Bently Nevada 330930-060-02-05 3300 NSv Extension Cable

Description

330930-060-02-05 specifies this 3300 NSv extension cable configured with a 6.0-meter length, stainless steel armor protection without an FEP jacket, and multiple international hazardous area agency approvals. This option combination utilizes robust stainless steel armoring to protect the internal 75-ohm coaxial cable from abrasive wear, mechanical crushing, and environmental impacts while omitting the outer fluoropolymer sheath for installations where extra chemical-washdown protection is unnecessary.

Operating as an intermediate link within the 3300 XL NSv Proximity Transducer System, the cable maintains electrical and mechanical compatibility with Bently Nevada 3300 NSv proximity probes and 330980 Proximitor sensors. The system is optimized for machinery vibration and shaft position measurements in applications with tight target geometries or restricted clearance, such as small-bore rotating equipment and aeroderivative gas turbines.

Features

• 6.0-meter (19.7 feet) cable length matching specific calibrated system length configurations.
• Stainless steel armor protection (without outer FEP jacket) shielding the inner coaxial line from physical damage and severe industrial wear.
• Agency Approval Option 05 specifying multiple hazardous area certifications, including CSA, ATEX, and IECEx.
• Gold-plated brass ClickLoc coaxial connectors providing self-locking mechanics to prevent loosening during operation.
• 75-ohm characteristic impedance designed to maintain stable signal transmission without attenuation.
• Patented CableLoc design compatibility withstanding high pulling forces up to 220 N (50 lb) at standard interfaces.

Applications

• Vibration and axial position monitoring in high-speed, small-bore turbocompressors.
• Aeroderivative gas turbines and compact rotating machines with limited target geometries.
• Industrial gearboxes, pumps, and centrifuges requiring mechanical armoring against external physical hazards.
• Hazardous-area installations requiring intrinsically safe or non-incendive transducer loops.

Installation Guidelines

To maintain correct sensor system calibration, the combined length of the proximity probe and this extension cable must match the calibrated total length of the compatible Proximitor sensor (for example, pairing a 1.0-meter probe with this 6.0-meter extension cable to complete a 7.0-meter system). Ensure a minimum bend radius of 25.4 mm (1.0 in) is maintained along the entire cable path. Connectors must be mated finger-tight, with a maximum allowable connector-to-connector torque of 0.56 Nm (5 in lb). The use of silicone self-fusing tape or a connector protector kit is recommended to prevent fluid ingress at mated joints; however, silicone tape should not be used inside a machinery casing exposed to turbine oil.
