Product Overview

The Bently Nevada 86739-01 (3500/16) provides high-integrity vibration monitoring for critical rotating assets within the 3500 Machinery Protection System. This dual-channel module processes signals from two independent vibration transducers, allowing operators to monitor turbines, compressors, and pumps in real-time. It translates raw sensor data into actionable machine health information, triggering alarms or shutdowns when vibration levels exceed safe thresholds. We provide this module as 100% Brand New and Original, ensuring your protection system operates with factory-certified precision.

Technical Specifications

The 86739-01 utilizes high-speed processing to handle independent alarm logic for two separate machinery points.

Engineering Advantages

• Redundant Machinery Safeguarding: The 3500/16 architecture allows for independent channel configuration. This ensures that a fault on one bearing or shaft location does not compromise the monitoring of the second channel, providing a robust layer of safety for high-value equipment.

• Programmable Protection Logic: Engineers configure the 86739-01 with specific "Alert" and "Danger" setpoints. The module executes these trip commands via programmable relays, providing near-instantaneous machine shutdown capability to prevent catastrophic mechanical failure.

• Seamless Rack Integration: The module slides directly into any standard 3500 rack slot. It communicates via the backplane to the Rack Interface Module (RIM), allowing for plant-wide data distribution and remote diagnostic access through System 1 software.

• Industrial Noise Immunity: Advanced filtering circuitry within the module rejects electromagnetic interference (EMI) and radio frequency interference (RFI). This ensures the monitor only reacts to actual mechanical vibration, preventing "false trips" in noisy industrial environments.

FAQs

• Can I use the 86739-01 as a standalone vibration monitor?

  No. The 86739-01 requires a Bently Nevada 3500 rack and power supply to function. It operates as part of a distributed machinery protection system and relies on the rack backplane for power and communication.

• Does this module support different types of vibration sensors?

  The 3500/16 series typically interfaces with Proximitor sensors, accelerometers, and velocity transducers. However, you must configure the module software to match the specific scale factor and input type of your installed sensors.

• Is the 86739-01 hot-swappable?

  Yes. You can replace the module while the rack is powered, provided you follow proper safety procedures. The 3500 system maintains protection on other modules during the swap.

• What is the condition of this unit?

  We guarantee this 86739-01 is 100% Brand New and ships in its original Bently Nevada factory packaging. It includes our standard 12-month warranty.
