Physical & Electrical Specifications

Gap Voltage Validation and Rotor Dynamics

The eddy-current probe scaling provides a standardized 7.87 V/mm (200 mV/mil) output when paired with a matching 3300 XL Proximitor Sensor and extension cable. Mechanical installation requires precise gap voltage validation targeting -10 VDC at the center of the linear operating range to accurately measure dynamic shaft displacement and thermal position shifts. Advanced coil design minimizes cross-talk suppression issues when mounting adjacent probes on turbomachinery rotor dynamics monitoring installations.

Package Contents

• 1 x Bently Nevada 330101-00-47-05-02-05 3300 XL 8 mm Proximity Probe

Mechanical Installation Details

• Mounting Torque: Tighten the 3/8-24 UNF threaded probe case to a maximum torque of 8.5 N-m (75 in-lbf) during installation into bearing housings.
• Gap Adjustment: Set the physical gap using a feeler gauge or by monitoring gap voltage until the output reaches -10 VDC target bias voltage.
• Cable Routing: Maintain minimum bend radius of 25.4 mm (1.0 in) for standard coaxial cables to prevent internal conductor damage.
• Connector Protection: Ensure ClickLoc connectors are fully locked and dry; use connector protectors to prevent oil penetration and contamination.

Dispatch Logistics

• Delivery time: 3-5 days when payment finish.
• Dispatched via DHL, FEDEX, or UPS express service.
• Packaged in anti-static industrial packaging with high-density protective foam to withstand mechanical impact during transit.

Frequently Asked Questions

Q: What is the correct target gap voltage during physical installation?

A: Set the probe gap to achieve -10 VDC output at the Proximitor Sensor terminal, corresponding to the midpoint of the 2.0 mm (80 mils) linear range for AISI 4140 steel.

Q: Can this probe cable be shortened or lengthened in the field?

A: No. Altering the cable length changes the overall system capacitance and severely degrades eddy-current probe scaling and calibration accuracy.

Q: How does the ClickLoc connector prevent accidental loosening?

A: The ClickLoc coaxial connector features a self-locking mechanism that requires explicit axial tension to unlock, preventing detachment caused by rotor dynamics and vibration.

Q: What is the operating temperature rating for the probe tip?

A: The 3300 XL 8 mm probe tip and cable assembly operate continuously across a temperature range of -51 deg C to +177 deg C.
