Key Highlights
- ✓ One cable installs — PoE powers the sensor and carries data on the same Ethernet run.
- ✓ High-fidelity data — DC through kHz bandwidth and ultra-low noise density for clean spectra.
- ✓ Raw or FFT — or both — time waveforms for root-cause analysis; spectra for continuous monitoring.
- ✓ NTP-timestamped — correlate data across sensors, machines, and test runs out of the box.
- ✓ Industrial-grade build — aluminium IP67 housing; M12 D-coded for secure, vibration-resistant connections.
- ✓ No lock-in — standard Ethernet transport and open-source tools for fast OEM and lab integration.

Product Overview
Industrial Triaxial Accelerometer with PoE Ethernet and M12 D-coded Connector
The A2E-TRI is an industrial triaxial accelerometer purpose-built for industrial vibration monitoring in permanent installations. As a PoE vibration sensor, it streams raw 3-axis acceleration data over standard 10/100 Ethernet, with Power over Ethernet (PoE IEEE 802.3af) supplying the sensor through the same M12 D-coded cable — eliminating separate power wiring and reducing installation complexity. Built-in NTP timestamping ensures samples are precisely time-aligned, making it straightforward to correlate data across multiple sensors, machines, and test runs.
Onboard FFT vibration analysis is computed per axis across all three channels, providing frequency spectra alongside raw waveforms — or instead of them. This edge vibration processing allows the condition monitoring sensor to be configured for continuous spectral monitoring with minimal data transfer, or switched to full raw capture when detailed time-domain data is needed for root-cause analysis. Both output modes can run simultaneously, making the A2E-TRI a versatile predictive maintenance sensor for any facility.
The entire data protocol is open source. All sensor communication uses published Protobuf schemas over standard TCP or UDP — no proprietary drivers, no vendor SDK, no licence fees. Pre-compiled bindings for Python, C, and C++ are included. Build your own toolchain or integrate directly into existing infrastructure.
An open-source browser-based interface application is also included. It provides live waveform display, FFT and PSD visualisation, sensor configuration, mDNS auto-discovery, and data logging to TSV or HDF5 files. Runs on any machine with Python 3.10+ and a modern browser. View on GitHub
Interface software — 512-bin FFT, 1 s sweep, 5 s burst capture showing raw data, FFT, and spectrogram views simultaneously.

Why the A2E-TRI
High‑Fidelity Vibration Over Standard Ethernet
Designed for engineers who need reliable, high-resolution vibration data in real installations — not just lab-bench prototypes.
- ✓ Deploy faster with one cable: PoE powers the sensor and carries data on the same Ethernet run — clean installs, less panel work, fewer failure points.
- ✓ Get high-fidelity vibration data — not just "overall levels": triaxial bandwidth designed for DC through the kHz range and ultra-low noise density for clean spectra and better baselining.
- ✓ Stream raw, compute FFT, or do both: capture time waveforms for root-cause analysis, or transmit spectra for continuous monitoring without moving huge datasets.
- ✓ Time-aligned datasets out of the box: built-in NTP timestamping enables correlation across sensors, machines, and test runs — especially valuable in multi-point monitoring.
- ✓ Designed for real installations: aluminium encapsulated, IP67-rated housing for industrial environments; M12 D-coded Ethernet for secure, vibration-resistant connections.
- ✓ Integrate without lock-in: standard Ethernet transport and open-source tools lower "time to first data" and simplify OEM and lab integration.
- ✓ Scale on existing IT/OT networks: 10/100 Ethernet fits common industrial switching topologies — no special gateway required.
- ✓ Reduce adoption risk: CE marked and tested; built for repeatable installs and documented integration.
Why Switch
Traditional Setup vs. A2E-TRI
Replace a multi-component vibration measurement chain with a single Ethernet vibration sensor.
| Traditional Setup | A2E-TRI |
|---|---|
| Sensor + DAQ + software | Single device |
| Complex wiring | Single PoE cable |
| Expensive system | Lower total cost |
| Offline analysis | Real-time FFT |
| Proprietary software | Open-source data protocol |
