Bently Nevada 330930-060-00-CN 3300 NSv Extension Cable

Description

Option 060 (6.0 m cable length) and Option 00 (without stainless steel armor) specify this 3300 NSv extension cable configuration — 330930-060-00-CN.

This unarmored coaxial cable connects a 3300 NSv proximity probe to a 330980 Proximitor sensor in non-contact eddy-current displacement measurement loops. The -CN suffix indicates compliance with the China hazardous area approval package, certifying the assembly under NEPSI and CCC regulations for use in classified industrial zones.

Features

• Option 060 cable length provides a 6.0-meter (19.7 feet) physical extension.
• Option 00 specifies a standard unarmored configuration, suitable for installations utilizing protective conduits.
• Standard 75-ohm coaxial design maintains signal impedance and limits transmission loss.
• Equipped with miniature coaxial ClickLoc connectors at both ends for reliable plug-and-play connections.
• Suffix -CN delivers NEPSI and CCC China hazardous area approval compliance.

Applications

This extension cable is used in systems monitoring small-bore machinery, aeroderivative gas turbines, and high-speed industrial equipment with limited target geometry. Typical industrial sectors include:

• Power generation turbine systems
• Petrochemical and oil and gas processing facilities
• Centrifugal and axial compressor monitoring
• High-speed rotating machinery with tight target constraints

Installation Guidelines

• Maintain a minimum bend radius of 25.4 mm (1.0 in) during routing to prevent core or shield damage.
• Ensure the total electrical length of the probe and extension cable matches the calibrated length of the 3300 XL NSv Proximitor Sensor (e.g., 5.0 m or 7.0 m system length).
• Protect connectors from ingress of moisture, turbine oil, and other contaminants by utilizing connector protectors or silicone self-fusing tape (such as part number 03200006) on the connections.
• Route cables through conduit where mechanical protection is required, since this configuration (Option 00) does not feature stainless steel armor.

Compliance and Certifications

• CCC (China Compulsory Certification)
• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation)
• ATEX/IECEx (Intrinsically safe Ex ia IIC, non-sparking Ex nA/ec IIC)
• CE Directive compliance (EMC 2014/30/EU, RoHS 2011/65/EU)
• SIL 2 / SIL 3 functional safety rated
