Bently Nevada 3500/70M Recip Impulse Velocity Monitor

The Bently Nevada 3500/70M Recip Impulse Velocity Monitor is a 4-channel device used as part of the reciprocating compressor solutions package to monitor compressor crankcase and crosshead vibration. The monitor accepts input from seismic transducers, conditions the signal to derive vibration measurements, and compares the conditioned signals with user-programmable alarms.

You can program each channel using the 3500 Rack Configuration Software to perform the following functions:

• Impulse acceleration
• Acceleration 2
• Recip velocity
• Low frequency recip velocity

Features

• Accepts from 1 to 4 inputs including:
• Velocity
• Acceleration transducer signals
• Rack space requirements:
• Monitor: 1 full-height front slot
• I/O Modules 1 full-height rear slot
• Programmable alarm delays
• Measured variables:
• Impulse acceleration
• Acceleration 2
• Recip velocity

• Low frequency recip velocity

General Introduction

Technical Features

• Input Capability125：It can accept inputs from 1 to 4 seismic transducers, including velocity and acceleration transducer signals. This wide range of input options allows it to adapt to different sensor configurations and measurement requirements.
• Measurement Functions124：Using the 3500 rack configuration software, each channel can be programmed to perform functions such as impulse acceleration, acceleration 2, recip velocity, and low frequency recip velocity measurement. This provides comprehensive information about the compressor's vibration and movement characteristics.
• Alarm Function5：The monitor allows for user-programmable alarms. It compares the measured vibration data with the set alarm thresholds and triggers alarms when the values exceed the setpoints, enabling timely detection of potential problems.
• Rack Space Requirements12：It requires 1 full-height front slot for the monitor and 1 full-height rear slot for I/O modules, which ensures efficient integration into the 3500 monitoring system.

Applications

• Oil and Gas Industry：In oil and gas production facilities, reciprocating compressors are widely used to transport and compress gases. The 3500/70M plays a crucial role in monitoring the vibration of these compressors, helping to prevent equipment failures and ensure the smooth operation of the production process.
• Chemical Industry：In chemical plants, reciprocating compressors are used in various chemical reaction and material transportation processes. The 3500/70M helps to monitor the condition of these compressors, ensuring their stable operation and preventing potential safety hazards.
• Power Generation Industry：In some power generation systems, reciprocating compressors are used for specific gas compression tasks. The 3500/70M provides real-time vibration monitoring, contributing to the reliable operation of the power generation equipment.
