Bently Nevada 3300 NSv Proximity Probe 330910-14-19-10-02-00

Product Overview

The Bently Nevada 330910-14-19-10-02-00 is an extended-reach 3300 NSv series proximity probe designed for complex machinery monitoring. Featuring a metric M10 x 1 thread and rugged stainless steel armor, this probe is engineered for small-bore applications where standard sensors encounter side-wall interference. The Narrow Side View (NSv) technology ensures precision vibration and position data in tight spaces, such as those found in centrifugal process compressors. It remains fully interchangeable with legacy 3300 RAM proximity systems.

Technical Specifications

Mechanical Design & Application Advantages

1. Extended Reach Geometry: This probe is configured with a 190 mm total case length including a 140 mm unthreaded portion. This design is specifically intended for deep-access machine ports where the sensor must pass through thick insulation before the threads engage. Despite its length, the probe remains lightweight, with a typical system weight of approximately 14 to 150 g (0.5 to 5.3 oz) depending on the armor configuration.

2. Enhanced Chemical Resistance: Utilizing high-grade PPS (Polyphenylene sulfide) for the probe tip, the 3300 NSv offers superior protection against aggressive process gases compared to the older 3300 RAM series. A Viton® O-ring ensures a robust pressure seal between the tip and the case, rated for the standard operating temperature range.

3. Narrow Side View Performance: The NSv design focuses the magnetic field primarily forward, minimizing the effects of "side-view" interference. This allows for accurate gapping and vibration measurement on small-diameter shafts or within narrow counterbores that would otherwise cause signal errors in standard 8mm probes.

Installation Guidelines

Gap Calibration: The recommended installation gap for the 3300 NSv is 1.0 mm (40 mils). This centers the probe within its 1.5 mm linear range (-1 to -13 Vdc). For radial vibration monitoring, always ensure the target surface meets the recommended minimum diameter of 13 mm (0.5 in) for optimal scale factor stability.

Torque Specifications: For M10x1 threaded cases, Bently Nevada recommends an installation torque of 11.3 N•m (100 in•lb). Do not exceed the maximum rated torque of 33.9 N•m to ensure the integrity of the precision sensor housing.

Cable Management: The probe cable features a minimum bend radius of 25.4 mm (1.0 in). The miniature coaxial ClickLoc connector is designed for a secure, vibration-resistant fit. When routing field wiring, ensure the total distance to the monitor does not exceed 305 meters (1,000 feet).

Technical FAQs

Q: Is the 3300 NSv probe compatible with my existing 3300 RAM extension cables?
A: Yes, the 3300 NSv series is mechanically and electrically compatible, allowing you to upgrade your sensors without replacing the entire extension cable infrastructure.

Q: What is the benefit of the 140 mm unthreaded length?
A: It allows the probe to be inserted deeply into machine housings where the threaded engagement point is set back from the outer surface, providing stability and reach in complex mechanical assemblies.

Q: Does the -00 Agency Approval option mean the probe is unsafe?
A: No, the -00 option simply means the product has not been specifically certified to hazardous area standards like ATEX or IECEx. It is intended for use in safe area (General Purpose) applications.
