Bently Nevada 3500/40M Proximity Monitor

The Bently Nevada 3500/40M Proximity Monitor s a 4-channel monitor that accepts input from Bently Nevada proximity transducers, conditions the signal to provide various vibration and position measurements, and compares the conditioned signals with user-programmable alarms. The user can program each channel of the 3500/40M with the 3500 Rack Configuration Software to perform any of the following functions:

• Radial vibration
• Thrust position
• Differential expansion
• Eccentricity
• REBAM

Features

• 1 to 4 proximity transducer signals
• Front panel LEDs: OK, TX/RX, Bypass
• User-programmable alarms
• 7 watt power consumption
• Total input impedance:
• Standard I/O 10 kΩ
• Accuracy:
• Direct/gap/1X/2X: ±0.33% of F.S.
• Smax: ±5% maximum

General Introduction

Technical Specifications3

• Power Consumption: It typically consumes 7.7 watts.
• Input Impedance: The standard I/O is 10 kΩ.
• Accuracy: Direct/gap/1x/2x is ±0.33% of F.S., and S max is ±5% maximum.
• Output Impedance: The output impedance is 550 Ω.
• Sensitivity: For radial vibration and thrust, it can be 3.94 mV/µm or 7.87 mV/µm.

Functional Features

• Versatile Measurements236: It can perform various monitoring functions like radial vibration, thrust position, differential expansion, eccentricity and REBAM analysis through the 3500 rack configuration software.
• Programmable Alarms: Users are enabled to configure alert and danger setpoints for different parameters35. The monitor continuously compares the monitored values with the set alarm thresholds and promptly triggers alarms when anomalies are detected235.
• Status Indicators2: The front panel is equipped with LEDs, including OK, TX/RX, and bypass LEDs, which visually indicate the operating status of the module.
• Output Options46: It usually offers multiple output options such as analog output, relay output, and digital communication output, enabling seamless connection with various control and monitoring systems.
