Bently Nevada 330910-00-10-50-02-00 3300 NSv Proximity Probe

Description

The 330910-00-10-50-02-00 3300 NSv proximity probe is a metric threaded sensor configuration featuring an M10x1 thread, integrated stainless steel flexible armor, 0 mm of unthreaded length (Option 00), and a 100 mm overall case length (Option 10). This specific assembly is built with a 5.0 meter total cable length (Option 50), terminated with a miniature coaxial ClickLoc connector (Option 02), and is configured for general-purpose applications where hazardous area agency approvals are not required (Option 00).

Unlike unarmored metric variants in the same series, this configuration provides a flexible stainless steel armor sleeve that guards the transducer cable against physical damage, mechanical wear, and sharp edges inside the machinery enclosure. The 3300 NSv system is applied where target geometry is limited or shaft diameters are small, requiring a specialized eddy-current footprint that differs from standard 8 mm sensor lines. This probe operates within a complete transducer circuit alongside a 3300 NSv extension cable and a 3300 XL NSv Proximitor sensor to track high-speed shaft vibration and axial position.

Features

• M10x1 metric thread body with integrated flexible stainless steel armor for high mechanical protection
• 0 mm unthreaded length (Option 00) paired with a 100 mm overall case length (Option 10)
• 5.0 meter total cable length (Option 50) of standard 75 ohm coaxial cabling
• Miniature coaxial ClickLoc connector (Option 02) for consistent electrical connection to the extension cable
• Option 00 configuration for applications that do not require specialized hazardous area certificates
• Eddy-current system design optimized for small target areas and tight-clearance rotating machinery

Applications

This proximity probe is used on high-speed rotating machinery with narrow target pathways, such as small-bore pumps, centrifugal compressors, aeroderivative gas turbines, and auxiliary machinery. The armored casing makes this variant suited for oil-mist environments, internal machine housings, and areas where physical debris or maintenance activities risk damaging standard coaxial lines.

Installation Guidelines

Thread engagement must not exceed a maximum length of 15 mm for M10x1 metric threaded probe cases to prevent thread binding. Mount the probe case into the bracketry using the recommended mounting torque of 11.3 N m (100 in-lb) to prevent case distortion. Maintain a minimum physical bend radius of 25.4 mm (1.0 in) along the armored cable routing. Protect the coaxial connector connection using self-fusing silicone tape or an approved connector protector kit to block fluid penetration.
