Eddy-Current Probe Scaling and Rotor Dynamics Signal Processing

The 1900/65 monitor processes machinery condition signals associated with vibration and rotational speed measurements. The vibration input architecture supports voltage-based monitoring channels with defined filtering characteristics for dynamic machinery signals. The monitor can be integrated with eddy-current probe measurement systems where probe scaling and gap voltage validation are required for shaft displacement monitoring.

The proximity measurement interface requires verification of probe operating conditions, including gap voltage targets commonly referenced around -10 VDC for eddy-current probe systems. Proper probe scaling configuration allows accurate interpretation of shaft movement signals related to rotor dynamics, including vibration amplitude and rotational behavior.

The input filtering design provides separation between low-frequency bias components and higher-frequency vibration signals, supporting measurement stability in rotating equipment monitoring applications.
