Hardware Specifications

Mechanical Monitoring and TSI Integration

Eddy-current probe scaling is required to maintain output linearity across the measurement range. Site commissioning must include gap voltage validation, targeting -10 VDC at the mid-point of the linear operating range. Maintaining rotor dynamics data integrity requires strict cross-talk suppression by adhering to the manufacturer-specified minimum probe separation distances to prevent carrier signal interference. The transducer assembly maintains high signal fidelity when properly shielded and grounded in accordance with industry standard instrumentation practices.

Field Installation Guidelines

• Mounting: Install the probe into a rigid bracket, ensuring the jam nuts are torqued to prevent movement due to vibration.

• Grounding: Ensure electrical isolation of the probe housing from the machine case unless specific site topology requires a bonded ground.

• Signal Path: Route the coaxial cable through a metallic conduit to provide shielding against electromagnetic noise and physical protection.

• Gap Setting: Calibrate the air gap with a feeler gauge and confirm the output voltage at the proximitor terminal matches the nominal operating target.

Frequently Asked Questions

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

  Yes, the 330101 probe is designed to integrate with 3300 XL extension cables provided the system length is correctly matched to the proximitor calibration.

• What is the standard target material for this probe?

  The probe is factory-calibrated for AISI 4140 steel. Using other materials will result in sensitivity deviations and require field calibration.

• Can the probe tip be physically touched by the rotating shaft?

  No. Physical contact will damage the probe tip and disrupt the eddy-current field. A proper air gap must be maintained during all phases of operation.

• How should signal noise be addressed during installation?

  Check for ground loops and verify that the coaxial shielding is intact and properly connected through the entire signal path to the monitor.

• What is the maximum operating temperature?

  The probe is rated for operation up to 177 deg C. Operating beyond this limit will degrade internal components and lead to signal drift or failure.

• Are the connector pins field-repairable?

  No. The connector is factory-swaged. If the connector is damaged, the entire probe and cable assembly must be replaced to maintain impedance standards.

• Does the probe require maintenance?

  The unit is a sealed, solid-state assembly. Periodic inspections should focus on the integrity of the cable jacket and the cleanliness of the connector pins.

• Why is the gap voltage verification necessary?

  Gap voltage verification ensures the probe is operating within the linear portion of its output curve, guaranteeing accurate vibration and position data.
