Eddy-Current Probe Scaling and Rotor Dynamics

The 330780-90-00 functions as an oscillator/demodulator, providing a linear output scaled for 11 mm probe characteristics. For precise rotor dynamics analysis, the sensor output must be verified via gap voltage validation at the terminal strip, targeting -10 VDC when the probe is positioned at the linear range midpoint. To maintain signal integrity, cross-talk suppression is achieved by observing minimum spacing requirements between adjacent probes, which prevents mutual RF interference. The internal circuitry ensures a stable carrier signal required for detecting sub-synchronous vibrations and shaft centerline deviations in rotating machinery.

Frequently Asked Questions

Q: Does the 90 suffix indicate a specific mounting configuration?

A: Yes. The 90 suffix specifies a 9.0 metre total system length and a panel-mount configuration for the Proximitor housing.

Q: Is this sensor compatible with shorter system lengths?

A: The 330780-90-00 is factory-calibrated for a 9.0 metre system length. Utilizing a different cable length will introduce measurement inaccuracies and phase shift due to the specific impedance characteristics of the 9.0 metre configuration.

Field Installation Guidelines

Secure the Proximitor to a grounded panel. Ensure the mechanical interface is rigid to prevent vibration-induced signal noise.
Connect the probe and extension cable, ensuring the coaxial connectors are hand-tightened until firm. Avoid over-tightening as this may damage the internal dielectric or connector threads.
Route signal cabling through separate conduits from AC power or motor drive cabling to maintain the integrity of the high-frequency carrier signal.
Verify the system common connection to ensure proper grounding of the signal shield at the monitor terminal block.
Perform a system startup check by measuring the output voltage to confirm it matches the predicted gap voltage of -10 VDC for the installed probe depth.
