BluVib-M3

Overview

3-axis vibration

Measures X, Y and Z vibration with a programmable amplitude range up to ±16 g.

Wide bandwidth

DC to 6 kHz for trending, DC to 10 kHz for spectral analysis.

Long battery life

Field-replaceable battery, up to 5 years depending on measurement intervals.

ATEX option

Hazardous-area variant — II 1G Ex ia IIC T4 Ga; dust-certified option available.

Also measures temperature (−25 °C to +75 °C), captures up to 80 seconds at 25.6 kHz, mounts directly onto a machine, and is rugged and corrosion resistant.

Operating modes

Wakeup (recommended for best battery life)

The sensor powers on at a user-specified interval, broadcasts its presence, and the gateway connects and instructs it to take a measurement. While connected, the gateway can change the operating mode and any other parameters. The gateway then disconnects and the sensor returns to ultra-low-power sleep until the next interval.

Ready

Activated with the magnet, the sensor stays powered and keeps advertising (at reduced power after one minute), allowing repeated connections without re-waking it each time. Best for setup, demonstration and portable/tablet use — not recommended long term, as battery life is significantly reduced.

Event / Triggered

The sensor wakes at regular intervals but stays awake to monitor the input. If the signal crosses a programmed threshold, it captures the required post-trigger data and begins advertising so a client can connect and copy it, then returns to monitoring.

Logging

Operates unconnected, collecting and storing acceleration, velocity, temperature and battery data at a pre-set interval until woken with a magnet, then downloads to a ReST API or on a call for a specific date/time.
