4-CH Machinery Protection Card | New Bently Nevada 3500/42

Product Details

Product Overview

The Bently Nevada 3500/42-01-00 functions as a high-precision, four-channel Proximitor and Seismic Monitor within the 3500 Series Machinery Protection System. This module acquires signals from a diverse range of transducers—including proximity probes, velocity sensors, and accelerometers—to provide continuous monitoring of radial vibration, shaft position, and casing velocity. By processing raw sensor data into actionable machinery health metrics, the 3500/42-01-00 enables early detection of mechanical imbalances, misalignment, and bearing wear, ensuring the safety of critical rotating assets.

Part Number Breakdown: 3500/42-AA-BB

• 3500/42: Proximitor/Seismic Monitor Module.

• 01 (AA): I/O Module Type (Prox/Seismic I/O Module with Internal Terminations).

• 00 (BB): Agency Approval Option (None).

Technical Specifications

Engineering Advantages

• Multi-Transducer Versatility: The 3500/42-01-00 supports a wide array of sensors, allowing engineers to monitor different machine types (e.g., fluid-film bearing turbines or rolling-element bearing pumps) using the same hardware platform.

• Advanced Signal Filtering: Integrated programmable filters isolate specific frequency bands. This allows the module to reject unrelated mechanical noise and focus exclusively on critical fault frequencies, such as 1X or 2X vibration components.

• Continuous Self-Diagnostics: The module identifies transducer faults, cable breaks, and internal hardware failures in real-time. It activates "Not OK" status indicators immediately to prevent false trips and alert maintenance teams to instrument issues.

• Millisecond Alarm Logic: Independent hardware logic on the module executes "Alert" and "Danger" setpoint comparisons. This local processing ensures that the machinery protection system initiates shutdown sequences within milliseconds of a violation, regardless of network traffic.

• Buffered Output Access: Front-panel buffered outputs provide direct access to the raw analog signals. This enables vibration technicians to connect portable diagnostic equipment (like the Scout or ADRE systems) without disturbing the permanent protection wiring.

FAQs

Q1: Since the 3500/42-01-00 is discontinued, can I still trust its reliability?

A1: Yes. Although the manufacturer transitioned to newer iterations, we supply 100% Brand New and Original units from existing stock. These units undergo the same rigorous factory testing and include our full 12-month industrial warranty.

Q2: Can I mix proximity probes and accelerometers on the same module?

A2: Yes. You can configure each of the four channels independently via the 3500 Rack Configuration Software. This flexibility allows one module to monitor both shaft vibration (via probes) and casing vibration (via accelerometers) simultaneously.

Q3: How does this module handle power-line interference?

A3: The 3500/42-01-00 features a built-in 60 Hz (or 50 Hz) notch filter. This circuitry specifically targets and eliminates electrical noise from power lines, ensuring that your vibration readings reflect actual mechanical movement rather than electrical interference.

Q4: Is any special software required for installation?

A4: You must use the Bently Nevada 3500 Rack Configuration Software to set the sensor types, alarm thresholds, and filter frequencies for the 3500/42-01-00 module before commissioning.
