The Bently Nevada Model 330104-00-05-10-02-00 Eddy Current Proximity Probe is a core component of the industry-standard 3300 XL 8 mm Proximity Transducer System engineered and manufactured by Bently Nevada (a Baker Hughes business). Regarded globally as the benchmark for critical machinery protection, this non-contacting transducer system fully complies with the American Petroleum Institute API 670 Standard for mechanical design, linear measurement range, accuracy, and thermal stability in turbomachinery applications.

Operating on the eddy current sensing principle, the 330104 probe emits a high-frequency electromagnetic field from its sensing tip. When positioned near a conductive metallic target (standard calibration target: AISI 4140 steel), variations in gap distance generate proportional voltage changes with a calibrated sensitivity of 7.87 V/mm (200 mV/mil). The system provides continuous measurement capabilities for both static positions (thrust position, journal bearing wear, thermal growth) and dynamic dynamic behavior (radial vibration, peak-to-peak displacement, and Keyphasor rotational timing marks).

Configuration Breakdown for Model 330104-00-05-10-02-00:
- 330104: 3300 XL 8 mm Proximity Probe with metric M10x1 case threads and integrated stainless steel protective armor tubing.
- 00 (Unthreaded Length Option): 0 mm unthreaded length (fully threaded case).
- 05 (Overall Case Length Option): 50 mm overall case length.
- 10 (Total Length Option): 1.0 meter (3.3 feet) integrated cable length.
- 02 (Connector and Cable-Type Option): Miniature coaxial ClickLoc gold-plated connector with standard stainless steel armored cable.
- 00 (Agency Approval Option): Standard industrial unapproved version (No hazardous area certification required).

The probe tip utilizes Bently Nevada's patented TipLoc molding technology with high-strength polyphenylene sulfide (PPS) engineering polymers, providing robust resistance against hot turbine lubricants, synthetic fluids, and mechanical fluid shear. A defining advantage of the 3300 XL platform is its complete interchangeability: probes, extension cables, and Proximitor sensors can be freely interchanged in the field without the need for individual component matching or bench recalibration.
