Eddy-Current Probe Scaling & Rotor Dynamics

The 11 mm transducer architecture delivers an expanded linear operational span tailored for larger industrial machinery journal and thrust applications. Output scaling maintains a steady linear sensitivity of 3.94 mV/um across the operating displacement window. During system alignment, static gap voltage validation must confirm a nominal -10 VDC baseline at mid-stroke position to avoid signal clipping during transient vibration events. Coaxial cross-talk suppression requires strict physical separation and proper shielding across multi-channel monitor racks.

Standard Delivery Scope

• 1 x 3300 XL 11 mm Proximity Probe Assembly with 1.0 m Coaxial Cable
• 1 x Mounting Locknut Assembly
• 1 x Fluorocarbon Protective Terminal Cap

Mechanical Installation and Routing Guidelines

• Clearance Verification: Ensure a minimum radial air gap clearance from surrounding structural metals to eliminate parasitic eddy-current damping.
• Thread Engagement: Apply standard industrial thread torque parameters when threading the probe housing into machine casing mounting ports.
• Cable Protection: Route the integrated coaxial lead through dedicated metal conduit, keeping absolute physical separation from power feeds.
• Connector Security: Fasten the ClickLoc coaxial connector securely until fully seated to prevent mechanical decoupling from continuous vibration.

Frequently Asked Questions and Technical Responses

• What is the calibrated output scale factor for this 11 mm transducer model?

  The nominal output scale factor is 3.94 mV/um when paired with an approved 3300 XL 11 mm Proximitor sensor.

• Can an 11 mm probe be connected to a standard 8 mm proximitor driver?

  No, 11 mm transducer components require matched 11 mm electronic drivers to preserve correct signal scaling and impedance.

• What is the continuous temperature tolerance rating of the probe tip?

  The tip assembly is rated for continuous thermal operation between -51 deg C and +177 deg C.

• How is the static gap voltage verified during system commissioning?

  A high-impedance voltmeter is connected to the monitor channel terminals to confirm the -10 VDC baseline.

• What target material alloy is required for accurate displacement calibration?

  Factory scaling assumes a standard AISI 4140 carbon steel shaft surface; alternative alloys require specific correction factors.

• What is the primary cause of signal degradation during continuous operation?

  Moisture infiltration inside the coaxial connector or mechanical abrasion of the outer fluorocarbon insulation layer.

• Why is an unthreaded casing length specified on certain mounting variants?

  The unthreaded section allows precise depth positioning through mounting brackets and sleeve adapters without thread binding.

• Can extension cables be added to the 1.0 meter integrated cable assembly?

  Yes, matching 11 mm extension cables can be integrated to achieve the desired total system electrical length.
