Bently Nevada 3500/72 176449-08+135489-01 Industrial Monitoring Module
Manufacturer: Bently Nevada
Product Number: 3500/72 (176449-08 + 135489-01)
Category: Reciprocating Compressor Impact / Velocity Monitor Module
Series: Bently Nevada 3500 Machinery Protection System
Application: Continuous machinery protection and condition monitoring for reciprocating compressors
Product Description
The Bently Nevada 3500/72 (176449-08 + 135489-01) is a Reciprocating Compressor Impact / Velocity Monitor Module designed for use in the Bently Nevada 3500 Machinery Protection System.
It provides continuous machinery protection and condition monitoring functions, specifically for reciprocating compressors, where it measures impact, frame velocity, and acceleration to detect early signs of mechanical degradation.
This module helps identify issues such as looseness, valve failure, piston slap, and structural vibration. By providing two levels of alarms (Alert and Danger), it enables predictive maintenance and automatic shutdown protection in compliance with API 670 standards.
The 3500/72 system consists of the monitor module (176449-08) and the associated I/O module (135489-01), working together to provide real-time monitoring and signal processing.
Key Features
-
Monitors up to four independent channels for velocity and impact.
-
Designed specifically for reciprocating compressor monitoring.
-
Detects mechanical looseness, impact events, and frame vibration.
-
Provides two alarm levels per channel (Alert and Danger).
-
Integrates seamlessly into the Bently Nevada 3500 System.
-
Optional 4–20 mA outputs via I/O module.
-
Front-panel LED indicators for system status (OK, TX/RX, Bypass).
-
Configurable via Bently Nevada 3500 Configuration Software.
-
Compliant with API 670, CE, CSA, and ATEX standards.
-
Robust, industrial-grade design suitable for continuous operation.
