Eddy-Current Probe Scaling & Rotor Dynamics

The 330730 coaxial extension cable acts as a calibrated analog transmission pathway that preserves the exact impedance and capacitance ratings of the 3300 XL 11 mm transducer system. This precise impedance matching is required to maintain the default eddy-current probe scaling of 3.94 V/mm (100 mV/mil) when transmitting high-frequency signals back to the Proximitor sensor. To guarantee measurement accuracy under dynamic rotor dynamics, field engineers must perform gap voltage validation after inserting the cable, ensuring the quiescent sensor output aligns with the target -10 VDC baseline at the middle of the linear sensing envelope.

Frequently Asked Questions

Q: Can this 4.0-meter extension cable be combined with a 1.0-meter probe on a standard 5.0-meter Proximitor sensor?

A: Yes. The 4.0-meter cable length option combined with a 1.0-meter proximity probe creates a total physical electrical length of 5.0 meters, which matches the calibration tuning of a 5.0-meter 3300 XL 11 mm Proximitor sensor.

Q: Is this extension cable hot-swappable while the monitoring system is fully powered?

A: Yes. Disconnecting the coaxial ClickLoc connector while the associated Proximitor sensor is powered does not cause electrical damage, though it will trigger a channel under-voltage limit fault at the monitoring rack.

Field Installation Guidelines

Connector Splicing and Alterations: Do not cut, shorten, or splice this extension cable under any circumstances. Altering the physical length changes the electrical capacitance of the high-frequency coaxial circuit, permanently degrading the transducer scale factor calibration.
Miniature Coaxial Protection: Install a silicone connector protector sleeve over the ClickLoc junction. The coaxial connectors must remain entirely dry and clean to prevent signal loss and impedance drift.
Shield Isolation from Ground: Ensure the braided outer copper shield of the extension cable is physically isolated from local machine housings and conduits. The shield must terminate solely at the Proximitor sensor terminal block to prevent ground loops from degrading signal integrity.
