The Bently Nevada 330730-080-03-00 is a rugged extension cable engineered specifically for the 3300 XL 11 mm proximity probe system. Primarily, this 3300 XL extension cable serves as the vital interconnection between the probe and the Proximitor Sensor, enabling accurate vibration and position monitoring from a distance. Furthermore, its armored construction and connector protector offer superior protection against mechanical damage and environmental contaminants.
This 11 mm extension cable features a generous length of 8.0 metres (26.2 feet), providing ample reach for installations where the Proximitor Sensor must be positioned away from the measurement point. Additionally, the connector and cable option "03" denotes an armored cable design complete with a connector protector. Meanwhile, the cable construction utilizes a 75 Ω triaxial configuration with fluoroethylene propylene (FEP) insulation, which preserves signal integrity even across extended distances.
Superior protection distinguishes this cable from standard alternatives. For instance, the flexible AISI 302 stainless steel (SST) armor wraps around the cable, providing excellent resistance against crushing, abrasion, and mechanical impact. Moreover, the included connector protector offers additional defense against moisture and humidity, effectively preventing corrosion and signal degradation. Additionally, all connectors feature gold-plated brass construction, ensuring low contact resistance and outstanding long-term reliability.
The electrical parameters of this Bently Nevada extension cable are precisely controlled to maintain system accuracy. Specifically, the typical capacitance measures 69.9 pF/m (21.3 pF/ft), which is critical for proper Proximitor Sensor operation. Furthermore, the resistance from the center conductor to center conductor (RCORE) is 2.0 ± 0.5 ohms, while the resistance from the coaxial conductor to coaxial conductor (RJACKET) is 0.6 ± 0.2 ohms. Therefore, this 3300 XL series extension cable seamlessly integrates with the overall measurement chain without introducing significant signal loss.
This armored extension cable operates reliably across a broad temperature spectrum. To begin with, the operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, exposing the cable to temperatures consistently below -34°C (30°F) may compromise the pressure seal's longevity. Besides this thermal consideration, the FEP insulation provides excellent resistance to chemicals, moisture, and extreme temperatures, making it ideally suited for demanding industrial settings such as turbine decks and compressor stations.
Proper installation ensures optimal performance and extended service life. First, the ClickLoc connectors should be tightened finger-tight, with a maximum torque of 0.565 N•m (5 in•lb). Next, for field wiring between the Proximitor Sensor and the monitor, use three-conductor shielded triad cable ranging from 0.2 to 1.5 mm² (16 to 24 AWG). Finally, the maximum field wiring length is 305 meters (1,000 feet), though frequency response rolloff should be carefully considered at extended distances to maintain measurement accuracy.
The 3300 XL transducer system incorporates several ingenious design elements. For instance, the patented TipLoc molding method creates a robust bond between the probe tip and the probe body, enhancing mechanical integrity under vibration. Meanwhile, the CableLoc design securely attaches the probe cable, providing 330 N (75 lb) pull strength for added security. Additionally, silicone tape is supplied with each extension cable as an alternative to connector protectors. Nevertheless, this tape is not recommended for applications where the connection will be exposed to turbine oil, as the tape may degrade in such aggressive environments.
