Bently Nevada 121M6469-02 – Ranger Pro Wireless Triaxial Vibration & Temperature Sensor
Overview
The Bently Nevada 121M6469-02 is a rugged wireless triaxial vibration and temperature sensor from the Ranger Pro series. It provides continuous monitoring of motors, pumps, compressors, gearboxes, and fans in industrial and hazardous environments.
This sensor measures acceleration, velocity, and casing temperature, supporting real-time waveforms, spectra, and PeakDemod analysis. With its ISA100.11a protocol, long battery life, and intrinsically safe design, it is ideal for predictive maintenance programs where wired connections are impractical.
