Bently Nevada 330104-00-08-50-01-05 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-00-08-50-01-05 is an 8 mm proximity probe from the 3300 XL series. It features a permanently attached 5-meter armored cable and is designed for non-contact measurement of vibration, position, or speed in rotating machinery. This probe forms one part of a complete transducer system that includes a compatible Proximitor® sensor.

Despite its compact size, the 8 mm probe delivers high accuracy with a standard sensitivity of 7.87 V/mm (200 mV/mil). Its small diameter allows installation in tight spaces where larger probes cannot fit—such as between bearing housings or on small-diameter shafts. Therefore, it is especially useful in high-speed turbomachinery and space-constrained industrial equipment.

Typical Applications

This probe is widely used in compressors, small steam turbines, gearboxes, and pumps. It supports machinery protection, condition monitoring, and Keyphasor® reference signal generation. Because of its hazardous area certifications, it is also deployed in oil & gas, chemical processing, and power plants where explosion-proof operation is required.
