Mechanical Monitoring & Eddy-Current Performance

The 3300 XL system employs precise eddy-current probe scaling to convert target proximity into a linear voltage signal. To maintain measurement accuracy, gap voltage validation at -10 VDC is required during cold startup to ensure the probe remains centered within its linear operating range. Rotor dynamics monitoring stability is facilitated by the Proximitor sensor internal circuit, which provides effective cross-talk suppression. This prevents signal interference when multiple probes are installed in dense radial or axial vibration configurations.

Field Installation Guidelines

• Mounting Protocol: Secure the panel mount probe to a rigid bracket; ensure the probe axis is perpendicular to the target surface.

• Torque Limits: Tighten the locking nut to 5.6 N-m; avoid overtightening to prevent deformation of the probe housing.

• Cable Integrity: Maintain a minimum 25 mm bend radius for the coaxial lead; ensure shielding is continuous to the monitor input.

• Gap Setting: Position the probe tip at a 1.27 mm nominal gap from the target surface during final calibration.

Frequently Asked Questions

• What is the linear range of this 8 mm probe?

  The linear operating range is 2.0 mm, typically calibrated between 0.25 mm and 2.29 mm from the target material.

• Is the 0.5 meter length total or probe-only?

  This represents the total system length including the probe lead, requiring a Proximitor sensor calibrated for the same length.

• Why is PPS used for the probe tip?

  Polyphenylene Sulfide (PPS) is chosen for its chemical resistance and thermal stability in industrial fluid environments.

• Can this probe be used in a vacuum?

  Yes, the probe design is capable of operating in vacuum environments provided the mounting interface is adequately sealed.

• How is cross-talk suppression achieved?

  The internal electronics of the 3300 XL system utilize frequency modulation to prevent interference between adjacent sensors.

• Is the connector waterproof?

  The ClickLoc connector is designed for industrial environments but requires additional protection if subject to direct pressurized water.

• What happens if the gap exceeds 2.29 mm?

  The signal will become non-linear and eventually lose sensitivity, resulting in inaccurate vibration readings.

• Should I apply lubricant to the threads?

  Avoid thread lubricants that contain metallic particles, as they may cause electrical shorting or interfere with system grounding.
