Bently Nevada 330930-040-04-CN 3300 NSv Extension Cable

Description

Option 040 (4.0 m cable length) and Option 04 (with stainless steel armor, FEP jacket, and connector protector) specify this 3300 XL NSv extension cable configuration — 330930-040-04-CN.

The 330930-040-04-CN 3300 NSv Extension Cable is used within the 3300 XL NSv Proximity Transducer System to transfer non-contact eddy-current displacement signals from the probe to the 330980 Proximitor sensor. This cable serves in small-bore machinery, aeroderivative gas turbines, and high-speed equipment with limited target geometry. This variant incorporates a stainless steel armor sheath with an outer FEP jacket, protecting the coaxial conductor from abrasive mechanical wear and process chemical exposure. In addition to gold-plated brass ClickLoc connectors, it is equipped with a fluorosilicone connector protector on the female end and conforms to Chinese safety standards via NEPSI and CCC certifications.

Features

• Cable Length: 4.0 meters (13.1 feet) total length configuration.
• Protective Sheathing: Stainless steel armor with an outer FEP (Fluorinated Ethylene Propylene) jacket to resist abrasion and process chemicals.
• Moisture Exclusion: Pre-installed fluorosilicone connector protector seals the gold-plated brass ClickLoc connections from liquid ingress.
• Secure Locking: ClickLoc miniature coaxial connectors lock securely into position to prevent unintended loosening.
• Chinese Market Compliance: Configured with NEPSI and CCC approvals for hazardous area operations.
• System Interchangeability: Fully compatible with previous-generation 3300 RAM proximity systems.

Applications

Typical machinery applications include:

• Vibration and axial position monitoring in small-bore machinery.
• Aeroderivative gas turbine installations with tight clearances.
• High-speed centrifugal compressors and pumps with limited target geometry.
• Industrial sites requiring localized Chinese hazardous area certifications (NEPSI and CCC).

Installation Guidelines

• Mount the cable maintaining a minimum bend radius of 25.4 mm (1.0 in) to prevent internal coaxial conductor damage.
• Ensure the female ClickLoc connector is securely mated to the proximity probe's male connector and tighten to finger-tight, or a maximum of 0.56 Nm (5 in-lb) of torque.
• For maximum moisture protection, ensure the pre-installed connector protectors or recommended silicone self-fusing tape are properly installed over the connection.
• Keep the cable routed away from high-voltage conduit and potential physical pinch points. Maintain proper grounding by connecting the shield at the Proximitor Sensor end only.
