Configured for high-frequency non-contact shaft displacement and relative vibration monitoring in 3300 XL Transducer System platforms, the Bently Nevada 330103-00-03-50-02-00 (330103 Proximity Sensors) provides direct physical/electrical execution. It projects an alternating radio frequency magnetic field through its polyphenylene sulfide tip to measure physical gaps relative to rotating shaft target surfaces.

Eddy-Current Probe Scaling & Rotor Dynamics
The 330103-00-03-50-02-00 probe incorporates an integrated 5.0-meter continuous coaxial cable lead to route high-frequency excitation signals directly to a matching 5.0-meter 3300 XL Proximitor sensor without requiring an intermediate extension cable. Controlled coil geometry maintains precise eddy-current probe scaling at a linear 7.87 V/mm (200 mV/mil) sensitivity factor. Setting the mechanical probe gap to match a target -10 VDC gap voltage baseline establishes ideal center positioning, ensuring low cross-talk suppression and continuous precision when measuring dynamic rotor dynamics.
Frequently Asked Questions
Q: Why does this probe model not require a separate extension cable?
A: Option -50 designates an integrated 5.0-meter continuous coaxial cable built directly onto the probe body, allowing direct termination at a 5.0-meter Proximitor sensor without inter-cable connection resistance.
Q: How does the ClickLoc connector mechanism maintain contact stability?
A: The ClickLoc miniature coaxial connector incorporates a spring-loaded friction ring that snaps over the female matching port, locking the physical connection against rotational back-off caused by machinery vibration.
Q: What purpose does the internal Viton O-ring serve?
A: The Viton O-ring seals differential pressure between the polyphenylene sulfide probe tip and the stainless steel case, preventing process fluid ingress through the internal probe casing structure.
Field Installation Guidelines
- Inspect the 3/8-24 UNF threaded mounting bore for burrs, debris, and thread integrity prior to probe insertion.
- Thread the 30 mm probe body into the mounting hole by hand. Connect the lead to the 3300 XL Proximitor sensor and monitor output voltage with a multimeter.
- Adjust probe depth to achieve the target -10 VDC gap voltage baseline at nominal machine shaft resting position.
- Torque the external locknut against the mounting face to secure the mechanical setting without twisting the cable egress point.
- Route the 5.0-meter coaxial cable through dedicated metallic conduit, ensuring a minimum bend radius of 25 mm (1.0 inch) is maintained throughout the run to prevent coaxial shield deformation.
