Overview
Configured for non-contact shaft position and vibration measurement in a 3300 XL 8 mm proximity transducer system, the Bently Nevada 330104-00-18-10-02-05 (330104 Proximity Probe) converts probe-to-target gap changes into an electrical signal for machinery monitoring. The probe uses eddy-current measurement and supports radial vibration, shaft position, and related rotating-machinery measurements when paired with the specified Proximitor Sensor and extension cable.

Eddy-Current Measurement and Gap Scaling
The probe senses the electrical interaction between its tip and a conductive target. As the target moves relative to the probe tip, the system changes the resulting electrical output. The compatible Proximitor Sensor converts this gap-dependent response into a voltage signal used for shaft position and vibration measurement.
For installation and verification, technicians should validate the complete probe, extension cable, and Proximitor Sensor combination as a matched transducer system. The stated 7.87 V/mm ISF defines the nominal incremental output scaling within the specified measurement range.
The 3300 XL construction uses a PPS probe tip and AISI 304 stainless steel case. The supplied connector configuration includes a miniature coaxial connector and connector protector.

Field Installation Guidelines
Install the probe so that its sensing axis follows the intended shaft or target measurement direction. Maintain the specified mechanical gap required by the complete 3300 XL transducer system.
Route the probe cable away from high-current power conductors, switching devices, and other sources of electrical interference. Avoid unnecessary cable loops and mechanical strain at the connector.
Use the specified miniature coaxial connector and connector protector. Keep mating surfaces clean and dry during installation, and secure the cable against vibration without applying excessive force to the connector.
For machinery vibration measurements, verify probe orientation, target condition, mechanical clearance, cable continuity, and the complete transducer-chain calibration before placing the monitoring channel into service.
