Bently Nevada 3500/42M Proximity Monitor

The Bently Nevada 3500/42M Proximity Monitor is a four-channel monitor that accepts input from proximity and seismic transducers, conditions the signal to provide various vibrations and position measurements, and compares the conditioned signals with user-programmable alarms.

The 3500 Rack Configuration Software performs the following functions:

• Radial vibration
• Thrust position
• Differential expansion
• Eccentricity
• REBAM
• Acceleration
• Velocity
• Shaft absolute

• Circular acceptance region

Features

• Four channel monitor
• Provide various vibrations and position measurements
• Input impedance 10kΩ standard I/O
• 7.7W power consumption
• Channels are programmed in pairs

General Introduction

Technical Specifications

• Power Consumption: It has a power consumption of 7.7 watts13.
• Input Signal Range: The input signal range is -10 VDC to +10 VDC3.
• Shaft Power Supply: The shaft power supply is -24 VDC3.
• Resolution: The resolution is 0.3662 A per bit3.
• Absolute Output Impedance: The absolute output impedance is 300 ohms.

Functional Features

• Diverse Measurements: With the 3500 rack configuration software, it can perform a variety of monitoring functions, including radial vibration, thrust position, differential expansion, eccentricity, acceleration, velocity, shaft absolute, and circular acceptance region16.
• Channel Pair Programming: The monitor channels are programmed in pairs. For example, channels 1 and 2 can perform one function, while channels 3 and 4 can perform another or the same function6.
• Alarm Function: It continuously compares the monitored parameters against configured alarm setpoints. When the monitored values exceed the set alarm thresholds, it can promptly trigger alarms to notify operation and maintenance personnel36.
• Data Logging: It is capable of recording and storing monitoring data, which is convenient for users to conduct historical data analysis and trend research, facilitating the diagnosis of potential faults23.
