Description

The Bently Nevada 3500/72M (176449-08) is a four-channel Reciprocating Rod Position Monitor designed for critical machinery protection in reciprocating compressor applications. It adheres to API 618 standards, providing continuous monitoring of rod position, rod drop, and hyper-compressor parameters. By processing signals from proximity transducers, the module provides both dynamic and static position measurements, comparing these values against user-programmable alarm setpoints to ensure asset integrity.

Features

Four-channel monitoring capability for high-density rack configurations.
Configurable for Rod Position, Rod Drop, and Hyper-Compressor measurement functions.
Provides machinery protection through continuous parameter monitoring and alarm setpoint comparison.
Includes front-panel buffered transducer outputs for connection to external diagnostic and analysis equipment.
Flexible I/O options including internal termination, external termination, or internal barrier configurations.

Applications

Reciprocating Compressors: Monitoring crosshead and rod behavior for wear, misalignment, and mechanical degradation.
Hyper-Compressors: High-pressure monitoring with specialized alarms for transducer loss.
Industrial Pumps: Tracking piston and plunger position to ensure smooth operation and early fault detection.
Rod Trajectory Analysis: Real-time tracking of lateral vibration and rod movement.

Installation Guidelines

The 3500/72M consists of a main module that plugs into the front of the 3500 rack and a corresponding I/O module installed at the rear.
The module can be placed in any of the 14 available monitor slots in the 3500 rack.
Ensure the system is powered down before inserting or removing any module to prevent electrical damage.
Use shielded cabling for all transducer inputs to minimize EMI interference in industrial environments.
Handle modules using ESD-safe practices to protect sensitive internal components.
Verify that the I/O module termination type (internal/external/barrier) matches your specific field wiring requirements.

FAQ

What is the primary purpose of the 3500/72M?

The 3500/72M provides machinery protection for reciprocating compressors and pumps by continuously monitoring rod position and comparing inputs against configured alert and danger setpoints.

What inputs does this monitor accept?

It accepts inputs from proximity transducers to measure rod position, rod drop, and hyper-compressor parameters.

Are the channels configurable?

Yes, the 3500 Rack Configuration software allows each channel to be configured in pairs to perform specific functions such as Rod Position, Rod Drop, or Hyper-Compressor measurements.
