A belt walk sends someone along a noisy conveyor to listen for faults. It catches only late-stage damage, and misses the rollers that fail between walks. Senstrali Triage listens continuously, grades each zone against its own baseline, and gives your team more confidence in a stop-or-run call.
Somebody walks beside a running conveyor, in hearing protection, trying to hear a bad roller.
By the time a roller is audible from the walkway, most of its life is gone.
A roller that starts to go the day after a walk runs unwatched until the next one.
Sensor nodes clamp to the stringer and listen for structure-borne ultrasonics and vibration. One cable carries power and data to a controller at the end of the section. The controller keeps the raw recordings and sends the numbers to your server.
Four measurements per node: ultrasonic, vibration, audio and temperature. Steel-to-steel coupling through a magnetic clamp; no drilling, no change to the roller or the frame. Designed to meet IP67.
One per conveyor section. Powers the nodes, runs the measurements, stores every waveform locally and sends results over LTE-M. No connection to site IT or OT.
A server in Australia for your site alone, or a machine on your premises. Triage list, trends, alerts by SMS and email, and playback of any recording.
A zone is the few frames either side of a node. Each zone is graded against its own baseline, so a section that has always been noisy is not flagged for being noisy, only for changing. Rate of change counts as much as level.
Within its own baseline.
Moving away from baseline. Worth a look on the next walk, and worth watching between walks.
Well outside baseline, or changing quickly. Your team gets the trend and the recording; the decision stays with them.
Node offline, faulted or still baselining. Never shown as Healthy.
24/7 monitoring of every zone on the section, not a walk every few weeks. Rollers that would have failed between walks are seen changing.
Independent of site IT and OT. Own power, own link, own server. No change to the asset, no software on your network.
Install on a short section to start, then chain sections together. Nodes are added along the same cable.
We would rather you knew before a pilot than found out during one.
About three months. We monitor and report; the pilot is scored against KPIs agreed with you at scoping, in your numbers. Founding pilots are under way in Western Australia; places for the next round are limited.
Senstrali was founded by Jason Milne, PhD, after twenty years designing sensors and instruments for extreme environments, including thirteen years at SLB on downhole ultrasonic and pressure measurement. About Senstrali.
The same hardware is being applied to other rotating equipment, and we take on sensing and instrumentation problems where off-the-shelf parts will not survive. Get in touch.
