Ver todos los detalles

The Bently Nevada 3500/70M 176449-09 is a 4-channel Recip Impulse Velocity Monitor designed for the 3500 series rack-based monitoring system. It is specifically engineered to provide critical protection for reciprocating compressors by monitoring crankcase and crosshead vibration. The module processes inputs from seismic transducers, conditions the signals to derive precise vibration measurements, and evaluates them against user-programmable alarm setpoints.

Features

  • Four-channel monitoring capability for high-density rack configurations.
  • Supports multiple measurement modes including Impulse Acceleration, Acceleration 2, Recip Velocity, and Low Frequency Recip Velocity.
  • Programmable Alert and Danger setpoints for active static values.
  • Fast update rate of less than 100 milliseconds for real-time protection.
  • Compatible with 3500 series rack infrastructure and configuration software.

Applications

  • Reciprocating Compressors: Essential for detecting mechanical faults in crankcases and crossheads.
  • Pipeline Compression: Maintains the operational reliability of large-scale compressor stations.
  • Oil and Gas Production: Supports monitoring requirements for upstream and downstream gas compression assets.
  • Chemical and Petrochemical Processing: Provides vibration monitoring for critical rotating and reciprocating equipment.

Installation Guidelines

  • Ensure the 3500 rack power is disconnected before installing or removing the module.
  • The module should be seated firmly into the designated rack slot to ensure proper backplane connection.
  • Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).
  • Ensure proper grounding of the 3500 rack chassis to a common instrument ground to maintain signal integrity.
  • Verify that the module configuration matches the installed transducer type and required alarm setpoints via the 3500 configuration software.

FAQ

What is the primary function of the 3500/70M module?
The 3500/70M is a 4-channel monitor designed to process seismic transducer inputs for reciprocating compressor vibration analysis, specifically for crankcase and crosshead monitoring.

How does the 3500/70M differ from the 3500/72M?
While both are 4-channel rack-based monitors for reciprocating compressors, the 3500/70M is designed for seismic vibration inputs, whereas the 3500/72M is intended for piston rod position and drop monitoring using proximity probes.
