Technical Parameter Specifications

Eddy-Current Probe Scaling & Rotor Dynamics

The transducer utilizes high-frequency radio frequency signals to measure the static and dynamic distance between the probe tip and the observed conductive target surface. Signal scaling is calibrated to deliver a linear output response of 7.87 mV/um across the designated measurement range. Gap voltage validation must maintain a nominal -10 VDC operational target when the probe is set at mid-range position relative to the rotating shaft to prevent signal clipping and distortion during transient machinery events.

Delivery Scope & Kit Contents

• 1 x 3300 XL 8 mm Proximity Probe Tip Assembly
• 1 x Metric Mounting Thread Adapter Nut
• 1 x Fluorowrap Protective Terminal Cap

Physical Installation & Cabling Guidelines

• Route extension cables away from high-voltage power conduits to minimize electromagnetic interference on the high-frequency modulated signal.
• Ensure probe tip mounting maintains a minimum radial clearance of 10 mm from surrounding structural metals to prevent erroneous scaling offsets.
• Torque the mounting threads according to standardized industrial thread engagement limits without exceeding mechanical threshold limits.
• Utilize dedicated grounding shields on the interconnecting coaxial cabling to preserve signal integrity across long transmission runs.

Operational Inquiry and Technical FAQ

• What is the nominal output scale factor for this probe model?

  The nominal output scale factor is 7.87 mV/um when paired with a standard 3300 XL Proximitor sensor.

• Does this configuration support hazardous area installations?

  Yes, the agency approval option supports certified hazardous location applications according to regional directives.

• What is the allowable operating temperature range at the probe tip?

  The probe tip can operate continuously in thermal environments ranging from -51 deg C to +177 deg C.

• How is the gap voltage verified during commissioning?

  A digital voltmeter is connected across the Proximitor monitor output terminals to verify the static -10 VDC target.

• Can this probe be used with non-standard extension cables?

  No, system calibration requires matching the exact electrical length designation specified by the catalog ordering code.

• What thread configuration is supplied with this specific part number?

  The unit features standard metric thread sizing corresponding to the designated model option matrix.

• Is calibration drift affected by target material composition?

  Yes, output scaling assumes standard AISI 4140 steel targets; different alloys require specific calibration correction factors.

• What is the primary failure mode associated with improper installation?

  Mechanical fatigue resulting from excessive tightening torque or abrasive rubbing against the rotating shaft surface.
