Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

The 3300 XL 8 mm probe forms part of a calibrated proximity transducer system consisting of a probe, extension cable, and Proximitor sensor. The specified scale factor of 200 mV/mil establishes the displacement-to-voltage relationship used by monitoring systems for shaft vibration and position measurements.

During commissioning, gap voltage verification is commonly performed to confirm the probe operates within the calibrated linear measurement region. Proper gap adjustment supports measurement accuracy and assists in maintaining valid displacement data for rotor dynamic evaluation. Typical transducer verification procedures include confirmation of expected negative bias voltage levels before machinery startup.

Frequently Asked Questions

Q: Can the 330103-00-02-15-12-05 be used without a Proximitor sensor?
A: No. The probe is intended to operate as part of a complete 3300 XL proximity transducer system that includes a compatible extension cable and Proximitor sensor.

Q: What measurement range is provided by the probe?
A: The probe provides a linear measurement range of 2.0 mm (80 mils) when used within the specified 3300 XL transducer system.

Q: Is the probe approved for installations requiring hazardous-area certifications?
A: Yes. This configuration includes CSA, ATEX, and IECEx approval options as identified by the -05 suffix.

Field Installation Guidelines

• Verify probe, extension cable, and Proximitor sensor compatibility before installation.

• Maintain the specified probe-to-target gap during commissioning.

• Route probe cables separately from motor power and high-current conductors.

• Prevent excessive bending or mechanical stress on the FluidLoc cable assembly.

• Maintain shield continuity and grounding practices according to plant instrumentation standards.

• Verify connector engagement at the ClickLoc interface before energizing the monitoring channel.

• Confirm gap voltage values and channel calibration after installation.

• Inspect the probe tip and mounting threads for physical damage before placing equipment into service.
