330910-10-22-10-01-CN 1.0m Cable Bently Nevada Proximity Probe

Introduction to the 330910-10-22-10-01-CN

When machine vibration threatens uptime, the 330910-10-22-10-01-CN provides reliable shaft displacement measurement. This Bently Nevada 3300 NSv proximity probe is designed for permanent installation in rotating machinery. It delivers accurate, repeatable data for protection and condition monitoring.

The probe uses eddy-current technology to sense shaft position relative to the probe tip. This non-contact method eliminates mechanical wear and offers high-frequency response. As a result, it suits critical applications like compressors, turbines, and pumps.

This model includes a 1.0-meter total length and a miniature coaxial ClickLoc connector. The connector protector adds durability in harsh industrial environments. The M10X1 thread with armor provides robust mounting and cable protection.

Key Features and Technical Specifications

The 330910-10-22-10-01-CN is engineered for precise, stable measurements. Its linear range spans 1.5 mm (60 mils), starting at 0.25 mm from the target. The recommended gap setting is 1.0 mm (40 mils), ensuring optimal operating point.

• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±12.5%/-20%
• Deviation from best fit straight line (DSL): less than ±0.06 mm (±2.3 mils)
• Frequency response: 0 to 10 kHz, +0/-3 dB typical
• Probe dc resistance: 4.2 ± 0.5 ohms (for 1.0 m length)
• Operating temperature: -52°C to +177°C
• Probe case material: AISI 304 stainless steel
• Probe tip material: Polyphenylene sulfide (PPS)
• Minimum target size: 8.9 mm diameter (flat target)

The probe's side-view characteristics are superior to the 3000-series 190 probe, making gap setting easier. Additionally, the NSv design offers increased chemical resistance compared to the 3300 RAM probe, expanding its use in process compressors.

Applications and Use Cases

The 330910-10-22-10-01-CN excels in turbomachinery monitoring. It is commonly used on centrifugal compressors, steam turbines, and gearboxes. Its chemical resistance makes it suitable for sour gas and other aggressive media.

Furthermore, the probe is ideal for axial position measurements on shafts. However, for shaft diameters smaller than 13 mm (0.5 in), scale factor changes may occur. Reducing the gap helps limit this effect, as shown in the reference figures.

Because the probe is mechanically and electrically interchangeable with previous 3300 RAM probes, it serves as a drop-in upgrade for existing installations. This compatibility simplifies retrofits and reduces downtime.

Installation and Setup Guide

Proper installation is critical for accurate readings. First, mount the probe using the M10X1 thread. Apply finger tight torque initially; the maximum recommended torque is 0.56 N•m (5 in•lb). Avoid over-tightening to prevent damage.

For the probe case, the recommended torque is 11.3 N•m (100 in•lb), with a maximum of 33.9 N•m (300 in•lb). For the first three threads, use 7.5 N•m (66 in•lb) recommended and 22.6 N•m (200 in•lb) maximum. Always follow the manufacturer's torque specifications.

When routing the cable, maintain a minimum bend radius of 25.4 mm (1.0 in). This prevents damage to the coaxial cable. The probe is designed to seal differential pressure between tip and case, using a Viton O-ring. Note that probes are not pressure tested before shipment; contact the custom design department if pressure testing is required.

Field wiring between the Proximitor Sensor and monitor can be up to 305 meters (1,000 feet). Use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors. For longer runs, refer to the frequency response graphs to account for signal rolloff.

Maintenance and Reliability

The 330910-10-22-10-01-CN requires minimal maintenance due to its non-contact design. However, periodic inspection is recommended to ensure the probe tip is clean and the cable is secure. Verify the gap setting remains within the recommended range.

Because the probe operates in harsh environments, check the armor and connector for wear. The PPS tip resists many chemicals, but avoid physical damage. If the probe is exposed to extreme temperatures, confirm it stays within the -52°C to +177°C range.

Regularly verify the system's frequency response, especially if field wiring length changes. The probe's performance is stable over time, but routine checks help maintain accuracy. Always follow the manufacturer's maintenance manual for detailed procedures.

Compatibility and Integration

The 330910-10-22-10-01-CN is compatible with Bently Nevada 3300 XL NSv Proximitor Sensors. It is also interchangeable with previous 3300 RAM probes and extension cables. This ensures seamless integration into existing monitoring systems.

The miniature coaxial ClickLoc connector simplifies installation and provides a secure connection. The standard cable length of 1.0 meter matches many installation requirements. For longer distances, extension cables are available (0.5, 1, 5, or 7 meters total probe lengths).

Field wiring can extend up to 305 meters, allowing flexible placement of the monitor. The probe's frequency response remains flat up to 10 kHz, making it suitable for high-speed machinery.

Buyer's Guide: Evaluating the 330910-10-22-10-01-CN

When selecting a proximity probe, consider the linear range, scale factor, and environmental ratings. The 330910-10-22-10-01-CN offers a 1.5 mm linear range and a scale factor of 7.87 V/mm, which is ideal for most rotating machinery.

Check the target size: the minimum flat target is 8.9 mm diameter, but 13 mm is recommended for consistent scale factor. For axial measurements on smaller shafts, be prepared to adjust the gap.

Evaluate the chemical resistance: the NSv probe's PPS tip and stainless steel case withstand many process media. If your application involves corrosive gases, this probe is a strong candidate.

Finally, confirm the total length and connector type match your installation. This model includes a 1.0-meter cable with ClickLoc connector, which is standard for many retrofit projects.
