Eddy-Current Scaling and Rotor Dynamics Measurement

The 330104-00-05-50-11-00 uses an eddy-current sensing principle to convert shaft displacement into a proportional electrical output through a compatible 3300 XL Proximitor Sensor. The probe maintains a 7.87 V/mm scale factor across its 2.0 mm linear measurement range.

Furthermore, the system evaluates rotor dynamics parameters by measuring radial vibration, shaft position, and mechanical movement. The probe gap voltage must be validated during installation, with the typical operating target centered around the -10 VDC range when connected to the Proximitor system. Proper gap adjustment ensures correct signal scaling and displacement measurement accuracy.

The probe design incorporates TipLoc molding and CableLoc construction. In addition, the FluidLoc cable structure prevents oil and process fluid migration through the cable core, maintaining signal integrity in rotating equipment environments.

Frequently Asked Questions

Q: Can the 330104-00-05-50-11-00 probe operate without a Proximitor Sensor?
A: No. The probe requires a compatible 3300 XL Proximitor Sensor to provide excitation and convert eddy-current impedance changes into a proportional voltage output.

Q: What installation parameter must be checked before operation?
A: The probe installation requires verification of mechanical gap and gap voltage. The final gap setting should match the Proximitor Sensor operating range, commonly validated near -10 VDC.

Q: What cable feature prevents liquid migration?
A: The FluidLoc cable design blocks oil and process fluid movement through the internal cable structure, reducing the risk of contamination at the connection point.

Field Installation Guidelines

• Install the probe with the M10 x 1 threaded body fully secured against the mounting surface.
• Align the probe tip perpendicular to the conductive target surface to maintain correct eddy-current measurement geometry.
• Verify probe gap voltage after mechanical installation and before connecting the monitoring channel to operational machinery.
• Route the coaxial cable away from high-current power cables and strong electromagnetic interference sources.
• Maintain proper connector engagement when installing the miniature ClickLoc connector to prevent signal interruption caused by vibration.
• Connect cable shielding according to the monitoring system grounding practice to reduce electrical noise.
