The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements.The primary uses for the 3300 XL 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). It is primarily used in the following applications on fluid-filmed bearing machines

Petrochemical Industry
Installed on high-speed centrifugal seal gas compressors. Due to the small shaft diameters and extremely tight internal spaces, the 3300 NSv probe is used to monitor radial vibration, preventing damage to seal faces caused by excessive vibration.
Power Generation Industry
Used in micro-turbines or emergency diesel generator sets to monitor axial displacement.This prevents axial movement caused by sudden load changes from damaging internal blades.
Air Separation Industry
Applied in ultra-high-speed turboexpanders. These machines rotate at tens of thousands of RPM; the probe provides the Keyphasor signal for precise speed measurement and phase analysis.
Food & Beverage Industry
Installed on high-speed centrifugal separators. It monitors the dynamic balance of the main shaft through non-contact measurement, preventing structural fatigue caused by imbalance during production.
Rail Transit Industry
Used in centrifugal compressors for train air conditioning systems. The compact size of the 3300 NSv fits perfectly into the small internal spaces of these units, ensuring long-term reliability for passenger comfort.
When using the 330904-00-12-05-02-05 probe, it is essential to ensure strict compatibility with the 3300 NSv dedicated preamplifier and cable. Incompatibility with the standard XL series probes is strictly prohibited. Due to its narrow linear range, the output voltage must be monitored during installation to precisely lock it at the linear midpoint of approximately -10V. Furthermore, its explosion-proof certification should be utilized in conjunction with a safety barrier, and unauthorized cutting of the cable to maintain system impedance is strictly prohibited. Finally, the M8 miniature probe requires robust impact protection, and the coaxial connector must be tightly insulated and moisture-proofed to ensure signal stability in oily or confined spaces.
The 330904-00-12-05-02-05 is a 3300 XL NSv (Narrow Side View) series Eddy Current Proximity Probe manufactured by Bently Nevada.
How to use products like the 330904-00-12-05-02-05?
To use it, thread its metric M8 case into the machine's mounting hole, adjust the gap between the probe tip and the shaft surface to the linear region (typically corresponding to a gap voltage of around -10V), and then connect its 0.5-metre cable to a 3300 XL NSv Proximitor via an extension cable.
What is the biggest advantage of the 330904-00-12-05-02-05 compared to standard 8 mm probes?
Its biggest advantage is that its side magnetic field is very narrow. When the probe must be installed in deep holes (counterbores) or environments with metal walls on the sides, it will not generate false measurement readings due to side-metal interference.
What is the primary function of the 330904-00-12-05-02-05 in the system?
Its primary function is to continuously and accurately sense minute displacements using the eddy current principle without contacting the shaft surface. It is often used in equipment like small centrifugal compressors to provide real-time monitoring of radial vibration and axial displacement.
What should be paid attention to in the daily maintenance of the 330904-00-12-05-02-05?
The maintenance focus is on keeping the ClickLoc connector clean to avoid contamination of the interior by oil or moisture; although the cable is armored, sharp bends smaller than 25.4 mm at the connector base must still be avoided.
