Description Reviews

The Bently Nevada 330730-080-02-00, also cataloged as the 330730 Extension Cable, operates as a dedicated hardware component for high-frequency signal transmission between proximity probes and Proximitor sensors within 3500 Machinery Protection System networks. It conducts high-frequency excitation signals while returning raw AC dynamic vibration and DC gap voltage readings across the physical transducer interface without signal attenuation.

Gap Voltage Validation and Signal Integrity

The 330730-080-02-00 extension cable maintains a tight 69.9 pF/m capacitance tolerance to preserve linear eddy-current probe scaling (3.94 V/mm or 100 mV/mil output response) across the entire dynamic range. Deviations in physical cable capacitance directly shift the LC resonant circuit frequency of the 3300 XL Proximitor sensor, introducing measurement errors into rotor dynamics tracking and phase angle calculations.

During field commissioning, gap voltage validation targets a nominal -10 VDC reading at the Proximitor output terminals when the probe rests at mid-span mechanical clearance. The integrated connector protectors under option 02 insulate the ClickLock miniature coaxial interface from liquid ingress and environmental contamination, ensuring consistent cross-talk suppression in high-density cable trays.

Frequently Asked Questions

Q: Can the 330730-080-02-00 extension cable be cut or modified in the field if 8.0 m is longer than required?

A: No. Altering the cable length changes the total system electrical capacitance and resistance, which invalidates the factory calibration curve of the Proximitor sensor and introduces significant scale factor errors into displacement and vibration measurements.

Q: What specific function do the connector protectors serve on the 02 cable option?

A: The connector protectors provide a rubberized physical boot over the miniature coaxial connections. This prevents conductive moisture, oil, and dust from entering the male/female pin interface, eliminating high-resistance leakage paths that alter gap bias voltage readings.

Field Installation Guidelines

Inspect the FEP insulation jacket, coaxial connectors, and rubber connector boots for mechanical cuts, contamination, or pin damage before routing.
Route the cable through dedicated electrical conduits or metal trays, maintaining a minimum static bend radius of 25.4 mm (1.0 in) along the run.
Keep the cable isolated from high-voltage AC motor lines and variable frequency drive (VFD) power cables by a minimum distance of 300 mm to prevent inductive noise coupling.
Align the coaxial ClickLock connectors, press firmly until fully seated, and secure finger-tight plus 1/8 turn. Slide the connector protector boot over the joined mating junction.
Perform gap voltage validation across the Proximitor sensor signal output terminals using a digital multimeter; confirm the bias voltage reads approximately -10.0 VDC when the machine shaft is centered.
Connect the cable shield exclusively to the designated instrument earth at the Proximitor enclosure end. Leave the cable shield floating at the probe connection end to prevent ground loop currents.
