Low and high, both critical.
Tooth-level signatures live in two extreme bands at once — sub-10 Hz mechanical drift and ultrasonic harmonics. Standard accelerometers drown one to chase the other.
Use case
Latest releaseGearbox
Read every tooth, at 600 RPM.
In a worm-gear reducer where accelerometers drown the <10 Hz mechanical signatures, Dragonfly® reads tooth-level vibration in real time — in a footprint small enough to fit where conventional sensors can't.
Challenge
Gear health monitoring breaks every conventional sensor.
Monitoring gear health requires capturing both low- and high-frequency mechanical signatures with high precision — something current sensing solutions fail to achieve. And integration is no easier: the gearbox is a compact assembly with extremely limited available space, leaving no room to embed conventional sensors without compromise.
No room left for a probe.
Gearboxes are dense, sealed, and built to spec. Conventional sensing solutions don't fit where the signal is — they get pushed to the housing, far from the source.
Performance or integration. Never both.
Every current sensor forces a trade-off: smaller means less sensitive; more sensitive means too bulky to embed. The signal you actually need is on the wrong side of that line.

Paul walks through a real worm-gear reducer measurement — what Dragonfly® picks up at the tooth-mesh that a housing accelerometer smears into noise.
The shift
Same gearbox. Completely different story.
Before
Global vibration, noisy signal.
A conventional accelerometer mounted on the housing smears the tooth-mesh harmonics into structural noise. The early defect window is invisible — by the time the alarm fires, the gear is already pitted.
Now
Tooth-level insight, clean signal.
Dragonfly® resolves each tooth-mesh harmonic and its sidebands cleanly, in real time, in a footprint small enough to sit where the signal is born. Early defects become visible weeks before failure.
Found in
Where gearboxes show up.
The same gearbox shows up across radically different industries — and the vibration challenge follows it everywhere. Here's where we deploy Dragonfly® on it.
Energy
Wind turbine main gearboxes and hydro reducers — high-torque, low-RPM, catastrophic if they fail unannounced.
Industry 4.0
Conveyor drives, press reducers, factory automation — the backbone of every production line.
Aerospace
Helicopter main gearboxes and propulsion reducers — qualification, fleet health, no second chances.
Maritime
Ship reduction gearboxes and propeller shafts — sealed environments, costly interventions, long missions.
Mining
Crusher and mill drives, conveyor reducers — heavy shocks, abrasive load, downtime is daily revenue lost.
FAQ
Common questions.
Yes. IP67-rated for waterproof and dust resistance, M12 industrial connector, validated thermal range. Designed to live on or inside operating gearboxes — including outdoor wind-turbine nacelles, mining drives and maritime engine rooms.
It mounts on the housing — no penetration of the seal required. The thin piezo cell + edge electronics capture tooth-mesh signatures through the housing wall, so you don't compromise the gearbox warranty or its lubrication seal.
Up to 1000× more sensitive across both low- and high-frequency bands, with a 1 Hz–1 MHz bandwidth that resolves tooth-mesh harmonics and their sidebands cleanly. A standard accelerometer smears those signatures into structural noise — the BEFORE/NOW comparison above is the visual proof.
36 g, M12 connector, 4 mA (< 100 mW) power draw. One sensor per gearbox is typically enough to surface every meaningful defect signature. No bracket, no custom mount.
Both. Dragonfly® IO streams the full spectrum to the edge in real time, with on-device anomaly detection that only forwards what matters to your cloud or dashboard — so you don't drown your operators in raw data.
