301 In addition to alarm notifications, the software provides detailed operational data related to the sensors and the IntelliPlate™ system, enabling enhanced monitoring and diagnostics (i.e. battery life, connectivity of each sensor to the system, signal strength, etc.). 5. RESULTS FROM FIELD TESTING A series of tests were conducted at a mine site to validate the Intelliplate™ Sensor against the previously defined evaluation criteria. After installing four Intelliplate™ sensors in four filter plates, baseline testing confirmed that the sensors did not produce false positives, demonstrating reliable performance under normal filter press operation. After the base line testing, a 50mm incision was made on one filter cloth and a filter cycle was started. A few moments into the filtration step of the filter cycle, the Intelliplate™ sensor with the cut cloth, reported turbidity by activating the LED in the transmitter. At the same time, the HMI also reported turbidity. Figure 9 – LED Indicating failed filter cloth After the filter cycle and the subsequent opening of the filter, a check on the plate and cloth conducted. It was observed that the plate behind the cut cloth exhibited slurry residue across the entire pip surface of the filter plate. Slurry had passed through the cut in the cloth. In this test, the Intelliplate sensors and software displayed on the HMI functioned properly and provided an accurate result. Additionally, no other adjacent sensors triggered turbidity. A detailed evaluation of each system component confirms that the sensors are mechanically robust. No leaks were observed at the sensor installation points, and the sensors withstood the abrasive nature of the slurry passing over the probes without degradation.
