Overview
Configured for non-contact shaft vibration and position measurement in the 3300 XL 8 mm Proximity Transducer System, the Bently Nevada 330104-10-20-10-02-CN (330104 proximity probe) provides direct eddy-current sensing of conductive targets. The probe uses an M10 x 1 metric thread, stainless steel armor, and a miniature coaxial ClickLoc connector.

Eddy-Current Probe Scaling and Gap Voltage
The probe generates an eddy-current response that varies with the distance between the probe tip and the conductive target. The specified nominal incremental scale factor is 7.87 V/mm, equivalent to 200 mV/mil.
For system setup, the probe must operate with the matching Proximitor Sensor and extension cable. The installed probe-to-target gap determines the resulting output voltage and measurement range. Therefore, technicians should verify the actual mechanical gap against the applicable 3300 XL system calibration requirements before commissioning.
The standard calibration target is AISI 4140 steel. Target material, probe orientation, mechanical runout, and installation geometry can affect the measured signal.
Frequently Asked Questions
Q: What target material is specified for this probe?
A: The supplied specification identifies AISI 4140 steel as the standard calibration target.
Q: What connector does the 330104-10-20-10-02-CN use?
A: It uses a gold-plated brass miniature coaxial ClickLoc connector with standard cable and no connector protector.
Q: Can the probe operate independently of the Proximitor Sensor?
A: The probe forms part of the 3300 XL 8 mm Proximity Transducer System. It operates as the sensing element with the matching Proximitor Sensor and extension cable.
Field Installation Guidelines
Install the probe with the specified M10 x 1 metric thread and maintain the required mechanical clearance around the probe body and armored cable.
Position the probe so that its sensing axis faces the conductive target within the applicable 3300 XL calibration range. Avoid mechanical contact between the probe tip and rotating machinery.
Route the armored cable separately from high-current power conductors where practical. Avoid sharp bends, excessive mechanical tension, and repeated movement at the connector interface.
Connect the miniature coaxial ClickLoc connector fully and verify its locking engagement before commissioning. Keep the connector interface clean during installation.
For vibration and position measurements, verify the probe gap, signal polarity, output voltage, and complete probe/extension-cable/Proximitor Sensor chain before placing the monitoring channel into service.
Follow the applicable machinery protection system wiring, grounding, shielding, hazardous-area, and installation requirements for the specific site.
