Installation & Setup
When installing the Bently Nevada 330730-040-02-CN extension cable, ensure proper connection to the 3300 XL probe and Proximitor sensor. The cable comes with a connector protector for enhanced environmental protection, especially in humid or moist conditions. For installations exposed to turbine oil, use the provided silicone tape instead of connector protectors to prevent oil wicking. Recommended field wiring: 0.2 to 1.5 mm² (16–24 AWG) using three-conductor shielded triad cable, with maximum distance of 305 meters (1,000 feet) between Proximitor and monitor.
Maintenance & Reliability
Regular inspection of the Bently Nevada 330730-040-02-CN cable connectors is recommended to ensure integrity. The gold-plated brass connectors resist corrosion, while the optional flexible AISI 302 SST armor extends service life in abrasive environments. The cable’s FEP jacket withstands extreme temperatures from -52°C to +177°C, reducing replacement frequency. For maximum reliability, avoid exceeding the tensile strength rating of 330 N (75 lbs) at the probe case to probe lead.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330730-040-02-CN, verify that your system requires a 4.0-meter extension cable with the standard connector protector. This cable is part of the 3300 XL series and is compatible with all 3300 XL probes and Proximitor sensors. For armored versions, specify the optional armor.
