Product Description
The Bently Nevada 3500/16 (86739-01) is a dual-channel vibration monitor designed for the 3500 Machinery Protection System. It provides continuous, real-time vibration monitoring for critical rotating equipment such as turbines, compressors, and pumps.
This module interfaces with Proximitor probes, velocity sensors, or accelerometers to capture radial vibration, axial thrust, and casing vibration data. The dual-channel design allows independent monitoring of two points or a single redundant pair, with user-defined Alert and Danger setpoints for immediate protective action.
As part of the 3500 rack, the 86739-01 ensures machinery safety by processing transducer signals, providing alarm outputs, and enabling buffered data access for diagnostics and predictive maintenance.

Frequently Asked Questions
Does the 86739-01 include the I/O module?
No, the 86739-01 is the front-mounted monitor. A rear-mounted I/O module (e.g., 125715-01) is required for field wiring.
Can I use this for Thrust (Axial) position?
It is optimized for vibration monitoring. For dedicated Proximity/Thrust measurement, the 3500/40M or 3500/42M modules are recommended.
