Product Description:

The Bently Nevada 330909-00-90-10-02-05 is a 3300 NSv (Narrow Side View) Proximity Probe for high-precision, non-contact monitoring of critical rotating machinery. Its narrow field of view, chemical corrosion resistance, and optimized capability for small targets make it the industry standard for centrifugal air compressors, refrigeration compressors, and process gas compressors with extremely tight space constraints.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).The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. 

Frequently Asked Questions (FAQ)

Q:How do you prevent cross-talk during installation?

A:When installing proximity probes on small-diameter shafts, the proximity of their emitted electromagnetic fields can cause interference (cross-talk). To avoid erroneous readings, you must maintain a physical tip-to-tip separation of at least 25 mm (1.0 in) for axial measurements and 23 mm (0.9 in) for radial vibration configurations.
Q:What is the electrical scale factor and range of this sensor?
A:The system features an Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil). It offers a reliable linear measurement range of 1.5 mm (60 mils), which intentionally balances a tight side-view profile with precise distance monitoring.

Q:What are the primary applications for this specific probe?
A:The 3300 XL NSv (No Side-view) system is engineered for confined installation spaces or machinery with small target footprints. It is commonly used in centrifugal air compressors, refrigeration compressors, process gas compressors, and small-shaft rotating machinery where standard 5 mm or 8 mm probes will not fit.
