Eddy-Current Probe Impedance Scaling & Gap Voltage Validation

To achieve linear eddy-current probe scaling of 7.87 V/mm (200 mV/mil), the 330130-085-02-CN extension cable is manufactured with tight tolerances for characteristic impedance and capacitance. System calibration mandates that the total electrical length of the probe and extension cable equals exactly 9.0 meters. The Proximitor sensor converts physical proximity fluctuations into voltage outputs based on this matched circuit. Proper system integration preserves electrical parameters to guarantee accurate gap voltage validation, targeting a nominal -10 VDC baseline in the center of the linear calibration range. This signal integrity minimizes phase offset during high-speed rotor dynamics monitoring.

Frequently Asked Questions

Q: How does the CN suffix affect physical installation in hazardous locations?

A: The CN option indicates certified compliance with ATEX, IECEx, and Chinese NEPSI intrinsically safe standards. In these environments, the cable must be wired through certified intrinsic safety barriers or galvanic isolators matching the system electrical entity parameters.

Q: Can this 8.5-meter standard cable be modified or spliced in the field?

A: No. Splicing or cutting the coaxial cable changes the system capacitance and impedance. This permanently alters the calibration parameters of the 3300 XL Proximitor sensor, causing inaccurate vibration and position feedback.

Field Installation Guidelines

Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for standard coax installation.
Connector Torque: Hand-tighten coaxial connectors, then turn an additional 1/4 turn using insulated connector wrenches to prevent core degradation.
Shield Grounding: The coaxial shield must be grounded at only one point (typically at the Proximitor sensor terminal strip) to prevent ground loops.
