Core Technical Parameters

Signal Output and Rotor Dynamics Profiling

Designed for permanent mounting in harsh turbine architectures, the transducer provides stringent eddy-current probe scaling to guarantee linear conversion of shaft proximity into a measurable voltage variable. Initial field calibration mandates strict gap voltage validation (-10.0 VDC baseline targets) when interconnected with the corresponding 3300 XL Proximitor oscillator-demodulator. Coaxial RF shielding coupled with an industrial sheath guarantees cross-talk suppression and isolates the 1 MHz carrier wave from adjacent electromagnetic interference sources.

Standard Supply Bill of Materials

• 1 x Bently Nevada 330104-09-18-05-01-05 Probe Assembly
• 1 x Connector Protective Cap Cover
• 1 x M10 x 1 Hexagonal Locknut
• 1 x Factory Certification Document Insert

Mechanical Mounting Constraints

• Target Gapping Limits: Rotate the probe barrel manually until a multimeter bridged across the Proximitor outputs registers precisely -10.0 VDC, representing approximately 1.27 mm of physical gap.
• Locking Torque: Apply adequate rotational force to the locking nut to stabilize the case against heavy machine oscillation, avoiding excessive torque that could warp the inner coil.
• Routing Segregation: Maintain strict spatial isolation between the RF signal path and high-current AC motor leads to suppress inductive noise coupling in the analog loop.

Engineering and Operational FAQ

• What defines the unthreaded length of this specific transducer housing?

  The outer casing maintains a 90 mm smooth, unthreaded profile directly behind the tip, indicated by the 09 model suffix.

• How is the physical resting distance calibrated during initial commissioning?

  Field personnel must adjust the threaded engagement toward the conductive target until the Proximitor loop output rests exactly at -10.0 VDC.

• Does this physical hardware permit installation in explosive gas atmospheres?

  Yes, the 05 designation verifies that the component carries factory approvals for CSA, ATEX, and IECEx classified hazardous zones.

• What interface is utilized to bridge the probe to the extension circuit?

  The integrated pigtail ends in a miniature coaxial ClickLoc connector, designed specifically for low-loss radio frequency transmission.

• What is the defined physical span of the built-in sensor wiring?

  The integrated factory-sealed cable measures 0.5 m (1.6 ft) and features an external protective sheath to resist chemical degradation.

• Can this device output standard 4-20 mA process signals directly?

  No, this is a passive eddy-current coil that relies on a separate 3300 XL Proximitor device to generate and demodulate the RF field.

• Is it permitted to bundle the coaxial extension lines with 220 VAC power cables?

  Standard instrumentation practices prohibit this; operators must ensure a minimum 12-inch separation from high-voltage AC lines to prevent signal corruption.

• What defines the mechanical fastening standard on the outer probe shell?

  The exterior housing is machined with a standard M10 x 1 metric thread pitch to interface seamlessly with industrial mounting brackets.
