Hardware Specifications

Rotor Dynamics and Gap Voltage Validation

• The transducer system converts physical shaft displacement relative to the probe tip into an electrical output signal.
• Proper installation requires setting the static gap voltage to -10 VDC within the linear operating range.
• Eddy-current probe scaling ensures accurate dynamic vibration monitoring and radial position tracking for rotating machinery.
• Cross-talk suppression mechanisms prevent signal interference when multiple probes are installed in close proximity on the same bearing housing.

Package Contents

• 1 x 3300 XL 8 mm Proximity Probe
• 1 x Probe Mounting Nut
• 1 x Insulating Sleeve

Mechanical Installation Guidelines

• Mount the probe securely using standard 3/8-24 UNF threading into the machine housing or mounting bracket.
• Ensure the target surface meets the minimum diameter requirements of 25.4 mm to avoid boundary-effect measurement errors.
• Route the integral coaxial cable away from high-voltage power lines and variable frequency drives to minimize electromagnetic interference.
• Torque the mounting hardware according to manufacturer specifications to prevent mechanical loosening during continuous high-speed machinery operation.

Technical FAQ

• What is the nominal scale factor of this proximity transducer system?

  The incremental scale factor is calibrated to 7.87 V/mm over the linear measurement range.

• How is the initial static gap voltage set during calibration?

  The gap voltage must be adjusted to -10 VDC using a digital voltmeter connected to the Proximitor sensor output terminals.

• What is the operating temperature limit for the probe tip?

  The probe tip withstands continuous temperatures ranging from -35 deg C to +177 deg C.

• Can the integral coaxial cable be shortened or spliced?

  Field modification of the integral cable length alters the electrical resonance and invalidates system calibration.

• What thread size does this specific probe model utilize?

  This model utilizes a 3/8-24 UNF mounting thread without stainless steel armor protection.

• Does the probe require an external power supply directly?

  No, it receives excitation power through the connected 3300 XL Proximitor sensor unit.

• What is the maximum linear measuring range of the 8 mm probe?

  The linear measurement range spans 2.0 mm, positioned centrally along the operating characteristic curve.

• How should the coaxial shield be terminated to prevent ground loops?

  The shield should be grounded exclusively at the monitor or instrumentation rack end as per system guidelines.
