Bently Nevada 3500/70 176449-09 Industrial Monitoring Module
Manufacturer: Bently Nevada
Product Number: 3500/70 (176449-09)
Category: Reciprocating Compressor Monitor Module (3500 System)
System Compatibility: Bently Nevada 3500 Machinery Protection System
Function: Provides advanced machinery protection and condition monitoring functions for reciprocating compressors
Product Description
The Bently Nevada 3500/70 (Part Number 176449-09) is a Reciprocating Compressor Monitor Module designed for use within the Bently Nevada 3500 Machinery Protection System.
It provides advanced machinery protection and condition monitoring functions for reciprocating compressors, focusing on parameters such as rod drop, frame velocity, crosshead acceleration, and impact monitoring.
This module is engineered to detect early-stage faults such as mechanical wear, looseness, valve failure, or misalignment. It processes dynamic signals from vibration and position sensors, applying configurable logic to issue Alert and Danger alarms for preventive maintenance and automatic shutdown protection.
The 3500/70 176449-09 complies with API 670 standards for machinery protection systems and integrates seamlessly with the 3500 rack system, enabling reliable communication with control and asset management platforms.
Key Features
-
Dedicated for reciprocating compressor condition monitoring.
-
Supports up to four input channels, each individually configurable.
-
Measures rod drop, frame velocity, crosshead acceleration, and impact.
-
Fully integrated with the Bently Nevada 3500 Rack System.
-
Two programmable alarm levels per channel (Alert and Danger).
-
4–20 mA outputs available via optional I/O modules.
-
LED indicators for module status: OK, TX/RX, and Bypass.
-
Configurable using 3500 Configuration Software.
-
High immunity to electrical noise, vibration, and temperature variation.
-
Compliant with API 670, CE, CSA, and ATEX standards.
