Description
Designed for high-reliability machinery condition monitoring, the 330101-01-39-10-01-CN is an unarmored proximity probe belonging to the Bently Nevada 3300 XL 8 mm series. This sensor plays a critical role in measuring shaft vibration, position, and speed in critical rotating machinery. By using eddy current technology, it delivers precise dynamic and static distance measurements between the probe tip and the observed conductive target.
This specific configuration features a 3/8-24 UNF thread, a 0.1-inch unthreaded length, and a 3.9-inch overall case length. Equipped with a 1.0-meter (3.3 feet) coaxial cable, it terminates in a miniature coaxial ClickLoc connector with an integrated connector protector. The "CN" designation guarantees compliance with ATEX, IECEx, and Chinese NEPSI hazardous area safety requirements, making it suitable for volatile industrial zones.
Features
- Compatible with the standard Bently Nevada 3300 XL 8 mm Proximity Transducer System.

- Equipped with a connector protector to prevent ingress of oil, moisture, and debris at the connection point.
- Hazardous area certifications tailored for global and Chinese regional compliance.
Applications
- Steam turbines and gas turbines
- Centrifugal, axial, and reciprocating compressors
- High-pressure industrial pumps
- Electric generators and large motors
- Hydrocarbon processing facilities and refineries

Installation Guidelines
To ensure optimal sensor performance and prevent mechanical damage during operation, observe the following guidelines:
- Maintain appropriate clearance around the probe tip to prevent side-loading interference from adjacent metal components.
- Do not exceed the recommended installation torque for the 3/8-24 UNF threads to prevent casing distortion.
- Ensure the ClickLoc connector is properly mated and the connector protector is fully secured to prevent contamination from oil or moisture.
- Adhere to the minimum bend radius requirements for the coaxial cable to avoid internal copper fatigue and signal degradation.
