Probe Proksimit Bently Nevada 330910-05-10-02-00 3300 NSv

Description

330910-05-10-02-00: 3300 NSv proximity probe, M10x1 thread, with stainless steel armor, Option 05 unthreaded length, Option 10 overall case length, Option 02 miniature ClickLoc coaxial connector with standard cable, and Option 00 indicating no agency approvals required. This specific metric-threaded configuration is used in tight-clearance industrial applications where mechanical protection is required for the probe cable but external agency approvals are not specified.

Unlike unarmored versions (such as the 330905 probe) or configurations requiring specific connector protectors (Option 01), this armored probe utilizes a flexible AISI 302 stainless steel armor over its FEP-insulated coaxial cable to resist mechanical wear and physical abrasion. The M10x1 metric thread design establishes direct compatibility with metric-tapped machine housings, providing a 1.5 mm (60 mils) linear range for high-accuracy shaft vibration and axial position measurements on high-speed rotating machinery with constrained target areas.

Features

• Stainless steel armor provides physical cable protection from abrasion, pinching, and debris in harsh operating environments.
• M10x1 metric thread allows direct integration into standard metric-tapped machinery cases.
• 50 mm unthreaded case length (Option 05) ensures precise physical clearance adjustment inside the installation port.
• 100 mm overall case length (Option 10) provides the necessary reach for deep-set mounting configurations.
• Miniature coaxial ClickLoc connector (Option 02) features a secure locking mechanism with standard 75 ohm FEP-insulated cable.
• Polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case material offer high chemical resistance and thermal stability.
• Viton O-ring pressure seal prevents process media from leaking through the probe body under differential pressure.

Applications

• Shaft vibration and axial position measurement on high-speed, tight-clearance rotating machinery.
• Small-bore industrial pumps, compressors, and electric motors with limited probe target geometry.
• Aeroderivative gas turbines and auxiliary machinery with metric installation ports.
• Internal monitoring locations prone to mechanical abrasion and fluid exposure.

Technical Specifications

Connections and Interfaces

The 3300 NSv proximity probe terminates in a miniature male coaxial ClickLoc connector designed to pair directly with the 3300 NSv extension cable. This terminal link forms a low-loss, 75 ohm matched impedance connection that channels the RF eddy-current signals back to the Proximitor sensor.

Installation Guidelines

Proper mechanical and electrical installation is critical for ensuring measurement accuracy:

• Thread Engagement: Maintain standard thread engagement limits for the M10x1 thread (maximum 15 mm length of thread engagement to prevent binding).
• Torque Limits: Tighten the M10x1 probe case to the recommended torque of 11.3 N m (100 in-lb). Do not exceed the maximum rated limit of 33.9 N m (300 in-lb).
• Minimum Bend Radius: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) for the armored coaxial cable to avoid structural damage.
• Connector Handling: ClickLoc coaxial connectors must be kept dry and free of contaminants. Finger-tighten the connection, then apply silicone self-fusing tape if exposed to industrial fluids (note: silicone tape is not recommended inside machine casings or if exposed to turbine oil).
• Target Clearance: Verify that the probe tip is positioned at the recommended gap setting of 1.0 mm (40 mils) relative to the target shaft for optimal linear range performance.

Compliance and Certifications

The 330910-05-10-02-00 variant is supplied under Option 00, indicating that hazardous area agency approvals are not required for the intended installation environment. For applications requiring hazardous area certifications (such as ATEX, IECEx, or CSA), please specify the Option 05 variant.
