Product Description
Product Overview
The Emerson MMS 6110 is a Dual Channel Shaft Vibration Monitor, designed to provide precise vibration monitoring for rotating machinery. It features dual independent sensor inputs, configurable measurement ranges, and advanced signal processing capabilities for critical machinery protection.
Key Features
• Two independent eddy-current sensor inputs
• Configurable measurement ranges (0–400 mV to 0–8000 mV)
• Galvanically separated sensor power supply (-28V DC)
• Advanced alarm control with adjustable factors (1.0000–4.9999)
• Redundant power supply input with low power consumption (max. 6W)
• FFT voltage inputs for advanced analysis (0–10V, 10-bit resolution)
• RS-485 bus communication (supports up to 31 modules / 62 channels)
• Wide environmental tolerance (Operating: 0°C to +65°C, Storage: -30°C to +85°C)
