Product Description

Overview

The A6110 by EPRO (MMS 6000 series) is a high-precision, dual-channel Shaft Relative Vibration Monitor. Designed for critical rotating machinery, it continuously tracks shaft displacement, vibration, and eccentricity. The module is essential for protecting turbines, compressors, and hydro machinery by detecting mechanical issues such as misalignment, unbalance, or bearing wear before they escalate into serious failures.

Key Features

• Two independent channels with configurable monitoring modes (X/Y shaft orbit or separate bearing points)

• Hot-swappable 1-slot 3U rack module for uninterrupted machinery protection

• Compatible with standard eddy current probes: PR6422, PR6423, PR6424, PR6426

• Adjustable frequency response from 1 Hz to 16 kHz, ensuring both low-speed and high-speed vibration capture

• Programmable alert and danger setpoints with dedicated LED indicators

• Galvanically isolated sensor inputs with high input resistance (>100 kΩ)

• Buffered sensor supply (-26.7 V DC nominal, 20 mA typical, 35 mA max) with short/open-circuit protection

• Front-panel SMB connectors provide live analog output for advanced diagnostic analysis

• RS-232/RS-485 interface for parameter configuration and remote monitoring

Technical Specifications

Applications

• Turbine & Compressor Protection: Monitors shaft displacement to prevent bearing or seal damage

• Shaft Eccentricity Tracking: Detects thermal or mechanical shaft bow during operation

• Predictive Maintenance: Supports trend analysis to forecast maintenance needs

• Dual-Plane Shaft Monitoring: Measures vibration in X/Y planes for shaft orbit analysis
