Product Description
The Bently Nevada 330780-50-CN is part of the 3300 XL 11 mm Proximity Transducer System. It is designed to measure vibration and position in demanding industrial environments using non-contact eddy current technology. With a larger 11 mm probe tip, it offers an extended linear range compared to 8 mm systems, making it suitable for applications like axial thrust and rod position monitoring in turbines and compressors.
