The Bently Nevada 330703-050-120-10-02-00 is an 11 mm proximity probe from the 3300 XL series used for non-contact measurement of shaft vibration and displacement in rotating machinery.
It is part of a modular eddy current proximity transducer system widely used in industrial condition monitoring and machinery protection applications. The probe is typically installed with a matching extension cable and Proximitor sensor to form a complete measurement chain for turbines, compressors, pumps, and generators.
This configuration is commonly selected for installations requiring a longer mechanical probe body (120 mm class) and flexible mounting adaptability in deeper or heavy-duty machine housings.
