Bently Nevada 121M6469 – Ranger Pro Wireless Triaxial Vibration & Temperature Sensor
Overview
The Bently Nevada 121M6469 is a wireless triaxial vibration and temperature sensor built for the Ranger Pro series. It delivers continuous monitoring of rotating machinery by capturing vibration across three axes (X, Y, Z) and providing temperature data.
