The Bently Nevada 330180-X1-CN MOD:143416-29, also cataloged as the 330180-X1-CN Proximitor Sensor, operates as a dedicated hardware component for signal conditioning of eddy-current transducer inputs within machine monitoring platforms.

Model Suffix and Modification Matrix

• X1: Factory-calibrated system length configuration (1.0 m, 5.0 m, or 9.0 m).
• CN: Standard agency approval configuration.
• MOD:143416-29: Custom factory modification code for specific input/output impedance tailoring.

Hardware Specifications

Mechanical Monitoring and Eddy-Current Scaling

The 3300 XL Proximitor processes high-frequency carrier signals to determine the gap between the probe tip and the shaft target. The unit maintains consistent eddy-current probe scaling, providing a linear voltage output of -2 VDC to -18 VDC. During system commissioning, gap voltage validation at the terminal block is required to confirm the sensor is operating at the target -10 VDC center-point. The internal demodulation circuitry is engineered for cross-talk suppression, ensuring that adjacent probe channels in high-density mounting configurations do not introduce electromagnetic interference into the rotor dynamics signal.

Field Installation Guidelines

• Mounting
  • Attach the sensor to a 35 mm DIN-rail or bulkhead mount inside an environmentally protected cabinet.
• Grounding
  • Connect the chassis to a dedicated instrumentation ground to maintain immunity against RFI and EMI.
• Wiring
  • Use high-quality coaxial cabling from the probe to the Proximitor input to maintain impedance matching.
  • Route signal wires through dedicated conduits separate from AC power and high-current drive cables.

Frequently Asked Questions

• Can this Proximitor be used for extended range measurements up to 1000 mils?

  Yes, the hardware supports extended range applications up to 1000 mils, provided the associated probes and cabling are calibrated for that specific measurement span.

• What does the MOD:143416-29 signify for my installation?

  This is a specific factory modification. Do not substitute this unit with a standard 330180-X1-CN without verifying impedance compatibility with your existing system.

• How does the Proximitor handle phase delay?

  The hardware is optimized for minimal phase distortion, maintaining a phase delay of less than 1 deg at a frequency of 1 kHz.

• Is this Proximitor compatible with current output systems?

  While the primary output is voltage-based (-2 VDC to -18 VDC), the system supports optional 4-20 mA output configurations for PLC/DCS integration.

• Why must the system length (X1) match the installed probe?

  The Proximitor is factory-tuned to the specific inductance and capacitance of the probe/cable assembly; mismatches will cause significant linearity and calibration errors.

• What is the response to temperature variations within the specified range?

  The circuitry is compensated for operation between -52 deg C and +100 deg C; maintain these limits to ensure consistent signal drift performance.

• How do I perform a field check of the Proximitor output?

  Connect a digital multimeter to the output terminals and verify the voltage corresponds to the actual probe-to-target physical gap.

• Does the unit support hot-swapping?

  The terminal blocks can be disconnected; however, it is standard practice to isolate power before removing or installing the Proximitor to prevent signal transients.
