The Bently Nevada 330191-00-33-90-05 is a 3300 XL 8 mm Extended Temperature Range (ETR) proximity probe designed for precision measurement of shaft vibration and position in rotating machinery. It is part of the Bently Nevada 3300 XL transducer system and is engineered to deliver stable, non-contact measurement performance in harsh industrial environments.

This model is configured with a 9.0-meter integral cable (90 option) and multiple agency approvals (05 option), making it suitable for installations requiring extended reach and certified compliance. It is widely used in turbines, compressors, pumps, and generators where continuous condition monitoring is critical for equipment protection and predictive maintenance.

The probe uses eddy-current sensing technology to measure the distance between the probe tip and a conductive target surface, enabling both static (position) and dynamic (vibration) measurements with high accuracy.
