Bently Nevada 140734-02

Product Overview

140734-02 High-performance, four-channel Proximitor vibration monitoring module launched by Bently Nevada, a subsidiary of Baker Hughes. As one of the core components of the 3500 condition monitoring and mechanical Protection system, the 3500/42M is specifically designed for comprehensive vibration, displacement and position monitoring of critical rotating and reciprocating machinery.

3500/42M adopts a single-width 1/4 slot design and can be directly inserted into a standard 3500 rack. The most prominent feature is its high degree of flexibility and multi-functionality Programmed through the accompanying 3500 Rack Configuration Software, each channel pair can be independently configured to perform any one of up to nine different measurement functions. Including radial vibration, axial displacement, differential expansion, eccentricity, REBAM, acceleration, velocity, absolute axial vibration and circular acceptance zone. This multi-functional in one machine design enables 140734-02 to adapt to a wide range of application scenarios, from simple pumps and fans to complex steam turbine generator sets and compressors. Making 3500/42M an ideal choice for comprehensive mechanical protection and condition monitoring.

Product functional features

Multi-functional and programmable channel pairs

The 140734-02's core innovation is that the four channels of the module are divided into two pairs. Each pair can be independently and simultaneously configured to perform different measurement tasks. For instance, channels 1&2 can be configured to monitor radial vibration, while Channels 3&4 can be simultaneously configured to monitor axial displacement. This design greatly enhances the utilization rate and application flexibility of individual modules.

The extensive measurement library supports 9 types of measurements, covering almost all key mechanical parameters of rotating machinery.

Displacement types include radial vibration, thrust position, differential expansion, and eccentricity.

The velocity category is divided into velocity and acceleration.

Advanced diagnostic REBAM, circular acceptance area.

Absolute shaft vibration of the compound type.

Rich static value output and precise alarm

Beyond simple RMS, for each measurement type, the 3500/42M module not only calculates a total RMS value but also outputs a series of Static Values. For example, in the radial vibration mode, 140734-02 will output Direct, Gap, 1X Amplitude, 1X Phase Lag, 2X Amplitude, Smax Amplitude, etc. These rich data provide key clues for in-depth fault diagnosis.

The two-level, programmable alarm system offers two levels of hardware relay alarms: Alert and Danger. The trigger threshold and time delay of the alarm can be precisely set through software, effectively preventing false tripping caused by instantaneous interference and ensuring timely action in truly dangerous working conditions.

Strong system integration and diagnostic capabilities

The 4-20mA standard output enables the main measurement values of each channel to be output to the DCS/PLC through the 4-20mA signal, achieving centralized monitoring.

The front panel buffer output provides high-quality raw sensor signals, facilitating on-site engineers to conduct detailed spectrum and waveform analysis using portable data collectors.

The three front panel leds of 140734-02 provide maintenance personnel with intuitive information on the health status, communication status and operation mode of the modules.

Applicable industry scope

3500/42M 140734-02 is applicable to all heavy industrial fields with complex and critical rotating equipment.

In the field of energy and power, we provide comprehensive monitoring for steam turbines, gas turbines and generators, including radial/axial vibration, thrust bearing wear, thermal expansion, large shaft bending and bearing health.

The condition monitoring of large centrifugal/axial flow compressors and reactor agitators in the petrochemical industry, especially the early fault warning of rolling bearings, is of vital importance.

Any key equipment in metallurgy, mining, papermaking, cement and other industries that requires high-precision and multi-functional monitoring of vibration and displacement.
