330910-10-22-10-01-CN Bently Nevada NSv Proximity Probe

Product Overview

The Bently Nevada 330910-10-22-10-01-CN is a high-performance 3300 NSv series proximity probe featuring an M10 x 1 thread and integrated stainless steel armor. The NSv (Narrow Side View) series is specifically engineered for confined installation spaces, small-shaft applications, and centrifugal process compressors. Compared to standard probes, it features a more concentrated magnetic field, effectively reducing side-wall interference. Furthermore, this probe is designed with enhanced chemical resistance, making it an ideal choice for upgrading legacy 3300 RAM systems or performing precision monitoring in harsh industrial environments.

Technical Specifications

Mechanical Design & Application Advantages

1. Deep-Hole Mounting Design: This model features an extended 220 mm overall case with a 100 mm unthreaded section. This structure is ideal for applications requiring passage through thick machine casings or deep mounting pedestals, ensuring that the probe tip can accurately reach internal monitoring points while maintaining a secure M10 x 1 thread engagement.

2. Superior Chemical Resistance & Sealing: The probe tip is constructed from PPS (Polyphenylene sulfide), offering significantly higher resistance to process gases and chemical media compared to traditional probes. An internal Viton O-ring ensures differential pressure seal stability between the tip and the case, providing long-term reliability for complex operating conditions.

3. ClickLoc Secure Connection: Utilizing the ClickLoc miniature coaxial connector with a dedicated connector protector, this configuration effectively prevents signal attenuation caused by oil, moisture, or physical vibration. The stainless steel armor further protects the FEP-insulated cable from mechanical wear.

Installation Guidelines

Gap Setting: The recommended installation gap for the 3300 NSv probe is 1.0 mm (40 mils). The linear range begins at 0.25 mm from the target. For the most accurate measurement results, a minimum target diameter of 13 mm (0.5 in) is recommended.

Torque Limits: For the M10 x 1 threaded case, the recommended installation torque is 11.3 N•m (100 in•lb). Never exceed the maximum rated torque of 33.9 N•m during installation to avoid damaging the precision sensor housing.

Field Wiring: To ensure signal integrity, the maximum length of the three-conductor shielded triad cable between the Proximitor Sensor and the monitor should not exceed 305 meters (1,000 feet) to prevent high-frequency signal roll-off.

Technical FAQs

Q: What is the difference between the NSv probe and the standard 3300 XL 8mm probe?
A: NSv stands for "Narrow Side View." Its magnetic field shape is optimized to concentrate primarily forward. This allows it to be installed in narrow counterbores or to monitor small-diameter shafts with significantly less side-wall interference than standard probes.

Q: What does the -CN option represent?
A: The "-CN" suffix typically indicates that the product complies with specific country regulations (such as China), including localized explosion-proof certifications, labeling standards, or relevant import requirements.

Q: Is the connector protector mandatory?
A: In environments with heavy oil mist, moisture, or dust, the connector protector significantly improves the electrical stability of the coaxial joint, preventing environmental contaminants from causing signal anomalies. It is highly recommended for industrial site installations.
