What we measure
In the oil, viscosity, water and moisture, oil ageing, particle contamination (ISO 4406 code) and the wear-metal trend are measured. On the machine, vibration level and temperature are monitored. When a reading moves away from the machine's normal range, the screen changes from green to amber or red. Warning signs and what they mean
What we do not measure: metal identification (which metal a particle is), acid and base number (TAN/TBN) and vibration spectrum analysis (FFT). These tests need a laboratory and a specialist. DataMonitor does not replace them. It works alongside them. The system watches for warning signs and gives early warning. It does not diagnose faults.
Mining FAQ
How is oil contamination monitored in a dusty mine?
Dust and water get into conveyor drive and crusher gearboxes. They raise the particle counts and the water content in the oil. An online particle counter can show the change early as an ISO 4406 code. The oil sensor also tracks water and ageing. Checking the filter and entry points when the code rises reduces the risk of dirty-oil breakdowns.
Can oil be measured at a remote site without shipping samples?
Yes. Fixed sensors measure the oil on site. They show the results on the monitoring screen next to the machine, and no internet is needed. To follow it from head office, you can use Level 3 online access. It sends alerts to your phone and email, but it needs an internet connection at the site.
What warning signs are monitored on a crusher gearbox?
In the oil we track particle contamination (ISO 4406 code), water, viscosity change and the wear-metal particle trend. These can show dust getting in, sealing problems and gear or bearing wear early. We also measure vibration level and temperature on the bearing housing. These signs are an early warning to help you plan the repair. They are not a definitive diagnosis.
