Built like the axle it sits on.
A solid block of machined aluminium, potted through, with no cable, connector or charging port to fail. It sits flush on the transmission, transfer gearbox, differentials and suspension, takes the rock strike and the pressure washer, and keeps working from −40 °C mornings to a 90 °C housing. It captures vibration when the truck is in a comparable operating window, computes the diagnostic features on board, and reports to the hub in the cab by radio. Built to outlast the component it watches.
What you get
- Wideband triaxial vibration to 10 kHz, so early bearing and gear faults are in range
- Magnetometer shaft-speed reference for order tracking under changing speed and load
- Features computed on the sensor; kilobytes leave it, not megabytes
- Primary lithium cells, field replaceable, multi-year life, no charging
- Machined from a single aluminium billet and potted solid: sealed to IP67, shock and vibration qualified, −40 °C to +85 °C
- No cable, no connector, no charging port: the three things that fail first on field electronics are not there
- Sits flush on a machined pad, bolted or bonded to the housing; nothing to catch, nothing protrudes
Built to last
- Solid aluminium, one joint
- The housing is machined from a single aluminium billet. The only joint is under the cap, and it carries an O-ring. Nothing else on the outside can open, crack or leak.
- Potted solid
- Inside, every component is encased in potting compound. There is no air space, nothing to shake loose, and nothing for water to reach even if it got past the seal. It is a solid block that happens to think.
- No cable, no connector, no charging port
- The three things that fail first on field electronics are simply not there. Power is a sealed cell inside the housing and data leaves by radio through the cap.
- Takes the rock strike and the pressure washer
- Sealed to IP67 and qualified against the shock and random-vibration profiles written for equipment bolted to off-highway vehicles. Wash the truck; leave the sensors on.
- −40 °C to +85 °C, no heater
- Primary lithium cells keep their capacity through a northern winter and never need charging, which is how every rechargeable field device dies in the cold.
- Low, flush, out of harm's way
- 45 mm across and 28 mm tall, sitting flat on its pad with nothing to catch. If the housing it is bolted to survives the shift, so does the sensor.
Specification
| Vibration | Triaxial wideband accelerometer, DC to 10 kHz, ±50 g, on a rigid base pedestal. Low-rate six-axis IMU for orientation and regime context. |
|---|---|
| Shaft-speed reference | Three-axis magnetometer reading flux leakage from the rotating shaft. Gives the order-tracking reference without touching the shaft. |
| Temperature | Component surface through the mount, plus housing temperature, both trended against load. |
| Processing | Nordic nRF52840, Arm Cortex-M4F with FPU. Order tracking, envelope spectrum and diagnostic features computed on the sensor. |
| Radio | Bluetooth LE 5 to the Firefly hub. Features every capture; raw waveform bursts on request. |
| Capture | Regime-triggered bursts. The sensor sleeps until the hub signals a comparable operating window, then records a few seconds at full rate. |
| Power | Primary lithium (LiSOCl₂) cells, field replaceable, no charging. Multi-year service life at the standard capture schedule. |
| Housing | Machined from a single aluminium billet; every component encased in potting compound; one O-ring joint under an impact-resistant, RF-transparent cap. No cable, connector or charging port anywhere on the outside. Sealed to IP67 and built for pressure washing. |
| Environment | −40 °C to +85 °C operating, no battery heater needed. Qualified against the random-vibration and shock profiles written for equipment mounted on off-highway vehicles. Rock strike, mud, salt and hydraulic oil are the normal case, not the exception. |
| Mounting | Flush on a machined mounting pad that is bolted or bonded to the component housing. The sensor threads into the pad from below, so nothing protrudes. Magnetic base for survey use only. |
| Size and mass | Ø 45 mm × 28 mm including cap. 120 g. |
