Rotor Dynamics & Gap Voltage Validation

The 3300 NSv extension cable delivers raw radio-frequency signals across its 75 ohm coaxial conductor structure to preserve precise loop tuning in compact machinery installations. Maintaining nominal capacitance (69.9 pF/m typical) is required for accurate eddy-current probe scaling and rotor dynamics monitoring. Field commissioning protocols require performing gap voltage validation at the Proximitor output terminals, adjusting physical probe position until achieving a baseline target of -10 VDC under non-rotating shaft conditions before dynamic signal processing.

Frequently Asked Questions

Q: What functionality do the connector protectors in Option 03 provide?

A: Option 03 includes elastomeric connector protectors that cover the ClickLoc coaxial junctions, preventing moisture, dust, and oil ingress at the probe-to-extension cable interface.

Q: Why is it critical to preserve the exact 4.5-meter physical length of the extension cable?

A: The total electrical capacitance of the 3300 NSv transducer system is calibrated to specific cable length combinations. Cutting, splicing, or changing the cable length degrades measurement linearity and sensitivity.

Field Installation Guidelines

Conduit Placement: Lay the unarmored FEP insulated coaxial cable inside metal conduit or dedicated instrument trays, isolating it from high-voltage AC lines.
Connector Protection: Slide the supplied connector protectors over the ClickLoc coaxial terminals prior to mating, ensuring a tight seal against ambient environmental contaminants.
Minimum Bend Radius: Maintain standard coaxial bend radius limits during installation to prevent deformation of the FEP dielectric core and shield integrity.
Shield Grounding: Verify overall shield continuity along the 4.5-meter run, maintaining single-point termination at the monitoring cabinet ground bar to mitigate ground loop currents.
