Rapid zero-cabling deployment for Balance of Plant assets: monitoring radial, axial, and tangential vibration with 5-year battery life and long-range LoRaWAN telemetry.
Captures low-to-mid frequency mechanical degradations such as shaft misalignment (2X), mass unbalance (1X), and structural looseness across all three spatial planes simultaneously, preventing secondary damage to seals and couplings.
Features an ultra-low power capacitive micro-electro-mechanical system (MEMS) accelerometer etched on silicon. Microscopic suspended silicon proof masses deflect under acceleration, altering the capacitance between stationary fingers. An on-chip ASIC converts capacitance delta into calibrated 16-bit digital acceleration for X, Y, and Z axes simultaneously before passing through an internal wake-on-motion low-power supervisor.

The wireless sensor uploads periodic dynamic bursts over sovereign LoRaWAN. The Optruss Edge Engine evaluates overall ISO 10816-3 RMS velocity velocity against asset class limits. If abnormal trending is detected, the gateway automatically commands the sensor via downlink to switch from standard 4-hour interval to high-frequency 5-minute continuous burst mode for high-resolution tracking.
The core sensing workhorse for rotating machinery: capturing bearing race spalling, gear mesh harmonics, and mechanical unbalance up to 12 kHz.
The gold standard for fluid-film hydrodynamic bearings: measuring absolute shaft dynamic displacement, radial vibration, axial thrust position, and phase reference up to 10 kHz.
The earliest warning system on the P-F curve: detecting sub-micron lubrication film degradation, microscopic metal-to-metal contact, and pressurized gas leaks at 38 kHz.
Zero-downtime non-intrusive electrical monitoring from the MCC: diagnosing motor broken rotor bars, stator turn faults, and mechanical eccentricity via high-resolution current demodulation.
Continuous non-contact optical temperature telemetry: monitoring bearing housing caps, rotating kiln shells, electrical busbars, and furnace refractories up to 600°C.
Deterministic high-speed acquisition and local AI inference: running air-gapped on DIN rails with FPGA DSP, dual isolated Ethernet, and sovereign Merkle audit ledger.
Benefit from sub-millisecond edge FFT processing, early P-F curve anomaly detection, and automated CMMS work order generation.
