330910-00-11-10-02-05 Bently Nevada 1.0m NSv Proximity Probe

Product Overview

The Bently Nevada 330910-00-11-10-02-05 is a high-precision 3300 NSv series proximity probe designed for critical vibration monitoring in confined industrial spaces. Featuring a metric M10 x 1 thread and integrated stainless steel armor, this sensor is engineered for small-bore applications where standard probes encounter side-wall interference. The Narrow Side View (NSv) technology provides superior lateral clearance, making it ideal for centrifugal process compressors and small-shaft machinery. This model includes multiple agency approvals for versatile deployment across various global industrial standards.

Technical Specifications

Mechanical Design & Material Advantages

1. Fully Threaded 110mm Housing: This probe is configured with a 110 mm overall case length and no unthreaded portion, allowing for maximum flexibility in mounting depth within M10 x 1 threaded ports. Despite the robust construction, the system maintains a typical weight of approximately 14 to 150 g (0.5 to 5.3 oz) depending on the armor and cable setup.

2. Superior Chemical Resistance: The 3300 NSv series features a probe tip made of PPS (Polyphenylene sulfide), offering significantly higher resistance to aggressive chemicals and process gasses than legacy probes. A Viton® O-ring ensures a reliable pressure seal between the tip and the case, suitable for complex centrifugal compressor environments.

3. Advanced Signal Integrity: Equipped with a ClickLoc miniature coaxial connector, the probe ensures a secure, vibration-resistant electrical path. The integrated stainless steel armor protects the FEP-insulated cable from mechanical damage while maintaining a minimum bend radius of 25.4 mm (1.0 in).

Installation Guidelines

Gap Calibration: The recommended installation gap is 1.0 mm (40 mils). The linear range begins approximately 0.25 mm (10 mils) from the target surface. For optimal performance on small shafts, ensure the target diameter is at least 13 mm (0.5 in).

Torque Specifications: For M10x1 threaded cases, the recommended installation torque is 11.3 N•m (100 in•lb). Do not exceed the maximum rated torque of 33.9 N•m to prevent permanent damage to the sensor housing.

Field Wiring: To maintain frequency response (0 to 10 kHz), ensure the distance between the Proximitor Sensor and the monitor does not exceed 305 meters (1,000 feet) using recommended three-conductor shielded triad cable.

Technical FAQs

Q: Is this probe compatible with older 3300 RAM systems?
A: Yes, the 3300 NSv series is mechanically and electrically interchangeable with Bently Nevada’s previous 3300 RAM proximity probes and extension cables.

Q: What does the -05 Agency Approval option signify?
A: The -05 option indicates "Multiple Approvals," meaning the probe is certified for use in various hazardous area classifications (such as ATEX, IECEx, and CSA) globally.

Q: What target size is required for accurate measurement?
A: While the minimum target size is 8.9 mm, a 13 mm (0.5 in) diameter is recommended. Smaller targets may result in a change in the scale factor, requiring gap adjustments.
