Gap Voltage Validation and Eddy-Current Probe Scaling

The probe must be paired with a matched 3300 XL extension cable and driver (proximitor) to maintain factory-calibrated eddy-current scaling of 200 mV/mil (7.87 mV/um). Gap voltage at the target setpoint is nominally -10 VDC; deviation indicates improper probe-to-shaft clearance or mismatched system components. Cross-talk between adjacent probes is suppressed by maintaining minimum center-to-center spacing per Bently Nevada installation guidelines and verifying shielded cable integrity.

Frequently Asked Questions

Q: Can this 1.2 in case length probe replace a 330101 with 1.0 in case length in the same mounting hole?

A: Yes, provided the machined bore depth accommodates the additional 0.2 in case length. Verify that the unthreaded length option (0.0 in) matches the application requirement to avoid probe tip bottoming out on the shaft.

Q: Is the probe polarity-sensitive when connecting to the driver module?

A: No. The miniature coaxial ClickLoc connector enforces correct pinout. Mating must be done with the 3300 XL driver module only to preserve calibrated scaling.

Q: Does the absence of armor affect EMI performance?

A: Unarmored standard cable relies on proper shield termination at one end (driver side). Route separately from power and switching circuits to maintain signal-to-noise ratio.

Field Installation Guidelines

Mount the probe perpendicular to the conductive target surface. Engage a minimum of 5 full threads of the 3/8-24 UNF fitting into the machine housing. Terminate the coaxial shield drain wire at the driver module end only—leave the probe-end shield floating—to prevent ground loops. Measure gap voltage after final tightening and confirm it falls near -10 VDC before placing machinery in service. Do not exceed the specified minimum bend radius of 25 mm for the coaxial cable.
