Product Description
The 330103-17-22-10-12-05 is an 8 mm Eddy Current Proximity Transducer System component from the Bently Nevada 3300 series. This part number represents a complete transducer assembly, integrating an 8 mm proximity probe with a permanently attached 22-foot cable and terminated with a -05 "California Style" connector. This integrated "Tip-to-Card" design ensures optimal signal integrity by eliminating intermediate connection points, allowing direct connection to compatible monitoring system racks. The assembly is engineered for precise measurement of shaft vibration, position (gap), and rotational speed (Keyphasor®) in critical machinery protection applications.
