The Bently Nevada 330904-00-23-05-01-00 is a 3300 XL NSv (Narrow Side View) Proximity Probe, designed for radial vibration and axial position measurements on small-shaft machinery with tight installation constraints. It is specifically used in centrifugal compressors, refrigerators, and process gas machines.

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 where a small shaft or reduced side-view is present:

Radial vibration and radial position measurements

Axial (thrust) position measurements

Tachometer and zero speed measurements

Phase reference (Keyphasor signals)

Product Applications

Electric power industry: Used for bearing vibration monitoring of gas turbines, steam turbines and generators to prevent equipment failures caused by rotor imbalance or improper alignment.

Oil and gas: Applied to large centrifugal compressors and gathering and transportation pumps in offshore drilling platforms or onshore refineries.

Petrochemical industry: State monitoring of key pumps (such as cracking gas compressors, re-cracking units) to ensure the continuous and safe operation of chemical production lines.

Heavy industry and metallurgy: Axial displacement monitoring of key rotating equipment such as large blowers, coal mills and rolling mills to avoid major accidents caused by collision between moving and stationary parts.

Shipbuilding engineering: Axial system monitoring of propulsion systems of large ocean-going vessels.
