AutoStop BAMbino
AutoStop BAMbino
BAMbino is the world’s first portable Bearing Acoustic Monitor that provides accurate, easy, and early detection of faulty idler bearings. BAMbino is a handheld portable instrument that extracts bearing fault signatures measured from a distance of 0.1m to 3m away from the belt. A visual and audible alarm gives early notice of bearing damage, allowing forward planning of cost-effective maintenance.
Failure of conveyor systems is a significant problem in the mining industry, causing extended downtime, lost productivity, and increased risk of fire.
The most common cause of conveyor failure (and belt damage) is bearing seizure in the idlers supporting the belt.
Inspectors currently use subjective assessment, without scientific evidence, to detect faulty bearings. This highly unreliable and subjective method only detects bearings in the late stage of fragmentation, resulting in costly unscheduled maintenance.
Benefits:
- Fast and effective tool for predictive maintenance.
- Easy to use.
- Simple button operation via tactile membrane keypad with LCD display.
- Hand – held (230x95x50mm).
- Lightweight (less than 1kg).
- Screens out extraneous sources of noise, therefore usable in highly reverberant underground tunnels.
- Pre – programmable for up to 16 belt sections.
- Robust construction.
- Visual and audible alarm.
- User programmable.
- Threshold settings.
- Rechargeable battery.
- 12-month warranty.
