330101-00-08-10-02-CN | Bently Nevada 8 mm Probe, 1.0 m Cable

Introduction to the 330101-00-08-10-02-CN

When machine vibration threatens uptime, the 330101-00-08-10-02-CN from Bently Nevada provides precise measurement. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and operates without armor. It is designed for industrial rotating machinery where accurate proximity sensing is critical.

Key Features and Technical Specifications

The 330101-00-08-10-02-CN delivers an incremental scale factor of 7.87 V/mm (200 mV/mil) with ±5% interchangeability error over its 2 mm linear range. Key specs include:

• Linear range: 2 mm (80 mils), starting at 0.25 mm from target.
• Recommended gap setting for radial vibration: -9 Vdc (approximately 1.27 mm).
• Probe tip material: Polyphenylene sulfide (PPS).
• Probe case material: AISI 303 or 304 stainless steel.
• Operating temperature range: -52°C to +177°C (standard probe).
• Cable length: 1.0 metre (3.3 feet) with miniature coaxial ClickLoc connector.
• Probe DC resistance: 7.59 ± 0.50 Ω (for 1.0 m probe).

Compared to similar 5 mm probes, the 8 mm design offers thicker encapsulation and a more rugged case, enhancing durability in harsh environments.

Applications and Use Cases

Industries such as power generation, oil and gas, and manufacturing rely on the 330101-00-08-10-02-CN for shaft vibration and position monitoring. Its robust construction withstands high temperatures and pressure differentials, making it suitable for turbine and compressor applications.

Installation and Setup

Mount the probe using the 3/8-24 UNF thread. Field wiring requires 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. Maximum cable length between the Proximitor sensor and monitor is 305 meters (1,000 feet). Ensure the gap is set to -9 Vdc for radial vibration measurements.

Maintenance and Reliability

Regularly inspect the probe tip and cable for wear. The patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength, reducing the risk of cable detachment. Avoid exposing the probe to temperatures below -34°C to prevent pressure seal failure.

Compatibility and Integration

The 330101-00-08-10-02-CN works with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. It is compatible with standard 5 or 1 meter systems and extended temperature range configurations.
