The Bently Nevada 330730-080-12-05 represents a premium solution for machinery vibration monitoring systems. Specifically, this 3300 XL 11 mm extension cable connects the proximity probe to the Proximitor Sensor over an 8.0-meter (26.2 feet) distance. Furthermore, it incorporates the FluidLoc cable option, which effectively prevents oil and other liquids from escaping through the cable interior. Meanwhile, the included connector protector adds crucial defense against humidity and moisture. Consequently, this model stands out as the ideal choice for critical turbomachinery where reliability and environmental protection are paramount.
The 330730-080-12-05 delivers consistent electrical performance for accurate data acquisition. For instance, its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft), maintaining signal integrity across the 8.0-meter length. Additionally, the DC resistance from the center conductor to the center conductor is rated at 2.0 ± 0.5 ohms, while the resistance from the coaxial conductor to the coaxial conductor sits at 0.6 ± 0.2 ohms.
Moreover, this cable utilizes 75 Ω triaxial construction with fluoroethylene propylene (FEP) insulation. The connector material features gold-plated brass with ClickLoc technology, which locks connections securely in place to prevent loosening from vibration. Finally, the system supports field wiring from 0.2 to 1.5 mm² (16 to 24 AWG), with a maximum extension length of 305 meters between the Proximitor Sensor and the monitor.
The Bently Nevada 330730-080-12-05 distinguishes itself through advanced sealing technologies. Firstly, the FluidLoc option creates a barrier that stops oil and process liquids from migrating through the cable core. This feature proves essential in turbine and compressor applications where fluid leakage poses safety and operational risks. Additionally, the connector protector supplies an extra layer of defense against humid or moist conditions. Bently Nevada actually recommends connector protectors for all installations, as they significantly increase environmental protection. However, silicone tape is provided as an alternative, though it should never be used in turbine oil environments.
Engineered for extreme conditions, the 330730-080-12-05 operates reliably across a wide temperature range. Specifically, its operating and storage temperature spans from -51°C to +177°C (-60°F to +351°F). The cable material consists of 75 Ω triaxial FEP insulation, while the optional armor utilizes flexible AISI 302 SST with an FEP outer jacket. Furthermore, the armored version weighs 140 g/m (1.5 oz/ft), totaling approximately 0.72 kg for the full 8.0-meter length.
Regarding mechanical durability, the tensile strength is rated at 330 N (75 pounds) for the probe case and 270 N (60 pounds) at the connectors. The probe case itself is constructed from AISI 304 stainless steel, and the probe tip uses polyphenylene sulfide (PPS) for wear resistance. Additionally, the patented TipLoc and CableLoc designs ensure robust bonding between components.
Proper installation of the 330730-080-12-05 ensures optimal system performance. Initially, power down the monitoring system before making any connections. Next, verify that the total system length (probe plus extension cable) matches your application requirements. Meanwhile, ensure the ClickLoc connectors are fully engaged until they lock into place, preventing accidental disconnection.
Furthermore, this cable works with various probe thread configurations, including ½-20, ⅝-18, M14 X 1.5, and M16 X 1.5 options. The linear range begins at approximately 0.5 mm from the target, spanning from 0.5 to 4.5 mm. Consequently, the recommended gap setting remains 2.5 mm (100 mils). For installations involving zener barriers, note that the extended DSL range is not applicable.
The 330730-080-12-05 carries the "05" agency approval option, indicating multiple certifications for global use. This compliance simplifies procurement for international projects, as it meets various regional safety and performance standards. Furthermore, the Proximitor Sensors are factory-calibrated to AISI 4140 steel by default, though calibration to other target materials remains available upon request.
