Bently Nevada 330930-040-05-05 3300 NSv Extension Cable

Description

Option 040 (4.0 m cable length) and Option 05 (with stainless steel armor, without FEP jacket, and with connector protector) specify this 330930-040-05-05 3300 NSv Extension Cable configuration.

Unlike variants without mechanical protection or those featuring FEP jackets, this cable utilizes an uncoated stainless steel armor wrap that shields the inner coaxial wire from physical wear and high-vibration stresses in tight-clearance environments. Pre-installed connector protectors on the female ClickLoc end defend the critical probe connection from moisture and industrial fluids. Option 05 agency approvals allow installation in certified hazardous locations.

Features

• Option 040 specifies a total cable length of 4.0 meters (13.1 feet).
• Option 05 includes a protective uncoated stainless steel outer armor.
• Fluorosilicone connector protector pre-installed on the female coaxial termination.
• Option 05 agency approval package supports installations in multiple hazardous environments.
• Coaxial construction features gold-plated brass ClickLoc connectors.
• 25.4 mm (1.0 in) minimum bend radius allows routing through narrow conduits.

Applications

Used in the following industrial scenarios:

• Shaft vibration and axial position monitoring on high-speed rotating machinery.
• Aeroderivative gas turbines and compact radial compressors.
• Limited target geometries and small-bore applications using 3300 XL NSv proximity sensors.

Installation Guidelines

• Keep a minimum bend radius of 25.4 mm (1.0 in) along all routing paths to prevent physical distortion of the internal coaxial geometry.
• Tighten the gold-plated brass ClickLoc connectors finger-tight, or apply a connector-to-connector torque up to 0.56 N m (5 in lb) to secure the threaded connection.
• Ensure the female-end fluorosilicone connector protector is seated correctly over the probe connection to keep process contaminants from degrading electrical signals.
• Verify that the total length of the 3300 NSv probe combined with this 4.0-meter extension cable matches the calibrated target length (e.g., 5.0 m) of the associated 3300 XL NSv Proximitor Sensor.
