Description Reviews

The Bently Nevada 330103-00-03-50-02-00 (wait, correction: 330100-50-03), also cataloged as the 330100 Proximity Sensors, operates as a dedicated hardware component for continuous non-contact radial vibration and axial position signal conditioning within 3300 Transducer System platforms. It supplies high-frequency radio frequency excitation to an eddy-current proximity probe and processes the reflected RF modulation into proportional DC and AC voltage outputs.

Eddy-Current Probe Scaling & Rotor Dynamics

The 330100-50-03 conditions raw transducer signals to maintain precise eddy-current probe scaling at a standard 7.87 V/mm (200 mV/mil) output ratio across its linear range. Calibration is internally matched for a 5.0-meter overall system configuration comprising probe, extension cable, and sensor. During field alignment, technicians verify proper gap voltage validation targeting -10 VDC at static shaft centerline to provide symmetrical dynamic headroom for transient vibration excursions and maximize cross-talk suppression in multi-channel rotor dynamics setups.

Frequently Asked Questions

Q: What requires the Proximitor sensor total length option (-50) to match cable length?

A: The internal tank circuit oscillator is factory-tuned to the exact capacitance and inductance of a 5.0-meter system length. Mismatched cable lengths degrade output sensitivity scaling away from the nominal 200 mV/mil specification.

Q: How is ground isolation maintained at the A383 aluminum housing base?

A: The A383 aluminum housing is mounted using insulated hardware or mounted within a protective fiberglass enclosure to prevent ground loop currents from interfering with the low-level signal loop.

Q: Can the 330100-50-03 operate in hazardous classified locations?

A: Yes, the -03 suffix indicates multi-agency approvals including CSA, ATEX, and IECEx certification for installation in hazardous areas when connected through approved intrinsically safe barriers.

Field Installation Guidelines

Mount the A383 aluminum Proximitor sensor housing onto a standard DIN rail or panel plate inside a weather-tight protective junction box.
Ensure the base of the sensor is electrically isolated from local structural ground to eliminate stray current ground loops.
Connect the 5.0-meter system extension cable miniature coaxial lead directly to the input terminal, ensuring the ClickLoc connector is securely hand-tightened.
Wire the output terminals using twisted, shielded three-conductor cable back to the 3500 or 3300 monitoring rack monitor card.
Terminate the cable shield strictly at the monitor rack end; leave the shield floating and insulated at the Proximitor housing junction box.
