Bently Nevada 330851-06-000-070-50-00-05 3300 XL NSv Proximity Probe
The Bently Nevada 330851-06-000-070-50-00-05 is a 3300 XL NSv Proximity Probe featuring an M10 x 1 metric thread and a 7.0-meter integrated cable. Designed for small shaft vibration and confined spaces, it offers high-precision displacement sensing and robust ClickLoc connectivity for critical machinery protection systems.
Product Description
The Bently Nevada 330851-06-000-070-50-00-05 functions as a specialized displacement sensor within the 3300 XL NSv (Non-Standard vent) Proximity Transducer System. This probe is specifically engineered for applications where standard 8mm probes cannot be used due to tight physical clearances or small target diameters. Because the NSv system utilizes a unique side-view rejection technology, it prevents interference from surrounding metal, ensuring that the signal represents only the actual vibration or position of the target shaft.
Furthermore, this configuration features a metric M10 x 1 thread with a 60mm case length, making it ideal for international machinery designs. The probe is equipped with a 7.0-meter total length, which often eliminates the need for an intermediate extension cable, thereby reducing the number of connection points and potential failure locations in the signal path. Since it is constructed with a high-strength polyphenylene sulfide (PPS) tip and a stainless steel case, it maintains high-precision measurements even in the presence of corrosive lubricants and extreme thermal cycles found in industrial rotating equipment.
