General Information

• Manufacturer Bently Nevada
• Part Number 3500/25-PWA149369-01
• Product Type Enhanced Keyphasor Module
• Series 3500 System

Description

 This module serves to detect the precise timing of shaft rotations by converting input signals from proximity probes or magnetic pickups into digital Keyphasor signals. These signals are essential for various monitoring functions, including

• Shaft Speed Measurement Provides accurate measurement of shaft rotational speed, enabling detection of abnormal speed fluctuations or trends.
• Vibration Phase Analysis Facilitates the analysis of vibration phase data, which is critical for identifying and diagnosing machinery faults and defects.
• Orbit Analysis Enables the creation of orbit plots, which visually represent the motion of a rotating shaft and can reveal potential bearing or alignment issues.

Key Features

• Enhanced Signal Processing Offers improved signal processing capabilities compared to previous Keyphasor modules, resulting in more accurate and reliable data.
• Expanded Input Range Supports a wider range of input signal amplitudes, accommodating various sensor types and operating conditions.
• Dual-Channel Operation Provides two independent channels for simultaneous monitoring of two shafts or two positions on a single shaft.
• Compact Design Features a compact half-height form factor, allowing for space-efficient installation within the 3500 rack.
