EPRO MMS6350 Vibration Monitoring Transmitter

Overview

The MMS6350 from the EPRO MMS6000 platform is a high-precision vibration and shaft displacement transmitter engineered for continuous protection and condition monitoring of rotating machinery. Designed specifically for turbomachinery environments, this module converts non-contact eddy current sensor signals into standardized outputs suitable for protection systems and control platforms.

By combining robust analog signal processing with integrated digital supervision, the MMS6350 delivers reliable measurement of radial shaft vibration, axial displacement, and shaft position. Its design aligns with API 670 requirements, making it appropriate for mission-critical machines where availability and measurement integrity are mandatory.

Measurement Principle and Signal Chain

The transmitter operates with EPRO PR642x series eddy current probes and corresponding CON04x signal converters. Together, they form a complete measurement chain optimized for high bandwidth dynamic response and long-term stability in harsh industrial conditions. Signal conditioning, linearization, and output generation are handled internally, minimizing external wiring complexity and noise susceptibility.

Key Technical Characteristics

The MMS6350 supports both static and dynamic shaft measurements with a wide frequency range, enabling accurate detection of vibration phenomena such as imbalance, misalignment, and rotor instability. Redundant power inputs and continuous self-diagnostics enhance system availability and reduce the risk of undetected failures.

Technical Specifications

Applications

The MMS6350 is commonly deployed in rotating equipment requiring continuous protection and diagnostics, including steam and gas turbines, centrifugal and axial compressors, large pumps, generators, and gearboxes. Its compact design allows installation close to the machine, reducing signal degradation and improving measurement fidelity.
