The Bently Nevada 330709-000-070-10-02-00, also cataloged as the 330709 3300 XL 11 mm Probe proximity probe, operates as a displacement sensing transducer for eddy-current based vibration and position measurement within Bently Nevada 3300 XL monitoring architectures. The probe converts target shaft surface proximity variation into analog gap voltage signals transmitted through a coaxial ClickLoc interface for downstream conditioning modules. Mechanical thread engagement (M16 x 1.5) defines mounting geometry, while linear sensing behavior is referenced against calibrated gap voltage scaling used for rotor dynamic displacement reconstruction.

Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Behavior

The probe operates using eddy-current field interaction between the probe tip and conductive shaft surface. Output sensitivity is proportional to target distance variation within calibrated linear range, typically referenced against gap voltage scaling behavior near negative voltage bias regions (around -10 VDC system calibration reference in compatible monitoring systems). Signal integrity depends on controlled impedance transmission along the coaxial path, with shielding continuity required to prevent phase distortion and amplitude drift in high-frequency rotor displacement measurement.
