GE / Bently Nevada 3300/15-03-01-02-00-00-00 Dual Vibration Monitor

The GE / Bently Nevada 3300/15-03-01-02-00-00-00 is a dual-channel vibration monitor for continuous online machinery health surveillance. It accepts inputs from two proximity probe transducer systems to measure radial vibration independently across each channel. Engineered to API standards, this microprocessor-based monitor delivers peak-to-peak amplitude detection with digitally adjustable Alert and Danger thresholds per channel, supporting early failure detection and proactive maintenance strategies across rotating and reciprocating machinery applications.
