Bently Nevada 330102-00-20-50-02-00 3300 XL 8 mm Proximity Probe

The Bently Nevada 330102-00-20-50-02-00 is a 3300 XL 8 mm proximity probe with a 3/8-24 UNF thread and 5.0m armored cable. It provides non-contacting vibration and position measurements for high-speed compressors and space-restricted machinery.

Comprehensive Vibration and Position Monitoring

The Bently Nevada 330102-00-20-50-02-00 is a high-performance 3300 XL 8 mm proximity probe engineered for precise vibration and position monitoring in industrial machinery. Because it utilizes advanced eddy current technology, the sensor provides non-contacting measurements by generating an electromagnetic field at the probe tip. This specific model excels in monitoring small-diameter shafts or applications where space is extremely restricted, such as in centrifugal compressors and high-speed refrigeration units. Moreover, it delivers a standard sensitivity of 7.87 V/mm (200 mV/mil), which ensures accurate tracking of radial vibration and axial thrust position.

Robust Construction for Demanding Environments

To ensure long-term reliability in harsh industrial zones, this probe features a 5.0-meter integrated cable protected by stainless steel armor. This armored casing provides superior resistance against mechanical abrasion and chemical exposure, while the FEP jacket maintains the cable’s electrical integrity. Furthermore, the 330102-00-20-50-02-00 includes the ClickLoc miniature coaxial connector. This specialized connection mechanism offers a secure, gold-plated interface that resists loosening due to machinery vibration. Consequently, the system maintains a stable signal even when installed in proximity to high-power electrical equipment, thanks to its enhanced RFI/EMI immunity.

Installation and System Compatibility

This probe is designed with a 3/8-24 UNF threaded body, which simplifies the mounting process into machine housings or specialized brackets. While it is a part of the 3300 XL series, it is also highly effective for replacing legacy 3300 RAM or 3000/7000-series transducer systems. Therefore, it serves as a critical upgrade path for aging machinery protection systems. Although it has a slightly more compact linear range of 1.5 mm (60 mils) compared to larger probes, it provides superior performance in restricted counter-bore environments. By integrating this probe into a 3500 series monitoring rack, operators can achieve 100% Brand New reliability for their predictive maintenance programs.

Functional Advantages

The 330102-00-20-50-02-00 provides essential data for Keyphasor signals and tachometer applications on shafts as small as 51 mm (2 inches). Because it follows a standardized calibration for 4140 steel targets, it ensures consistent data across different machine types. Furthermore, the interchangeability of the 3300 XL components allows for the replacement of individual probes or cables without the need for total system recalibration. This flexibility significantly reduces maintenance costs and operational downtime in power generation and oil and gas facilities.
