This eccentricity monitor measures shaft bow during turbine startup and slow roll. You will find the EPRO A6220 Shaft Eccentricity Monitor providing critical data for rotor straightness assessment. Its dual-channel design supports two independent proximity probe connections.

Technical Specifications

This monitor contains two independent measurement channels with separate alarm circuits. You can also locate four relay outputs for alert and trip functions. The EPRO A6220 Shaft Eccentricity Monitor stores no battery energy for configuration retention. Instead, it uses non-volatile memory for all setpoint parameters. Therefore, this device never requires any routine battery replacement.

Measurement Details

The EPRO A6220 Shaft Eccentricity Monitor calculates rotor bow using filtered proximity probe signals. You can set alarm and trip thresholds independently for each channel. The monitor filters out vibration frequencies above 100 Hz for pure eccentricity. Moreover, each channel provides a separate 4-20 mA output for DCS integration. This design ensures safe turbine operation during critical startup phases.

Mechanical Integration and Mounting

You must mount the EPRO A6220 Shaft Eccentricity Monitor into a standard 19-inch rack or panel cutout. After positioning, secure the unit using the four front bezel screws. The monitor measures exactly 19.0 centimeters in length and 8.5 centimeters in width. Its total weight reaches approximately 1.43 kilograms for stable panel mounting. Furthermore, the front panel includes LED indicators for channel status and alarm conditions.

Environmental and Storage Guidelines

You should store this EPRO A6220 Shaft Eccentricity Monitor in a dry location away from vibration. The monitor operates reliably between -20°C and +65°C ambient temperature. Likewise, keep the unit away from conductive dust or corrosive gases. Because the monitor uses solid-state components only, it requires zero regular maintenance.
