epro MMS3210/020-020 — Dual-Channel Shaft Displacement / Vibration Monitor
The MMS3210/020-020 is a dual-channel shaft displacement (radial
vibration) monitor card from epro GmbH (Germany), part of epro’s MMS 3000 machinery protection and condition-monitoring system. It measures
the relative displacement between a rotating shaft and its bearings — i.e. shaft
vibration — using two eddy-current (proximity) probe inputs, and outputs the processed
signals to the plant’s protection/monitoring system. The MMS3210 model
identifies the card, and the /020-020 suffix denotes this specific
configuration variant — a sibling of the earlier MMS3210/010-000 in the same
list. Manufactured by epro (an Emerson company). Typically used as a genuine spare for
existing MMS 3000 installations.
- epro MMS 3000 machinery protection / condition-monitoring card
- Dual-channel shaft displacement (radial vibration) monitor
- Eddy-current / proximity probe inputs
- Model MMS3210, configuration /020-020
- Sibling variant of MMS3210/010-000
Key Features & Functions
Dual-Channel Monitoring
Monitors two independent measurement channels, typically the two radial directions (e.g. X/Y) of one shaft or bearing position.
Shaft Displacement Measurement
Measures relative shaft vibration/displacement against the bearing using eddy-current proximity probes, a primary parameter for rotating-machinery health.
Protection & Condition Monitoring
Provides processed measurement outputs and alarm/trip functions within the MMS 3000 system for machine protection and predictive maintenance.
MMS 3000 System Integration
Designed to slot into the epro MMS 3000 rack, working alongside other measurement and relay/communication modules.
Technical Specifications

Source note: The MMS3210 card is confirmed as a dual-channel shaft
displacement / vibration monitor in epro’s MMS 3000 series. The /020-020
suffix is a different configuration from the /010-000 variant seen earlier
in this list — the exact difference between these configurations, along with measurement
range, probe compatibility and system version, must be confirmed against the official epro
datasheet before purchase.
Typical Application Scenarios
- Steam & Gas Turbine Monitoring: shaft vibration measurement on turbines.
- Compressor & Pump Protection: monitoring shaft displacement on rotating equipment.
- Generator Monitoring: radial vibration measurement on generators and large motors.
- Machine Protection Systems: feeding alarm/trip logic for critical machinery.
- Predictive Maintenance: supporting condition monitoring and early fault detection.
Frequently Asked Questions
What is the epro MMS3210/020-020?
It is a dual-channel shaft displacement (radial vibration) monitor card — configuration /020-020 — from epro’s MMS 3000 machinery protection and condition-monitoring system.
How does it differ from MMS3210/010-000?
Both are MMS3210 dual-channel shaft displacement monitors; only the configuration suffix
differs (/020-020 vs /010-000). The precise difference should be
confirmed in the official epro documentation.
Is it a Bently Nevada part?
No — it is an epro product (epro is an Emerson company). Both epro and Bently Nevada make rotating-machinery protection equipment, so they share the application domain, but they are distinct brands and systems.
Which probes does it use?
It uses eddy-current (proximity) probes for shaft displacement measurement. Confirm the exact probe model and system matching in the epro datasheet.
Where can I find the official datasheet?
Official technical documentation is available from epro and authorized distributors. Verify all specifications there before purchase.
