The 330101-20-45-05-02-05 is an 8mm proximity probe from the 3300 XL series manufactured by Bently Nevada. It is one of the most widely used eddy current sensors in global industry, specifically designed for synchronous, non-contact condition monitoring of rotating machinery.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-metre system also fully complies with the American Petroleum Institute’s (API) 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward-compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components.This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

When using the 330101-20-45-05-02-05 probe, it is essential to ensure that the total system length strictly matches the 3300 XL Proximitor calibration to avoid measurement errors. During installation, use a multimeter to precisely adjust the DC gap voltage (typically to the -10V linear midpoint) and ensure the probe tip is free from metal debris. Additionally, strictly adhere to the minimum bend radius of the cable, use connector protectors to prevent oil contamination, and verify that the 2.0-inch unthreaded length is fully seated within the mounting hole to prevent interference or damage to the probe case.
