Epro MMS3120 Dual Channel Bearing Vibration Transmitter

Product Introduction

The Epro MMS3120 Dual Channel Bearing Vibration Transmitter is a precision module designed for continuous monitoring of bearing vibration in rotating machinery. As part of the Epro MMS3000 series, it provides two independent vibration measurement channels, making it ideal for monitoring multiple bearings simultaneously. The MMS3120 converts raw signals from proximity probes or accelerometers into standardized outputs for integration with machinery protection and condition monitoring systems.

Engineered for critical turbomachinery applications, the MMS3120 offers advanced signal processing, high accuracy, and robust noise immunity. It is widely used in turbines, compressors, motors, and generators where reliable bearing vibration monitoring is essential for safe and efficient operation.

Product Specifications

Product Applications

The Epro MMS3120 is designed for industrial applications that require precise bearing vibration measurement and protection. Typical uses include:

• Turbomachinery Monitoring: Continuous monitoring of turbine and compressor bearings.

• Generator and Motor Systems: Detects bearing faults, imbalance, and wear in large motors and generators.

• Condition Monitoring Systems: Provides real-time vibration data for diagnostics and trend analysis.

• Machinery Protection: Integrates with trip systems to prevent damage from excessive vibration.

• Oil & Gas and Power Generation: Widely deployed in critical rotating equipment in harsh industrial environments.

• Predictive Maintenance: Helps reduce unplanned downtime by identifying early signs of bearing failure.
