EPRO MMS6120 9100-00002-10 High-Precision Dual Channel Shaft Displacement Monitor
This dual-channel displacement monitor delivers critical protection for rotating machinery in demanding industrial environments. Designed to track shaft movement with extreme accuracy, it helps prevent catastrophic failures in turbines, compressors, and pumps where even microns of deviation matter.

Commonly deployed in power generation turbines and oil & gas compressors, this monitor integrates seamlessly with Bently Nevada 3500 systems and GE Fanuc vibration protection setups. We frequently pair it with 3500/44 displacement transducers and 3500/20M monitors for complete shaft position monitoring solutions. Field engineers appreciate its compatibility with existing PLC systems through standard 4-20mA output connections.
What sets this unit apart is its dual independent measurement channels with automatic channel comparison – if one circuit drifts beyond 0.5 microns, the system flags potential sensor issues before false readings occur. The built-in watchdog timer detects internal faults within 10 seconds, faster than most competitors’ systems. Unlike typical monitors requiring dedicated signal conditioners, this unit directly accepts signals from standard proximity probes without external amplifiers.
Engineers in the field often mention how the setup process only takes a few minutes thanks to the intuitive interface. One technician noted, “After installing dozens of these on gas turbines, we’ve never had a false trip – even during voltage dips that dropped power to 11VDC briefly.”
This monitor’s combination of sub-micron accuracy, dual-channel verification, and industrial-grade durability makes it ideal for critical machinery protection. Its compact 1U rack mount design saves panel space while maintaining easy front-panel access to calibration controls. With proven performance in environments exceeding 85°C ambient temperatures, it outperforms similar units that require climate-controlled enclosures.
