BENTLY NEVADA 2300/20-00 Vibration Monitors

Overview

The Bently Nevada 2300/20-00 is a versatile vibration monitor designed for continuous monitoring and protection of less critical and spare machinery. It targets essential medium to low criticality machinery across industries like oil & gas, power generation, water treatment, pulp and paper, manufacturing, mining, and cement. This monitor continuously tracks vibration levels and provides high vibration alarms.
