Description

Bently 350042M 176449-02 Monitoring Module

Product Dimensions：

The Bently Nevada 3500/42M 176449-02 is a Proximitor/Seismic Monitor, a core component of the 3500 Series Machinery Protection System. It is designed to continuously monitor vibration and position by processing signals from various transducer types.

Product Detailed Description

The 3500/42M is a four-channel monitor that accepts input from proximity transducers, seismic sensors, or velocity sensors. The “M” designation stands for “Multimode,” indicating its enhanced signal processing capabilities compared to older models.

The specific part number 176449-02 refers to the Proximitor/Seismic Monitor module with Internal Terminations and Prox/Seismic I/O capabilities. It performs functions such as:

• Comparing monitored parameters against programmable alarm setpoints.

• Providing essential machinery health data to both operators and automated shutdown systems.

• Conditioning signals for vibration (radial, axial, casing) and eccentricity.

Technical Parameters

Product Advantages

• High Reliability: Designed for critical machinery protection, meeting API 670 standards for vibration monitoring.

• Versatility: A single module can be configured to monitor different types of vibration (e.g., shaft vibration or casing vibration) via software.

• On-board Diagnostics: The module continuously performs self-tests to ensure the integrity of the transducers and the monitor itself.

• Hot-Swappable: Can be replaced while the rack is powered, reducing system downtime.

• Buffered Outputs: Includes front-panel buffered outputs for easy connection to portable diagnostic equipment without interrupting the primary signal.

Important Considerations (Notes)

• Configuration: The module must be programmed using the 3500 Rack Configuration Software before operation. Incorrect configuration can lead to false alarms or failure to trip.

• I/O Compatibility: Ensure the I/O module (backplane) matches the 176449-02 front module. Mixing different types of I/O modules can damage the hardware.

• Barrier Requirements: If used in hazardous areas, appropriate Intrinsic Safety (IS) barriers or galvanic isolators must be installed between the sensor and the monitor.

• Grounding: Proper shielding and grounding of transducer cables are critical to prevent electromagnetic interference (EMI) from causing “noise” in the vibration data.

Product Applications

The 3500/42M is used across heavy industries where rotating machinery is critical to production:

1. Oil & Gas: Monitoring centrifugal compressors, pumps, and gas turbines.

2. Power Generation: Protection for steam turbines, generators, and cooling tower fans.

3. Mining & Metals: Monitoring large crushers, conveyor drives, and blowers.

4. Water Treatment: Large scale pumps and motors.
