Bently Nevada 330930-040-01-00 3300 NSv Extension Cable

Description

330930-040-01-00 is a 4.0-meter (13.1 feet) 3300 NSv Extension Cable specified with stainless steel armor and an outer FEP jacket (Option 01), without agency approvals (Option 00).

This cable interfaces between a 3300 NSv proximity probe and a 3300 XL NSv Proximitor Sensor. The addition of the FEP-jacketed stainless steel armor provides protection against physical wear, mechanical shear, and chemical exposure in demanding industrial environments, distinguishing it from standard unarmored configurations.

Features

• 4.0 meters (13.1 feet) overall cable length configuration (Option 040).
• Stainless steel protective armor with protective FEP jacket (Option 01).
• Gold-plated brass ClickLoc miniature coaxial connectors provide a secure, twist-locking connection.
• Designed to match 3300 NSv probe impedance and signal characteristics.
• FEP outer jacket resists oils, chemical solvents, and high humidity.

Applications

• Shaft vibration and position monitoring in narrow or restricted spaces.
• Small-bore turbomachinery and aeroderivative gas turbine installations.
• High-speed centrifugal compressors and pumps with limited target geometries.
• Industrial machinery where mechanical armor protection against hot oils and abrasion is necessary.

Installation Guidelines

Proper installation of the 3300 NSv extension cable ensures stable signal transmission and mechanical durability. Follow these engineering guidelines:

• Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) during routing to prevent internal conductor damage.
• Connector Protection: While this configuration does not include pre-installed connector protectors, it is recommended to use connector protectors or silicone self-fusing tape in wet or oil-exposed environments to prevent signal degradation. Do not use silicone tape inside the machine casing if exposed to turbine oil.
• Routing: Route cables away from high-voltage lines, AC motors, and other electromagnetic interference sources. Secure cables with appropriate mounting clips without over-tightening.
• Torque: Connect the probe-to-cable miniature ClickLoc connectors to finger tight, then apply a maximum recommended torque of 0.56 Nm (5 in-lb) using proper tools. Do not use pliers.
• Total Length Verification: Ensure that the combined length of the proximity probe and the extension cable matches the total calibrated length of the 3300 XL NSv Proximitor Sensor (typically 5.0 m or 7.0 m).
