Bently Nevada 330910-00-05-02-00 3300 NSv Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 05 (50 mm overall case length) specify this 3300 NSv armored metric probe configuration — 330910-00-05-02-00, a rugged 3300 NSv proximity probe designed with integrated stainless steel armor. It is used in tight installations and reduced target area scenarios where conventional 5 mm or 8 mm proximity systems cannot be deployed due to sideview or counterbore limitations. The probe features integrated M10x1 metric threads and robust stainless steel armor to protect the coaxial cable from physical abrasion, crushing, and harsh mechanical environments.

This variant is specifically configured for applications requiring a fully threaded casing of 50 mm without any unthreaded portion at the tip. It utilizes standard coaxial cable terminated with a miniature coaxial ClickLoc connector and is intended for non-hazardous locations where agency approvals are not required. It pairs with the 3300 XL NSv Proximitor Sensor (330980) and 3300 NSv Extension Cable (330930) to form a complete non-contact eddy-current measurement system.

Features

• M10x1 metric threaded probe body with integrated stainless steel armor for high mechanical protection.
• Option 00 unthreaded length specifies a fully threaded 0 mm profile.
• Option 05 overall case length provides a compact 50 mm threaded housing.
• Miniature coaxial ClickLoc connector secures connection and resists loosening under vibration.
• Standard coaxial cable construction with gold-plated brass connector contacts.
• Patented TipLoc molding delivers a secure bond between the polyphenylene sulfide (PPS) probe tip and the steel body.
• Patented CableLoc design provides up to 220 N pull strength at the cable-to-probe junction.

Applications

• Centrifugal air compressors and industrial refrigeration compressors.
• Process gas compressors and high-speed turbomachinery with limited installation clearances.
• Small-bore machines with shaft diameters smaller than 51 mm.
• Axial thrust and radial vibration monitoring on flat targets smaller than 15 mm.
• Tachometer, zero speed, and Keyphasor phase reference measurements.

Installation Guidelines

To avoid potential damage during installation, do not exceed the recommended installation torque of 11.3 N m (100 in lb) for this metric M10x1 threaded probe body. The minimum bend radius of 25.4 mm (1.0 in) must be observed for both armored and unarmored cable runs. Connectors must remain dry and free of contaminants; it is recommended to apply silicone self-fusing tape or a connector protector kit to the probe-to-extension cable junction to block moisture and process fluids. The field wiring should use a three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitoring system.
