Description

330901-00-12-10-02-05: 3300 NSv proximity probe, featuring a 1/4-28 UNF standard thread without armor, configured with 0.0 inches of unthreaded length (Option 00) and a 1.2-inch case length (Option 12). This non-contact eddy-current sensor is part of the 3300 XL NSv Transducer System, specifically optimized for machinery with tight physical clearance and reduced target geometries. The configuration includes a 1.0-meter overall cable length (Option 10), a miniature coaxial ClickLoc connector with standard cable (Option 02), and multiple international hazardous area approvals (Option 05).

This standard-mount probe provides precise displacement, shaft vibration, and axial position measurements in compact industrial environments. Unlike variants equipped with stainless steel armor or specialized FluidLoc oil-barrier jackets, this configuration is designed for installations where physical protection is provided by standard conduit or machine enclosures, maintaining a low mechanical profile and high chemical resistance via its polyphenylene sulfide tip.

Features

• Option 00 unthreaded case length allows for full-depth thread engagement within mounting ports.
• Option 12 overall case length provides a compact 1.2-inch body suitable for shallow-access bores.
• Option 10 total length specifies a 1.0-meter (39-inch) integrated probe cable for direct routing to local junctions.
• Option 02 ClickLoc miniature coaxial connector provides a secure, vibration-resistant connection to the extension cable without the added bulk of an integrated connector protector.
• Option 05 multiple approval option enables installation in hazardous environments, carrying CSA, ATEX, and IECEx certifications.
• Patented TipLoc molding process creates a high-integrity bond between the polyphenylene sulfide probe tip and the stainless steel case.
• Patented CableLoc design provides up to 220 N (50 lb) of pull strength between the probe lead and the probe case.

Applications

• Centrifugal air compressors, refrigeration compressors, and process gas compressors.
• Radial vibration and radial position measurements on shafts smaller than 51 mm (2.0 in).
• Axial (thrust) position measurements on flat targets smaller than 15 mm (0.6 in).
• High-speed turbomachinery with counterbore, side-view, or rear-view restrictions.
• Tachometer speed sensing and Phase reference (Keyphasor) applications.

Technical Specifications

Installation Guidelines

• Do not exceed a maximum thread engagement length of 0.375 inches for 1/4-28 UNF threaded cases to prevent binding.
• Maintain a minimum bend radius of 25.4 mm (1.0 inch) along the coaxial cable run to prevent signal degradation.
• Clean and align ClickLoc connectors before mating. Hand-tighten and apply a maximum of 0.56 N-m (5 in-lb) connector-to-connector torque.
• Avoid routing probe cables parallel to high-voltage AC lines or near sources of electromagnetic interference.
• Install according to Bently Nevada drawing 141092 for intrinsically safe systems, or drawing 140979 for non-incendive/non-sparking systems.
