Product Description

Overview

The 177896-05 is a field-mountable Central Processing Module for the Bently Nevada ADAPT 3701/40 system, designed to deliver advanced machinery protection and real-time condition monitoring for rotating equipment. Optimized for turbines, compressors, pumps, and gearboxes, it processes high-speed dynamic signals close to the equipment, improving signal fidelity while reducing installation complexity.

Key Features and Advantages

High-Speed Signal Processing

• Equipped with a dedicated Digital Signal Processor (DSP) for real-time waveform analysis and vibration diagnostics.

• Performs synchronous and asynchronous sampling for accurate measurement of radial vibration, thrust position, casing vibration, and rotational speed.

• Compatible with a range of sensors including Proximitor probes, accelerometers, Velomitors, and seismic transducers.

Reliable Redundant Architecture

• Dual Ethernet ports support network redundancy for continuous data transmission.

• Integrated Modbus/TCP enables seamless communication with PLCs and DCS.

• Full integration with System 1 software for predictive maintenance and centralized analytics.

Rugged and Compact Design

• Designed for field mounting near equipment, reducing long sensor cables.

• Operates reliably in harsh conditions: -30°C to +65°C (-22°F to +149°F).

• Certified for hazardous areas: Class I, Div 2 and ATEX Zone 2.

Autonomous Protection Capabilities

• Contains internal logic and alarm management to act independently.

• Can trigger machinery trips and safety protocols without external controllers.

• Complies with API 670 guidelines for machinery protection in high-value assets.

Technical Specifications

Applications

• Machinery protection for turbines, compressors, pumps, and gearboxes

• Early detection of rotor imbalance, bearing wear, and gear damage

• Remote installation for reduced cabling in hazardous or space-constrained locations

• Integration with System 1 for predictive maintenance and analytics

FAQ

Q: Can the 177896-05 be used with 3500 series racks?
