Bently Nevada 330104-06-16-50-02-00 Eddy Current Proximity Probe – 3300 Series Proximity Transducer System
When a critical rotating machine — a steam turbine, centrifugal compressor, or high-speed pump — loses its vibration monitoring signal, the consequences are immediate and severe. Without a functioning proximity probe, operators are blind to shaft displacement, orbital motion, and axial position changes. A single undetected surge event or rub condition can destroy a rotor worth hundreds of thousands of dollars and trigger unplanned downtime that costs far more. The Bently Nevada 330104-06-16-50-02-00 Proximity Transducer System exists precisely to prevent that scenario — delivering continuous, high-resolution non-contact measurement that keeps your machinery protection system fully operational.
Within the industry-standard Bently Nevada 3300 Series, the 330104-06-16-50-02-00 occupies a well-defined technical niche: a 5 mm eddy current probe with a 6-inch (152 mm) armored extension cable, 16-foot (5 m) interconnect cable, and a 50 mm driver/extension combination — configured for 2 mm gap, –24 VDC supply, and a standard output scale factor of 200 mV/mil (7.87 V/mm). This configuration is among the most widely deployed in API 670-compliant machinery protection systems globally, making it a cornerstone component in refineries, power generation plants, LNG facilities, and petrochemical complexes across six continents.

Our Quality Assurance Process
Every Bently Nevada 330104-06-16-50-02-00 unit sourced through Konmask.com undergoes a structured verification process before shipment:
- Visual Inspection: Probe tip, cable jacket, connector, and labeling checked against OEM specifications.
- Continuity & Impedance Test: Coaxial cable continuity and probe coil impedance verified within OEM tolerance.
- Documentation Review: Traceability documentation, country of origin, and batch records reviewed where available.
- Secure Packaging: Anti-static, moisture-barrier packaging with foam cushioning to prevent transit damage to the probe tip and cable assembly.
We do not sell counterfeit, refurbished-as-new, or specification-deviated parts. If a unit does not pass our checks, it is not shipped.
