Amphenol Wilcoxon 883M Digital Triaxial MEMS Accelerometer
Amphenol Wilcoxon 883M Digital Triaxial MEMS Accelerometer is a high-precision sensor designed for industrial vibration monitoring. The Amphenol Wilcoxon 883M features a triaxial accelerometer and temperature sensor, capable of measuring acceleration of up to ±16g-peak. The sensor outputs vibration spectrum, time waveforms, and 15 calculated vibration metrics for each axis, providing comprehensive data for condition-based maintenance and fault diagnostics. With a frequency response range of 2Hz to 5kHz, the 883M ensures detailed vibration analysis. The device utilizes the Modbus RTU communication protocol for stable data transmission and is compatible with programmable logic controllers (PLCs), distributed control systems (DCSs), supervisory control and data acquisition (SCADAs), and HMI displays.
The sensor is designed for harsh environments, featuring an IP67 rating and an operating temperature range of -20°C to +70°C. The 883M is ideal for monitoring rotating machinery, transmission systems, manufacturing equipment, HVAC systems, and more.
