Bently Nevada 330901-05-65-05-11-05 3300 NSv proximity probe

Frequently asked questions
Q:Is the 330901-05-65-05-11-05 approved for hazardous locations?
A:Yes. The 05 approval option provides Multiple Approvals. When installed as part of a certified 3300 XL NSv transducer system and in accordance with the applicable installation requirements, it is suitable for approved hazardous-area applications.

Q:Why is the 3300 XL NSv probe used instead of a standard 5 mm or 8 mm probe?
A:The NSv probe is specifically designed for installations where counterbore, side-view, or rear-view clearance limits prevent the use of standard proximity transducer systems. Its compact sensing tip allows reliable measurements in confined spaces.

Q:Is this model supplied as a complete transducer system?
A:No. The 330901-05-65-05-11-05 is the proximity probe only. It must be used with a compatible 3300 NSv extension cable and 3300 XL NSv Proximitor® Sensor to form a complete transducer system.

Description

The Bently Nevada 330901-05-65-05-11-05 is a 3300 XL NSv proximity probe designed for use with the 3300 XL NSv Proximity Transducer System. The complete transducer system consists of a 3300 NSv proximity probe, a 3300 NSv extension cable, and a 3300 XL NSv Proximitor® Sensor. It is specifically developed for rotating machinery where installation space is restricted, making it suitable for applications with limited counterbore diameter, side-view clearance, or rear-view access. The system complies with the performance requirements of API Standard 670 for proximity transducer systems. This configuration includes a 1/4-28 UNF threaded probe without stainless-steel armor, a 0.5-inch unthreaded length, a 6.5-inch case length, a Miniature ClickLoc™ coaxial connector with connector protector and standard cable, and Multiple Approvals for hazardous-area installations. The probe incorporates TipLoc™ molding, which securely bonds the probe tip to the probe body, and CableLoc™ technology, which improves cable retention and pull strength. Gold-plated ClickLoc connectors provide a reliable electrical connection and help prevent connector loosening caused by machine vibration. When used with the matching 3300 NSv extension cable and 3300 XL NSv Proximitor Sensor, the 330901-05-65-05-11-05 provides accurate non-contact measurement of shaft vibration, radial shaft position, axial position, Keyphasor® reference, and rotational speed.

Application areas

• Compact Machinery Protection Systems – Used in industrial rotating equipment where installation restrictions prevent the use of standard Bently Nevada 3300 and 3300 XL 5 mm or 8 mm transducer systems. Typical applications include compact compressors, auxiliary turbomachinery, and fluid-film bearing machines requiring continuous vibration and position monitoring.
• Oil & Gas and Petrochemical Equipment – Installed on critical rotating assets such as compressor trains and process machinery where reliable condition monitoring is required. The 3300 XL NSv system helps maintenance teams identify changes in shaft behavior early and supports predictive maintenance strategies for continuous production equipment.
• Industrial Machinery Retrofit Projects – Used when upgrading older monitoring installations or replacing legacy systems in applications with limited installation space. The 3300 XL NSv design provides a practical solution for improving shaft vibration and position monitoring without major mechanical modifications.
