330901-00-16-05-02-CN Bently Nevada NSv Probe

Product Overview

The 330901-00-16-05-02-CN is a high-performance 3300 NSv (Narrow Side View) proximity probe manufactured by Bently Nevada. Specifically engineered for applications with limited side clearance or small target surfaces, this probe utilizes a 1/4-28 UNF threaded housing for precise mounting. With a compact 1.6-inch case length and an unarmored 0.5-meter cable, it is an essential component for monitoring vibration and radial position in centrifugal compressors, pumps, and other high-speed rotating machinery.

Technical Configuration

Robust Design and Connectivity

Constructed with a premium stainless steel housing, the 330901-00-16-05-02-CN is built to withstand rigorous industrial conditions, including shocks up to 30 g. The unit features a miniature coaxial ClickLoc connector, ensuring a secure, moisture-resistant link to extension cables. Its IP67 ingress protection rating makes it suitable for environments with high humidity (up to 95% non-condensing) and potential exposure to dust or water splashes, while the factory-calibrated electronics ensure immediate "out-of-the-box" accuracy.

Technical Specifications

Installation & Maintenance Guide

During installation, ensure the 1.6-inch case is mounted using the recommended flanged mount to maintain stability against industrial vibration. The 330901-00-16-05-02-CN requires a steady 50 mA power supply and should be connected via its ClickLoc miniature coaxial interface. Maintenance involves periodic inspection of the stainless steel housing for physical damage and verifying that the cable remains within the non-condensing humidity range of 0% to 95%. Due to its ±0.1% annual long-term stability, recalibration intervals are typically extended compared to standard sensors.

Engineering Advantages

• Rapid Response: A response time of under 10ms allows for real-time protection and emergency shutdown capability in critical machinery.
• Thermal Versatility: Designed to operate in a broad temperature spectrum from -40°C up to 125°C without signal degradation.
• Environmental Resilience: The IP67 rating and 30 g shock rating ensure the probe survives the harshest factory floor conditions.
• Narrow Clearance Optimization: The NSv design is specifically calibrated for targets as small as 0.25 inches in diameter, where standard probes would suffer from side-view interference.

Technical FAQs

Q1: What is the benefit of the ClickLoc connector?
A1: The ClickLoc connector provides a tactile "click" to confirm a secure connection, preventing signal loss due to vibration-induced loosening common in standard threaded connectors.

Q2: Does this probe require a separate Proximitor sensor?
A2: Yes, the 330901-00-16-05-02-CN must be used with a compatible Bently Nevada 3300 NSv Proximitor to convert the displacement signal into a usable voltage output.

Q3: Is the 0.5-meter length the total system length?
A3: No, the 0.5-meter (20-inch) specification refers to the probe's lead cable length. The total system length must be matched (typically 5m or 7m) using a corresponding extension cable.
