Wilcoxon 883M Digital Triaxial MEMS Accelerometer

Compact digital vibration sensor for machine health monitoring — synchronous three-axis MEMS acceleration plus temperature, Modbus RTU output of spectra, time waveforms, and 15 calculated vibration metrics per axis, in an IP67 side-exit M8 package.

Key advantages

Triaxial + temperature — Synchronous X/Y/Z vibration and temperature (−20…+70 °C sensing).
Digital metrics — Modbus RTU (RS-485) outputs spectrum (0–5 kHz, 6145 lines), 1 s time wave, and 15 calculated metrics per axis.
±16 g / 2 Hz–5 kHz — 0.488 mg resolution; resonance about 6.9 kHz; bands align with ISO 10816-3 / 20816-3 guidance.
IP67 compact body — About 35 mm dia. × 26 mm; 75 g; A6061 aluminum upper / 303 SS lower; side-exit 4-socket M8.
Mount options — Adhesive flat base standard; optional screw or magnet adapters; kit SKUs with 50 ft mating cable.

Typical applications

Rotating machinery: motors, fans, blowers, pumps, compressors.
Transmission systems: gearboxes, couplings, bearings.
Manufacturing equipment: CNC machines, conveyor belts.
HVAC assets: compressors, cooling towers, cranes, lifting equipment.

Selection guide

Kit — 883M base vs 883M-SMA / -MMA / -FMA kits (adapters + RM8-ST-J94-50 cable).
Mounting — Adhesive vs screw adapter vs magnet adapter for the measurement point.
Network — RS-485 Modbus RTU baud (OEM recommends 9,600 or 115,200; max 921,600).
Power — 6–24 VDC supply planning.

Common mistakes

Assuming hazardous-area approvals — OEM lists hazardous area approvals as N/A.
Treating it as a 4–20 mA IEPE sensor — output is Modbus RTU digital, not analog IEPE.
Ignoring cable/shield practice on RS-485 runs — OEM recommends shielded 4-conductor PVC jacket cable.
