Description

Option 045 (4.5 meters length) and Option 00 (without stainless steel armor) specify this 3300 NSv extension cable configuration — 330930-045-00-CN, featuring the -CN China hazardous area approval package.

This 3300 NSv extension cable provides electrical connection between a 3300 NSv proximity probe and a 3300 XL NSv Proximitor Sensor. It is used in systems where target area or physical clearances are constrained, such as in aeroderivative gas turbines, centrifugal compressors, and small-bore rotating machinery. The unarmored coaxial construction maintains a nominal 75 ohm impedance, enabling transmission of high-frequency eddy-current displacement signals without distortion.

Features

Option 045 provides a nominal cable length of 4.5 meters (14.8 feet) to match specific system requirements.
Option 00 specifies an unarmored coaxial cable configuration, optimizing routing flexibility in protected conduits.
Suffix -CN provides certified compliance with China hazardous area standard approval packages including NEPSI and CCC markings.
Gold-plated brass ClickLoc coaxial connectors resist loosening and maintain electrical contact.
Standard FEP cable jacket provides chemical resistance and operational stability in industrial environments.

Applications

Radial vibration and axial position measurements on rotating machinery with tight clearances.
Aeroderivative gas turbines, small steam turbines, and turbochargers.
Fluid-film bearing monitoring in small-bore industrial pumps and centrifugal compressors.
Use in hazardous areas requiring NEPSI or CCC certification packages in China.

Installation Guidelines

Observe the following engineering practices during installation of the extension cable:

Verify that the total length of the extension cable plus the probe length matches the calibrated system length of the Proximitor Sensor (typically 5.0 meters or 7.0 meters).
Ensure the minimum bend radius of 25.4 mm (1.0 in) is maintained at all points to prevent coaxial layer deformation.
Use silicone self-fusing tape (Bently Nevada part number 03200006) or connector protector kits on probe-to-extension cable connections to prevent turbine oil or process fluids from penetrating the ClickLoc connectors.
Do not exceed the maximum connector torque of 0.56 N m (5 in lb); connectors are designed to lock securely when hand-tightened.
Route the cable through dedicated, grounded metal conduits or cable trays to minimize electromagnetic interference from adjacent high-voltage machinery.

Compliance and Certifications

NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation) certification for hazardous locations in China.
CCC (China Compulsory Certification) marking for explosion-proof safety standards.
ATEX/IECEx intrinsically safe approvals when connected to appropriate barriers or isolators as specified in Bently Nevada drawing 141092.

FAQ

What does the -CN suffix represent on this extension cable?

The -CN suffix indicates that this cable is certified under the China hazardous area approval package, including NEPSI and CCC certifications, making it compliant for explosion-proof applications in China.

What is the length of the 330930-045-00-CN cable?

The cable has a nominal length of 4.5 meters (14.8 feet). It must be paired with a compatible 3300 NSv probe to achieve the correct system length.

Is this extension cable armored?

No. The -00 option in the SKU designates that the cable is unarmored (without stainless steel armor), which offers greater routing flexibility in protected conduits.

What system is this extension cable compatible with?

It is compatible with the 3300 XL NSv Proximity Transducer System, specifically pairing with a 3300 NSv proximity probe and a 3300 XL NSv Proximitor Sensor.
