Hardware Specifications

Mechanical Monitoring and TSI Integration

Eddy-current probe scaling is critical for maintaining linear response across the specified measurement range. The 8 mm probe coil generates a high-frequency magnetic field, inducing eddy currents in the monitored target material. Precise gap voltage validation is necessary to ensure signal integrity, with target setpoints of -10 VDC typically applied during calibration. Cross-talk suppression must be maintained by adhering to physical separation guidelines between adjacent probe installations to ensure accurate rotor dynamics analysis without signal interference.

Field Installation Guidelines

• Mounting Requirements: Install the probe using a rigid bracket to prevent mechanical resonance. Secure with provided jam nuts after achieving the required air gap.

• Grounding: Verify electrical isolation of the probe tip from the machine housing if required by the specific monitoring topology to prevent ground loops.

• Cable Handling: Route coaxial cabling through dedicated metallic conduits to maintain signal shielding and prevent physical damage.

• Gap Calibration: Adjust the probe-to-target distance using a micrometer or feeler gauge while monitoring the output voltage at the transducer interface.

Frequently Asked Questions

• Is this probe compatible with standard 3300 XL extension cables?

  Yes, the 330130 series is fully compatible with standard 3300 XL extension cables provided the total system length requirements are met.

• What is the purpose of the "CN" suffix?

  The "CN" suffix indicates that the probe assembly is compliant with specific regional agency approvals required for operation in China.

• How is the target material accounted for?

  The probe is factory-calibrated for AISI 4140 steel. Any deviation in target material magnetic permeability requires a calibration factor adjustment.

• Can this probe operate in high-temperature zones?

  Yes, the probe is rated for operation up to 177 deg C. Ensure the installation location does not exceed these thermal limits.

• Why is the gap voltage value significant?

  Gap voltage provides the reference point for the transducer's linear operating range. Maintaining -10 VDC ensures optimal signal linearity and range.

• Does the probe require field calibration?

  The probe is calibrated at the factory. Field calibration involves verifying the gap voltage and ensuring the output matches the expected signal levels.

• Is the probe tip field-replaceable?

  The probe is a factory-sealed, single-piece assembly. If the tip or coil is damaged, the entire probe unit must be replaced.

• What is the minimum spacing for cross-talk suppression?

  Refer to the 3300 XL 8 mm installation manual for minimum distance requirements between parallel probe installations to avoid interference.
