The Bently Nevada 330930-045-00-00, also cataloged as the 330930 Extension Cable, operates as a dedicated hardware component for signal transmission between proximity probes and Proximitor sensors within 3300 NSv Transducer System platforms.

Hardware Specifications

Eddy-Current Signal Integrity and Transmission

The 330930 extension cable maintains the critical impedance matching required for eddy-current probe scaling in 3300 NSv applications. Because the 3300 NSv system operates at specific resonant frequencies tailored for small-target sensitivity, this cable is factory-matched to ensure that the total loop inductance and capacitance remain within specified limits. Proper cable routing is required to prevent external electromagnetic noise from impacting gap voltage validation (-10 VDC targets). Maintaining the integrity of the coaxial shield is necessary for cross-talk suppression, ensuring that the modulated RF signal from the probe reaches the Proximitor interface without phase distortion or attenuation.

Technical Query Resolution

Q: Can this 4.5-meter extension cable be used with standard 3300 XL 8 mm probes?

A: No. The 3300 NSv system utilizes distinct electrical tuning parameters compared to 3300 XL series components. Using non-compatible cables will alter the probe sensitivity and invalidate the system calibration.

Q: Does this cable provide electrical isolation between the probe and the Proximitor?

A: No. This is a passive coaxial extension. While the connectors provide physical protection, they do not provide galvanic isolation.

Q: Is it permissible to shorten or extend this cable in the field?

A: Field modifications to the cable length are prohibited. The transducer system is calibrated as a complete loop (probe, extension cable, and Proximitor); changing the cable length alters the electrical characteristics and causes measurement errors.

Field Installation Guidelines

• Inspect the coaxial cable and connectors for signs of damage, moisture, or metallic debris before installation.
• Ensure the path from the machine case to the junction box allows for the cable to be installed without exceeding the minimum bend radius.
• Clean the ClickLoc connectors with a lint-free cloth to ensure positive electrical contact.
• Align the keyways on the ClickLoc connectors and rotate the collar until a positive click is felt, indicating proper engagement.
• Secure the cable using cable ties or conduit clamps at regular intervals to prevent mechanical vibration wear.
• Verify the total loop electrical signature once installed to ensure the gap voltage remains stable and within operational limits.
