Configured for contactless displacement monitoring in 3500 Machinery Protection Systems, the Bently Nevada 330103-00-14-10-02-CN (330103 Proximity Probe) provides direct physical/electrical execution. The component converts the proximity gap between the probe tip and a rotating metallic target into a proportional analog voltage signal. This signal is processed by an external Proximitor sensor to derive precise data regarding shaft radial vibration, axial position, and rotational speed within critical rotating assets.

Hardware Technical Specifications

Mechanical Monitoring & Eddy-Current Integrity

Operation of the 3300 XL transducer requires consistent eddy-current probe scaling to ensure the electrical output accurately reflects rotor dynamics. During installation, field engineers must execute gap voltage validation, targeting -10 VDC at the mechanical center of the linear range. This alignment ensures the signal remains within the dynamic window of the 3500 monitor. Furthermore, effective cross-talk suppression is achieved by observing minimum physical separation distances between adjacent probe tips, preventing inductive interference that could otherwise skew phase-angle and vibration amplitude measurements.

Technical Query Resolution

• What is the effect of probe contact with the target shaft?

  Contact causes physical damage to the tip and internal coil; the Proximitor sensor will detect an electrical discontinuity and output a fault voltage, flagging a NOT OK status.

• Is the 330103 probe compatible with non-3300 XL extension cables?

  No, components must be matched to the 3300 XL generation to ensure correct system impedance and maintain the 7.87 V/mm scale factor consistency.

• Can this probe function in submerged oil environments?

  Yes, the probe tip and cable assembly are rated for full immersion in standard machine lubricating oils, provided the connector is protected with the silicone sleeve.

• What is the maximum allowed bend radius for the integral cable?

  The non-armored cable must not be bent tighter than a 25.4 mm (1.0 inch) radius to prevent internal degradation of the coaxial dielectric.

• How does the -CN suffix impact international application?

  The -CN suffix denotes regional compliance certification; check local hazardous area requirements before installing in certified explosive atmospheres.

• Why does the probe output voltage increase as the shaft moves away?

  The probe acts as an inductive sensor; as the target moves away, the loading on the oscillator circuit decreases, causing the gap voltage to move toward -24 VDC.

• Are there specific limitations for mounting the probe in non-ferrous housings?

  Yes, proximity probes must be mounted in conductive material; non-conductive mounting requires a metallic sleeve or custom bracket to provide an electrical reference.

• Can the probe be calibrated for non-steel targets?

  It is possible to calibrate for other materials, but the output linearity and scale factor will shift, requiring a dedicated calibration curve for the Proximitor system.
