Description

The Bently Nevada 3500/70M 136449-09 is a four-channel Reciprocating Impulse Velocity Monitor designed for critical machinery protection and diagnostics. This module is specifically engineered for reciprocating compressors to monitor impact events, rod-drop, and piston slap, providing early detection of mechanical degradation. As a core component of the Bently Nevada 3500 Series Machinery Protection System, the 136449-09 ensures reliable operation by identifying dynamic conditions that precede catastrophic failure.

Features

• Four independent monitoring channels for comprehensive multi-point coverage.
• Accepts inputs from velocity transducers and accelerometers to monitor reciprocating rod-drop and cylinder conditions.
• Configurable alarm and danger setpoints for automated machinery protection.
• Seamless integration with the 3500 rack system and System Processor for advanced diagnostics and data logging.
• Designed for high-reliability performance in demanding industrial environments.

Applications

This module is widely utilized in petrochemical, refining, and power generation facilities. It is essential for monitoring reciprocating compressors, pumps, and similar machinery where detecting mechanical impact and rod-drop is critical to preventing unplanned downtime.
