Electrical characteristics are critical for signal integrity. The center conductor has a DC resistance of 0.220 Ω/m (0.067 Ω/ft), while the shield measures 0.066 Ω/m (0.020 Ω/ft). Cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. These parameters ensure minimal signal loss over the specified length.
Installation & Setup Guidance
Proper installation is essential for accurate readings. Ensure that the extension cable length and the probe length, when added together, equal the Proximitor Sensor total length. This ensures correct system calibration.
For field wiring, use a three-conductor shielded triad cable with a cross-section of 0.2 to 1.5 mm² (16 to 24 AWG). If using ferrules, 0.25 to 0.75 mm² (18 to 23 AWG) is recommended. The maximum length between the 3300 XL NSv Proximitor Sensor and the monitor is 305 meters (1,000 feet). Be aware that longer wiring may cause signal rolloff at high frequencies; refer to the frequency response graphs (Figure 16 and Figure 17) in the manual.
The linear range of the system is 1.5 mm (60 mils), beginning at approximately 0.25 mm (10 mils) from the target. The recommended gap setting is 1.0 mm (40 mils).
Maintenance & Reliability
The stainless steel armor and FEP jacket protect the cable from mechanical damage and chemical exposure, enhancing long-term reliability. Gold-plated brass connectors resist corrosion and ensure stable electrical contact. The cable withstands tensile loads up to 220 N (50 lb) at the probe case, probe lead connectors, and stainless steel armor, reducing the risk of connection failure.
Routine inspection should focus on connector integrity and jacket condition. With proper care, this extension cable provides extended service life, minimizing replacement costs and downtime.
Compatibility & Integration
The 330930-040-01-05 is part of the Bently Nevada 3300 NSv system, designed for use with 3300 XL NSv Proximitor Sensors and compatible monitors. It integrates seamlessly into existing vibration monitoring setups, ensuring reliable data acquisition for predictive maintenance programs.
Selection Guide & Purchasing Advice
Before ordering, verify the required cable length and connector options for your specific application. Confirm that the extension cable length plus probe length matches the Proximitor Sensor total length.
