1. Product Description The BENTLY NEVADA 3500/25 149369-01 is a high-performance Enhanced Keyphasor Module designed for rotating machinery health monitoring in industrial applications. As part of the 3500 Monitoring System, it provides precise synchronization of vibration and process data by converting analog signals from proximity probes or magnetic pickups into digital keyphasor signals. This module supports up to two channels, enabling accurate detection of shaft rotation markers for phase analysis, speed measurements, and fault diagnostics. With its compact half-height design and hot-swap capability, the 149369-01 ensures easy integration and maintenance in power plants, oil refineries, and manufacturing facilities.

3. Advantages and Features
Dual-Channel Precision: Simultaneously processes two keyphasor signals for redundant shaft alignment verification.
Hot-Swap Capability: Modules can be replaced without powering down the system, minimizing downtime.
Flexible Inputs: Supports both proximity probes and magnetic pickups for versatile sensor integration.
Bulkhead Mounting: Optional wall-mounted installation for space-constrained environments.
Enhanced Data Output: Provides 8 proportional values per channel (e.g., 1X/2X amplitude/phase) for advanced diagnostics.
4. Application Areas and Use Cases Industry Applications:
Power Generation: Steam turbines and generators.
Oil & Gas: Compressors and pumps in offshore platforms.
Manufacturing: High-speed rotating machinery.
Case Study: A European steel mill reduced unplanned downtime by 25% using the 149369-01 to monitor roll mill vibrations. Early detection of misalignment via phase analysis allowed predictive maintenance, saving €600,000 annually.
5. Competitor Comparison
Higher Channel Density: Dual-channel design offers twice the capacity of single-channel alternatives.
Advanced Diagnostics: Generates more proportional values (8 vs. 4–6 in 竞品) for comprehensive analysis.
System Compatibility: Ensure alignment with 3500 Series racks and 3500/42M monitors.
Input Type: Choose between proximity probe or magnetic pickup inputs based on existing sensor infrastructure.
Space Requirements: Opt for bulkhead mounting if rear access to the rack is limited.
7. Precautions
Installation: Install in front slots only; avoid rear slots to prevent signal interference.
Sensor Calibration: Regularly verify sensor alignment and signal integrity to maintain accuracy.
Firmware Updates: Apply BENTLY-recommended firmware updates to access new features and security patches.
