss of data quality or data collection speed when using the GV-700 Vibe-Port wireless bridge. Following the trial, the Iron Ore Miner (Asset Management) now recommends use of the GV-700 Vibe-Port wireless bridge to collect data, using existing vibration data analysers, where moving shuttle and inaccessible vibration and voltage regulated zones are inaccessible or where unsafe sensor data collection points to traditional remote sensors is no longer practical. Given the evidence and trial data received by our customer, Good Vibrations Sensors is happy to supply, support and service the GV-700 Vibe Port to any company facing the same restrictions.

Scope of Trial 1. Install the GV-700 Vibe-Port wireless bridge transmitter on the iron ore conveyor shuttle and connect the head

and tail pulley 100mv/g sensors to the transmitter. 2. Install the GV-700 Vibe-Port wireless bridge receiver on the external structure to enable remote data collection

by connecting the portable CSI2130 vibration data analyser to the receiver. 3. In a controlled environment collect simultaneous data through the GV-700 Vibe-Port wireless bridge and also

manually through remote sensors using a duplicate CSI2130 vibration data analyser. 4. Analyse and compare data collected from the GV-700 Vibe-Port wireless bridge and the manually connected

CSI2130 vibration data analyser.

Trial Results

• Data was collected simultaneously by two members of the sites Condition Monitoring Team • Data was comparable from both the GV-700 Vibe-Port wireless bridge and the CSI2130 vibration data analyser • An outer race defect present on one of the bearings was clearly picked up by both systems • The GV-700 Vibe-Port wireless bridge enhanced signal quality on some of the collected data • The condition monitoring team is confident that the GV-700 Vibe-Port wireless bridge fulfils the requirements

for safe collection of this vibration data during full production negating the need for production outages to collect the data.

Conclusion & Recommendations Made By Client

1. The GV-700 Vibe-Port wireless bridge eliminates the need to shut down the shuttle to collect vibration data 2. The GV-700 Vibe-Port wireless bridge does not lose any data quality when accessed by a CSI2130 vibration

data analyser 3. The GV-700 Vibe-Port wireless bridge does not add any significant data collection time to collect the routine

vibration data. 4. The GV-700 Vibe-Port wireless bridge fulfils the requirements to collect good repeatable data from moving

inaccessible assets requiring vibration or voltage regulated sensor data collection. The Iron Ore Miner recommended the use of this cost effective solution for wireless data collection on any equipment which cannot be safely accessed using traditional remote sensors.
