Overview
Configured for non-contact shaft vibration and position measurement in the 3300 XL 8 mm Proximity Transducer System, the Bently Nevada 330104-00-15-10-02-05 (330104 Proximity Probe) provides eddy-current sensing between the probe tip and a conductive machine target. The configuration uses an M10 x 1 metric thread, stainless steel armor, and a 1.0 m system length.

Eddy-Current Measurement Characteristics
The probe generates a non-contact eddy-current measurement at the conductive target. The resulting electrical output represents changes in target gap and therefore supports static position and dynamic vibration measurements. The specified 7.87 V/mm scale factor defines the nominal relationship between displacement and probe output.
The 2.0 mm linear range operates within an approximately 0.25 mm to 2.3 mm target gap. Therefore, installation should maintain the probe within the specified measurement region. The PPS tip provides the specified probe-end material, while the stainless steel armor protects the cable and probe assembly against mechanical exposure.
The configuration uses the 3300 XL ClickLoc connector system and a standard cable without a connector protector. The stated 330 N pull strength applies between the probe case and lead through the CableLoc design.
Frequently Asked Questions
Q: What measurement does the 330104-00-15-10-02-05 provide?
A: It provides non-contact eddy-current measurements of conductive-target gap changes for shaft position and vibration monitoring.
Q: What is the specified linear measurement range?
A: The specified linear range is 2.0 mm (80 mils), with the operating region stated as approximately 0.25 mm to 2.3 mm (10 to 90 mils) from the target.
Q: Does the probe require a separate power supply?
A: The supplied data does not specify power consumption for the probe itself. The probe operates as part of the 3300 XL 8 mm Proximity Transducer System.
Field Installation Guidelines
Install the probe with its M10 x 1 metric thread correctly engaged in the designated mounting location. Verify the physical clearance between the probe tip and conductive target before operating the machinery.
Maintain the probe-to-target gap within the specified linear measurement region. Avoid mechanical contact between the PPS probe tip and the rotating target.
Route the probe cable away from high-current power conductors and strong electromagnetic interference sources where practical. Maintain the cable shielding and connector arrangement specified for the complete transducer system.
Tighten and secure the probe assembly according to the applicable Bently Nevada installation documentation. Do not apply excessive tensile or bending loads to the lead. Verify the ClickLoc connector is fully engaged before commissioning.
For machinery protection applications, validate the probe output and gap condition through the associated Proximitor Sensor and monitoring system before placing the measurement channel into service.
