Bently Nevada 330130-045-01-CN 3300 XL Standard Armored Extension Cable

Description

330130-045-01-CN specifies a 3300 XL Standard Extension Cable configuration featuring a 4.5 m (14.8 ft) cable length, protective stainless steel armor (Option 01), and the -CN China hazardous area approval package. This configuration utilizes an FEP-insulated 75-ohm coaxial cable wrapped inside a flexible stainless steel armor jacket for high physical durability against abrasion and mechanical stress. The cable has gold-plated miniature ClickLoc coaxial connectors on both ends to maintain solid electric coupling within the transducer system.

This extension cable connects a 3300 XL 8 mm proximity probe to a 3300 XL Proximitor Sensor. Together, they form a complete eddy-current proximity transducer system that measures shaft vibration, position, and speed on high-speed rotating machinery. The -CN suffix certifies this cable for installation in hazardous areas within China, satisfying national NEPSI and CCC explosion-proof standards.

Features

• Option 045 defines a total cable length of 4.5 meters (14.8 feet) to match 5-meter or 9-meter system total lengths.
• Option 01 provides standard stainless steel protective armor wrap without a connector protector.
• FEP insulation jacket provides outstanding resistance to chemicals, petroleum fluids, and extreme environmental elements.
• Operates across a wide temperature range of -52 degC to +177 degC.
• Equipped with premium gold-plated coaxial ClickLoc connectors for stable high-frequency signal transmission.
• -CN suffix guarantees compliance with Chinese hazardous area regulatory frameworks (NEPSI and CCC approvals).

Applications

This extension cable is used in machinery protection systems across heavy industries. Typical installations include:

• Vibration and axial position monitoring on steam and gas turbines
• Centrifugal compressors, pumps, and industrial fans
• Hydroelectric and thermal power generation machinery
• Petrochemical, refinery, and pipeline rotating assets
• Industrial gearboxes and electric motors

Installation Guidelines

• Connector Torque: Connectors should be tightened finger-tight. If mating to a non-XL stainless steel connector, finger-tighten and use pliers to apply an additional 1/8 turn.
• Bend Radius: Observe a minimum physical bend radius of 25.4 mm (1.0 in) for the armored cable to avoid damaging the internal coaxial core.
• Protective Conduit: Run cables through secondary conduit systems in harsh mechanical areas to reduce the risk of mechanical severance.
• Moisture Protection: Apply silicone self-fusing tape or install connector protectors when operating in wet or high-humidity environments external to the machine casing.

Compliance and Certifications

The 330130-045-01-CN extension cable is approved for hazardous and industrial environments with the following standard listings:
