Bently Nevada 330930-065-05-05 3300 NSv Extension Cable

Description

Option 065 specifies a 6.5-meter cable length, while Option 05 designates a stainless steel armored construction without an outer FEP jacket and equipped with a connector protector for this 3300 NSv extension cable — 330930-065-05-05. Used as a link within the 3300 XL NSv proximity transducer system, this 3300 NSv extension cable maintains the electrical integrity of non-contact displacement measurements on rotating machinery where target areas are reduced or clearance constraints are tight.

Unlike unarmored configurations such as option 00 or 03, this cable features robust stainless steel armor to shield the internal coaxial line from physical damage, crushing, and cuts in challenging industrial environments. The integration of a fluorosilicone connector protector on the female connector end prevents oil, moisture, and chemical penetration into the ClickLoc coupling, preventing signal degradation in severe machine environments. Option 05 agency approval designates multiple hazard location certifications.

Features

• Cable length option 065 provides 6.5 meters (21.3 feet) of extension to match total system length requirements.
• Option 05 mechanical construction includes stainless steel armor for physical protection without an outer FEP jacket, plus a pre-installed fluorosilicone connector protector.
• Gold-plated brass ClickLoc coaxial connectors ensure secure interlocking and steady signal path resistance.
• Agency approval option 05 provides multiple approvals (including CSA, ATEX, and IECEx) for hazardous locations.
• Electrical design matches 75 ohm system impedance for signal preservation over the entire transducer loop.

Applications

The 3300 NSv system is used in environments with limited target geometries and tight clearances. Common industrial installations include:

• Radial vibration and axial position measurements on small-bore machinery.
• Vibration monitoring on aeroderivative gas turbines.
• High-speed centrifugal compressors and turbocompressors.
• Fluid-film bearing machinery with narrow probe mounting corridors.

Installation Guidelines

Proper installation of the 3300 NSv extension cable is necessary for signal integrity. The following rules must be observed:

• Maintain the minimum bend radius of 25.4 mm (1.0 in) along the entire armored run to prevent inner core damage.
• Avoid over-torqueing the ClickLoc connection; connectors should be finger-tightened, with a maximum torque of 0.56 Nm (5 in-lb).
• Ensure the combined length of the proximity probe lead and extension cable matches the calibrated system length of the 3300 XL NSv Proximitor Sensor (typically 5.0 meters or 7.0 meters).
• Use the pre-installed fluorosilicone connector protector on the female coaxial end to shield the coupling from process fluids, dirt, and electrical grounding issues.
• Isolate the cable run from adjacent high-voltage lines to reduce electromagnetic interference.
