Introduction
The model 330130-045-02-05 is a 4.5-Meter Extension Cable for Bently Nevada's 3300 NSv Proximity Transducer Systems. This is a critical passive component used to connect a proximity probe (transducer) to its corresponding proximitor (signal conditioner/demodulator) when they are located apart. The -045 suffix specifically denotes a cable length of 4.5 meters, while the -02-05 defines the connector types and a top-exit configuration. This cable is designed with robust shielding to protect the high-frequency, low-level signals from the probe against electromagnetic interference (EMI), ensuring signal integrity and maintaining the calibrated performance of the entire transducer system.
Parameters / Specifications
The following table outlines the key technical parameters for the 330130-045-02-05 extension cable.
| Parameter | Specification |

Note: This cable is part of a matched system. Using a cable with different specifications or length can alter the system's calibration and output, leading to inaccurate vibration and position measurements. The -02-05 suffix typically specifies connector types and a top-exit orientation.
Application Scenarios
This extension cable is an essential part of installing a proximity transducer system on machinery where the probe and the signal conditioner cannot be mounted close together.
Shaft Vibration and Position Monitoring Systems:
Used to connect 8mm proximity probes measuring radial vibration or axial position on turbines, compressors, and large pumps to their corresponding 3300 NSv Proximitor modules located in a nearby junction box or control panel.
API 670 Compliant Machinery Protection:
An integral component in building a monitoring system that meets the API 670 standard for machinery protection systems, which specifies the use of qualified, matched component systems for critical measurements.
Retrofits and System Repairs:
Commonly used as a direct replacement for a damaged or faulty extension cable in an existing 3300 XL or 3300 NSv transducer system to restore proper system function and calibration.
OEM Machinery Integration:
Supplied by Original Equipment Manufacturers (OEMs) with their machinery to provide a complete, pre-specified proximity transducer system for the end-user, ensuring optimal performance and ease of installation.
Signal Transmission in Standard Installations:
Enables the proximitor to be located in a more accessible or environmentally controlled area while the probe is installed directly on the machine bearing housing. The 4.5-meter length is a standard, versatile size for many industrial applications.
