Configured for non-contact shaft displacement and vibration measurements in Turbine Supervisory Instrumentation systems, the Bently Nevada 330103-06-13-10-02-00 (330103 Proximity Probe) provides direct physical/electrical execution. The instrument converts changes in the high-frequency electromagnetic field emitted from the probe tip into an analog voltage output proportional to the physical gap distance between the face and the target surface.

Physical and Electrical Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

Operation of the 330103-06-13-10-02-00 sensor requires strict calibration synchronization with the matching 3300 XL Proximitor Sensor to establish exact eddy-current probe scaling. This combination maintains a linear scale factor of 7.87 V/mm (200 mV/mil) when targets match standard AISI 4140 steel. During field loop commissioning, engineers execute gap voltage validation targeting a nominal -10 VDC center-point to position the probe tip safely within the linear operating range. This step prevents cross-talk suppression failures and signal clipping under extreme rotor dynamics fluctuations.

Physical Connection and Impedance FAQ

Q: What physical precautions are necessary when mating the miniature coaxial ClickLoc connector?

A: The ClickLoc connector requires clean, dry contacts. Technicians must check that the internal pin fully seats into the receptacle without twisting the internal conductors. No tools are permitted for tightening; hand-tighten until a distinct click confirms mechanical latching.

Q: How do changes in the total system cable length affect eddy-current calibration?

A: The 3300 XL Proximitor is factory-tuned for a specific electrical length (either 5.0 meter or 9.0 meter configurations). The 1.0 meter probe cable must be extended with the appropriate non-armored extension cable to meet the design specification exactly. Mismatching system lengths alters system capacitance and invalidates the scale factor.

Q: Can the probe body withstand high-pressure fluid submersion inside machine casings?

A: The probe tip and case are sealed against typical industrial lubricating oils. However, the rear miniature coaxial connection is not pressure-sealed or fluid-impermeable and must be protected inside a dry junction box or fluid-tight conduit.

Mechanical Installation and Terminal Guidelines

• Thread Engagement Limits: Mount the M10 x 1 threaded housing through the bracket using standard mechanical clearances. Maintain a minimum of 5 full threads of engagement to secure the assembly against vibration.

• Target Material Deviations: If the observed rotor surface is not standard AISI 4140 steel, the standard eddy-current probe scaling will shift. Re-calibrate the loop using a sample block of the actual target metal to determine the modified scale factor.

• Coaxial Shield Segregation: Ensure the outer coaxial shield layer remains isolated from the machine chassis along the entire run back to the Proximitor. Grounding the shield at multiple points introduces electrical ground loops that corrupt low-level AC signals.

• Minimum Bend Radii Rules: Do not bend the 1.0 meter standard coaxial cable tighter than a 25.4 mm (1.0 inch) radius. Kinking the cable alters the internal coaxial geometry and compromises signal transmission.
