Bently Nevada 330910-00-12-10-02-00 3300 NSv Proximity Probe

Description

Fully threaded M10x1 metric steel probe case with 0 mm unthreaded length (Option 00), 120 mm overall case length (Option 12), 1.0 m total cable length (Option 10), and integrated stainless steel armor specifies this configuration — 330910-00-12-10-02-00. This non-contact eddy-current 3300 NSv Proximity Probe is used for shaft vibration and axial position measurement on high-speed rotating machinery with limited target geometry and small clearances. The integrated stainless steel armor protects the coaxial cable from abrasion, physical impacts, and mechanical wear in harsh operational environments.

This configuration features a Miniature ClickLoc coaxial connector (Option 02) without a connector protector. Unlike variants configured with the -05 approval option, this model specifies Option 00, indicating no hazardous area agency approvals are required. The transducer system operates by transmitting radio frequency signals from the 3300 XL NSv Proximitor Sensor to the probe tip, creating an eddy-current field that measures the distance between the probe tip and the observed shaft.

Features

• Metric M10x1 threaded case with integrated AISI 302 stainless steel armor for high mechanical protection.
• Unthreaded length of 0 mm (Option 00) and case length of 120 mm (Option 12) for deep-reach installation requirements.
• Coaxial cable length of 1.0 m (39 in) with a standard 75 ohm fluoroethylene propylene (FEP) insulated jacket.
• Miniature coaxial ClickLoc connector (Option 02) provides a secure, lock-in connection to the extension cable.
• Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case material offer high chemical resistance.
• Rated for operating temperatures between -52 degC and +177 degC.

Applications

• Radial vibration and axial position monitoring on high-speed rotating shafts.
• Small-bore machinery, aeroderivative gas turbines, and centrifugal compressors.
• Applications with limited installation clearances and small target shaft diameters (smaller than 20 mm).
• Industrial machinery protection in power generation, chemical, oil and gas, and wastewater industries.

Installation Guidelines

• Avoid exceeding recommended mounting thread length to prevent binding during installation.
• Ensure minimum counterbore clearance of 13 mm (0.5 in) where applicable to maintain specified scale factor.
• Route the armored cable to avoid sharp bends (minimum bend radius of 25 mm for armored coaxial cables).
• Keep probe-to-cable connections dry and clean. The use of a connector protector is recommended if exposed to fluids.
• Calibrate or verify the gap setting of 1.0 mm (40 mils) using a caliper or thickness gauge prior to system startup.

Compliance and Certifications

• This configuration (Option 00) does not require or carry specific hazardous area approvals.
• General compliance with industrial electrical safety and environmental directives where applicable (such as RoHS).
