Brief Introduction

3500/42-04-01

The main functions of Bently 3500/42M displacement/velocity and acceleration monitor are: to provide 1) continuous comparison of the current mechanical vibration and configuration alarm set points to drive the alarm to protect the machinery, 2) to provide basic mechanical vibration information to the operation personnel and maintenance personnel. The alarm set points are configured by means of the 3500 frame configuration software. Alarm setpoints can be configured for each valid proportional value, while only two of all valid proportional values can be configured for dangerous setpoints. When issued from the manufacturing plant, the 3500/42 is not configured. When required, the 3500/42M can be installed in the 3500 frame and configured to perform the required monitoring functions. This allows you to store a single monitor for use in a variety of different applications. The 3500/42 monitor is a quad-channel monitor that receives an input from an eddy-current displacement sensor and a proximitor and seismic transducer and drives an alarm based on this input. The 3500/42 can be programmed with the 3500 frame configuration software to perform the following measurement functions: radial vibration, axial position, eccentricity, differential expansion, acceleration, velocity. The module can receive input from a variety of sensors, including the following Bently Nevada sensors:Bently 3500/42-AXX-BXXI/O module type01 Displacement/Velocity Acceleration I/O Module with Internal Terminals02 Displacement/velocity acceleration I/O module with external terminals03 Triple redundant (TMR) I/O module with external terminals04 I/O module with internal barrier (4 × displacement/acceleration channels) and internal terminals05 I/O module with internal barrier (2× displacement/acceleration + 2× speedometer channels) and internal terminals06 I/O module with internal barrier (4 × speedometer channels) and internal terminals07 Shaft absolute vibration I/O module with internal terminals08 Shaft absolute vibration I/O module with external terminals09 Displacement/velocity meter I/O module with internal terminals10 Displacement/velocity meter I/O module with external terminals
