MMS 6220 Dual Channel Eccentricity Monitor
The MMS 6220 dual channel eccentricity monitor processes relative radial shaft vibration signals of eddy current sensors with the following signal evaluations:
- peak – peak
- minimum / maximum
These measurements serve the construction of turbine protection systems.
They provide signals for analysis and diagnosis systems to be further processed in field bus systems host computers and networks.

FAQ About EPRO MMS 6220
Q1: How does the EPRO MMS 6220 leverage its dual-channel architecture to enhance the fidelity of shaft vibration and displacement monitoring?
A: The EPRO MMS 6220 features two independent differential signal inputs for eddy current measuring chains, enabling highly accurate acquisition of dynamic machine parameters while maintaining galvanic isolation from the power supply.
Q2: Why is the EPRO MMS 6220 particularly well-suited for safeguarding critical rotating machinery during transient operating conditions?
A: The EPRO MMS 6220 incorporates an adjustable measuring-range multiplier from 1.000 to 4.999, allowing alarm thresholds to be dynamically adapted during machine run-up and run-down phases, thereby reducing nuisance trips while preserving protection integrity.
Q3: What diagnostic and signal-conditioning capabilities distinguish the EPRO MMS 6220 in advanced turbomachinery monitoring applications?
A: The EPRO MMS 6220 supports a wide signal voltage range from 0–400 mVpeak up to 0–8000 mVpeak, offers input impedance of ≥100 kΩ, and processes frequencies from 0.017 to 70 Hz (1.02–4200 rpm), ensuring exceptional measurement flexibility across diverse machinery types.
Q4: How does the EPRO MMS 6220 ensure reliable sensor operation in electrically demanding industrial environments?
A: The EPRO MMS 6220 provides galvanically isolated sensor supplies with a nominal output voltage of -26.7 VDC, while incorporating open-circuit and short-circuit protection. This architecture allows parallel connection with additional monitors without signal degradation or mutual interference.
Q5: Which advanced control and synchronization functions make the EPRO MMS 6220 a valuable asset within integrated machine protection systems?
A: The EPRO MMS 6220 features configurable 24 V logic control inputs, selectable open-circuit or closed-circuit operating modes, monitor locking functionality, dedicated key pulse inputs for rotational synchronization, and dual 0–10 V voltage inputs with 10-bit resolution, enabling precise machine supervision and alarm management.
