Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 330106 probe utilizes high-frequency electromagnetic field oscillation to track target displacement. Accurate rotor dynamics analysis depends on precise eddy-current probe scaling; this unit is calibrated for a linear output of 7.87 V per mm (200 mV/mil). During installation, technicians must perform gap voltage validation to ensure the probe tip operates at the -10 VDC target midpoint within the 0.25 mm to 2.3 mm linear range. Internal shielding ensures cross-talk suppression in multi-probe installations, preventing signal interference between adjacent sensors monitoring the same shaft cross-section.

Installation Guidelines

• Mounting Clearance: Maintain a minimum radial clearance of 10 mm from surrounding metal to prevent false displacement readings caused by side-view effects.

• Torque Limits: Use a torque wrench on the provided jam nuts; do not exceed 5.6 Nm to avoid casing deformation.

• Cable Routing: Ensure coaxial cables are secured with ties to prevent mechanical fatigue; avoid sharp bends (minimum 25 mm radius) near the connector interface.

• Grounding: The probe casing is electrically common to the machinery housing; ensure the mounting bracket is properly bonded to the machine frame.

Frequently Asked Questions

• Is the probe tip sensitive to temperature fluctuations?

  The PPS tip is engineered for high stability. However, extreme thermal gradients can cause minor scale factor shifts, which should be accounted for in the system calibration.

• Can I replace the cable if it becomes damaged?

  No. The 330106 is a sealed assembly. Damage to the cable or the integral connector requires the replacement of the entire probe unit to maintain impedance integrity.

• How is gap voltage verified during setup?

  Connect the probe to its designated Proximitor, then measure the DC voltage at the monitor output while adjusting the gap with a precision feeler gauge or micrometer.

• Does the probe require a specific proximity sensor type?

  Yes. It must be paired with a compatible 3300 XL Proximitor sensor calibrated for 8 mm probe impedance to ensure the specified 200 mV/mil output.

• Can this probe be installed in an explosive atmosphere?

  Yes, provided the installation adheres to the system's intrinsic safety (Ex i) control drawing requirements for hazardous area classifications.

• What is the maximum output cable length?

  The total system length (Probe + Extension Cable) must be 5 or 9 meters to remain within the calibrated impedance range of the Proximitor.

• Is the connector waterproof?

  The ClickLoc connector is oil-resistant and dust-tight, but it is not rated for total water submersion or high-pressure spray cleaning.

• How do I detect a probe failure?

  Monitor the DC gap voltage. A sudden shift to the negative or positive supply rail typically indicates an open or short circuit in the probe coil or cable.
