330101-00-13-15-02-CN | Bently Nevada 8 mm Probe 1.5m

Introduction to the 330101-00-13-15-02-CN

When machinery vibration threatens uptime, the 330101-00-13-15-02-CN from Bently Nevada provides precise measurement. This 3300 XL 8 mm probe uses a 3/8-24 UNF thread and comes without armor. It is designed for eddy-current vibration monitoring in rotating equipment.

This probe is part of the trusted 3300 XL series, known for rugged construction and reliable performance. The 330101-00-13-15-02-CN includes a miniature coaxial ClickLoc connector and a standard cable. Its total length is 1.5 meters (4.9 feet), making it suitable for many mounting configurations.

Key Features and Technical Specifications

• Manufacturer: Bently Nevada
• Product Type: 3300 XL 8 mm probe with 3/8-24 UNF thread
• Unthreaded length: 0.0 inches
• Overall case length: 1.3 inches
• Total length: 1.5 meters (4.9 feet)
• Connector: Miniature coaxial ClickLoc
• Probe tip material: Polyphenylene sulfide (PPS)
• Probe case material: AISI 303 or 304 stainless steel

The probe's patented TipLoc molding method creates a robust bond between tip and body. The CableLoc design provides 330 N (75 lbf) pull strength, securing the cable and tip. These features reduce the risk of mechanical failure in demanding environments.

Real-World Applications

In petrochemical plants, the 330101-00-13-15-02-CN monitors shaft vibration on pumps and compressors. Its 2 mm linear range (80 mils) captures critical vibration data. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils).

For turbines and generators, this probe helps detect early signs of imbalance or misalignment. The 7.87 V/mm (200 mV/mil) incremental scale factor ensures accurate readings. With a temperature range of -52°C to +177°C, it operates reliably in harsh conditions.

Installation and Setup

Proper installation is key to accurate measurements. The probe case thread is 3/8-24 UNF, with a maximum thread engagement of 0.563 inches. For standard forward-mounted probes, the recommended torque is 11.2 N•m (100 in•lbf).

For the first three threads, use a maximum torque of 22.6 N•m (200 in•lbf) and a recommended 7.5 N•m (66 in•lbf). Always follow the manufacturer's guidelines to avoid damage. Field wiring should use 3-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) to the monitor.

Maintenance and Reliability

Regular inspection of the probe and cable is essential. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring. Although not pressure-tested before shipment, you can contact the custom design department if testing is needed.

The probe's relative humidity performance shows less than a 3% change in Average Scale Factor when tested in 93% humidity per IEC standard 68-2-3 for up to 56 days. This ensures stable operation in humid environments.

Compatibility and Integration

The 330101-00-13-15-02-CN works with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector provides a secure, quick connection. Use the specified field wiring to maintain signal integrity over long distances.
