The 330930-045-04-00 is a dedicated extension cable for the 3300 NSv series proximity transducer system manufactured by Bently Nevada. Unlike the standard 3300 XL series, the 3300 NSv (Narrow Surface version) system is specifically optimized for small shaft diameters, small targets, or confined mounting spaces. This extension cable plays a vital role in providing the physical connection and signal transmission throughout the entire transducer loop.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
The primary uses for the 3300 NSv Transducer System are for areas where counter bore, sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in).
The 3300 NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 NSv system may use the existing probe, extension cable, and monitoring system with 3300 NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components.

High-Speed Pumps
Used at miniature fluid-film bearings of boiler feed pumps to route probe leads and monitor radial vibration of high-speed small shafts.
Micro Turbines
Used for rotor condition monitoring in micro gas turbines, providing reliable signal transmission inside highly confined casings.
Industrial Refrigeration
Used for small-diameter rotors in centrifugal chiller compressors, pairing with NSv probes for axial displacement measurement in tight spaces.
Packaging Machinery
Used in miniature main shaft mechanisms of rotary filling machines, the -04 armor withstands frequent high-pressure washdowns.
Semiconductor
Used for precision relative displacement monitoring of ultra-small servo motors or high-speed air bearing shafts in wafer robot arms.
Pharma-Chemicals
Used for continuous online mechanical condition monitoring inside bearing housings of high-speed miniature agitators or centrifuges.
When utilizing this stainless steel armored extension cable, field technicians must strictly verify the 4.5-meter length specification and ensure it is only mated with an NSv probe that has a 0.5-meter integrated tail cable.
During routing installation within external metal conduits or cable trays, the minimum physical bend radius of the armored body must not be less than 25.4 mm, and applying a static tensile load exceeding 220 Newtons to the cable is strictly prohibited.
Furthermore, once the gold-plated miniature ClickLoc coaxial connectors at both ends are secured by finger-tightening, the integrated anti-contamination connector protectors must be physically tightened to isolate the physical signal path from the wetting and ingress of high-temperature oil contaminants, process fluids, and condensing steam around the bearing housing
In terms of physical specifications, this cable features a total length of 4.5 meters (14.8 feet) and incorporates a high-density coaxial core wire with a nominal impedance of 75 ohms, with both ends equipped with proprietary gold-plated brass miniature ClickLoc locking physical connectors. To withstand variable mechanical and chemical environments on industrial sites, its exterior is clad in a flexible AISI 302/304 stainless steel armored protective layer, which is further wrapped with a fluorinated ethylene propylene (FEP) insulation jacket, while also integrating connector protectors to block the ingress of external process fluids or oil contaminants. Under physical and material configurations, the component accommodates a static tensile load of up to 222 Newtons (50 pounds-force) and supports long-term deployment across a high-and-low temperature range from -35°C to +200°C as well as in 100% condensing humidity environments. During practical wiring installation, this 4.5-meter extension cable serves as the physical signal path, establishing an end-to-end physical mating with an NSv probe that has a 0.5-meter integrated tail cable and the corresponding Proximitor Sensor to form a standard 5.0-meter monitoring loop, enabling completely standardized plug-and-play component replacement in subsequent plant supply chain maintenance.
It is a 3300 NSv series proximity transducer extension cable manufactured by Bently Nevada.
How to correctly use and install the 330930-045-04-00 cable?
Connect one end to the integral cable of a 3300 NSv probe and the other end to a 3300 NSv Proximitor. Lock the connectors via the ClickLoc mechanism, and it is recommended to use heat-shrink tubing externally for waterproofing.
Can 330930-045-04-00 work alone and output vibration signals?
No. It is merely an intermediate physical connection cable and must be paired with a 3300 NSv probe and a 3300 NSv Proximitor Sensor as a 3-piece system to function.
What is the connector type of 330930-045-04-00?
It features Bently Nevada's patented ClickLoc miniature coaxial connectors on both ends (one male, one female) with an anti-loosening design.
Can 330930-045-04-00 be interchanged with 3300 XL 8mm series products?
No. The internal electrical parameters of the 3300 NSv (Narrow Gap version) differ from the standard 3300 XL 8mm. The 330930 cable must never be connected to 3300 XL probes or Proximitors.
