Bently Nevada 330703-010-040-10-02-CN 3300 XL 11 mm Proximity Probe
The Bently Nevada 330703-010-040-10-02-CN is an 11 mm proximity probe designed for the 3300 XL system. Featuring a 40 mm case length, 1.0 m cable, and M14 x 1.5 metric threads, this sensor provides an extended 4.0 mm linear range for critical axial position and vibration monitoring in large rotating equipment.
Technical Overview
The Bently Nevada 330703-010-040-10-02-CN is a high-performance eddy-current sensor within the 3300 XL 11 mm Proximity Transducer System. This system excels in applications requiring a wider linear range than standard 8 mm probes, providing accurate non-contacting vibration and position measurements. Because it features a larger 11 mm tip, the transducer delivers an extended measurement window, which is essential for monitoring axial (thrust) position and differential expansion in large rotating machinery.
Configuration and Performance Specifications
This specific probe is defined by its detailed part number, which dictates its mechanical and electrical characteristics for industrial integration. The 330703 series utilizes M14 x 1.5 threads for robust mounting. With a “010” unthreaded length and a “040” overall case length, the module offers 10 mm of unthreaded clearance and a total length of 40 mm, making it suitable for standard bearing housing depths. Furthermore, the “10” option indicates a 1.0-meter total lead length, while the “02” connector ensures a secure ClickLocâ„¢ miniature coaxial interface.
The “CN” suffix designates that this module carries country-specific hazardous area approvals for China (NEPSI/CCC), ensuring compliance with local safety regulations. Since the probe tip is constructed from durable polyphenylene sulfide (PPS) and the cable utilizes a high-strength CableLocâ„¢ design, the unit resists 330 N (75 lb) of pull strength. Moreover, the 3300 XL 11 mm system provides a linear range of 4.0 mm (160 mils) and a nominal scale factor of 3.94 V/mm (100 mV/mil), offering superior sensitivity for large-scale displacement tracking.
