Eddy-Current Probe Scaling and Rotor Dynamics

The 330878-90-05 sensor facilitates the translation of probe gap variations into linear voltage outputs, which are utilized for monitoring rotor dynamics. Effective measurement requires precise gap voltage validation, with a standard target of -10 VDC when the probe is set to the electrical center of its linear range. Deviation from this target suggests improper probe installation or target surface non-conformity. Furthermore, to maintain signal integrity in multi-channel installations, cross-talk suppression must be enforced by observing strictly defined physical spacing between adjacent probes to prevent electromagnetic interference from skewing the displacement data.

Frequently Asked Questions

Q: Can the 9.0 meter system length be modified for installation needs?

A: No. The system length is factory-calibrated to account for the electrical capacitance of the coaxial cable. Cutting or extending the cable alters this capacitance, introducing significant measurement errors and requiring a full recalibration of the probe-cable-sensor system.

Q: Are there restrictions on the panel mount installation?

A: The sensor housing should be installed to ensure the A380 aluminum body maintains a low-impedance ground path to the monitor chassis. Improper grounding may introduce common-mode noise, affecting the low-level signal output.

Field Installation Guidelines

Ensure the panel mounting surface is clean and conductive to facilitate a secure electrical bond for the sensor housing.
Verify that the system length indicated on the Proximitor matches the total length of the installed extension cable and probe.
Route coaxial cabling through dedicated conduit, keeping a minimum distance of 30 cm from high-power AC lines to prevent induced noise.
Tighten all coaxial connectors using a torque wrench or finger-tight plus one-quarter turn; overtightening can deform the connector dielectric and lead to signal degradation.
Perform an initial gap voltage verification using a feeler gauge and a sample of the actual machine shaft material before final calibration of the monitoring system.
