Bently Nevada 330905-05-08-05-12-05 | 80mm NSv Probe

Product Overview

The Bently Nevada 330905-05-08-05-12-05 is a high-precision 3300 NSv Proximity Probe featuring an M10x1 thread and an 80mm case length. Designed specifically for process compressor applications, the NSv series offers enhanced chemical resistance and superior side-view characteristics compared to legacy RAM and 3000-series probes. This non-armored configuration includes a 0.5-meter FluidLoc cable and a miniature coaxial ClickLoc connector, making it ideal for tight-clearance machinery. The probe assembly is built for durability, with a total weight of approximately 0.32 kg.

Technical Specifications

Core Performance Advantages

Chemical & Process Resilience: Utilizing Polyphenylene Sulfide (PPS) for the tip and AISI 304 Stainless Steel for the case, the NSv series is built to withstand corrosive industrial environments. The integrated Viton O-ring ensures a reliable differential pressure seal between the tip and case.
Interchangeable Integration: This probe is electrically and mechanically compatible with previous 3300 RAM systems, ensuring a seamless transition for facilities upgrading their vibration monitoring equipment.
High-Speed Dynamics: With a frequency response of 0 to 10 kHz, the 3300 NSv accurately tracks rapid rotor transients and vibration profiles even with field wiring lengths up to 305 meters.

Installation & Torque Guide

• Mounting: Maximum thread engagement for the M10x1 case is 15 mm. For the first three threads, the maximum rated torque is 22.6 N•m; a recommended torque of 7.5 N•m ensures a secure fit without overstressing.
• Cable Management: The FluidLoc FEP-insulated cable requires a minimum bend radius of 25.4 mm (1.0 in). Avoid sharp kinks to maintain the 75 Ω coaxial impedance.
• Connector: The ClickLoc connector should be tightened finger-tight. The maximum rated torque for the connector interface is 0.56 N•m.

Technical FAQs

Q1: What is the resistance of the 0.5-meter probe?
A1: The DC resistance from the center conductor to the outer conductor (RPROBE) for this 0.5m module is 4.0 ± 0.5 ohms.

Q2: Is this probe compatible with small shaft axial measurements?
A2: Yes, though targets smaller than 13 mm (0.5 in) may affect the scale factor. Reducing the gap setting below the standard 1.0 mm can help stabilize measurements on smaller shafts.

Q3: How do I request a quote for this Bently Nevada part?
