Bently Nevada 130739-01 Dual Velocity Monitor Module

Product Overview

The Bently Nevada 130739-01 Dual Velocity Monitor Module delivers accurate vibration velocity monitoring for critical rotating machinery protection.
Designed for the proven 3300/55 system, this module supports reliable condition monitoring in demanding industrial environments.
Moreover, its dual-channel architecture enables simultaneous measurement of two independent velocity inputs with consistent accuracy.
Therefore, maintenance teams gain earlier insight into mechanical degradation before failures escalate into unplanned downtime.
In addition, the module reflects Bently Nevada’s long-standing expertise in machinery protection and vibration diagnostics.

Key Features and Functional Benefits

The dual-channel design allows continuous monitoring of two vibration points within a single compact module.
Moreover, the 100 mV per inch per second scale factor ensures high sensitivity for detecting subtle vibration changes.
The standardized 4 to 20 mA output simplifies integration with control systems and plant monitoring platforms.
Therefore, operators can trend vibration velocity data using existing PLC, DCS, or SCADA infrastructures.
In addition, the robust electronic design supports stable performance in harsh temperature and industrial conditions.
