Description

Option 00 (0.0 in unthreaded length) and Option 60 (6.0 in overall case length) specify this 3300 NSv proximity probe configuration with stainless steel armor — 330909-00-60-10-01-CN. This specialized 3300 NSv proximity probe is designed for eddy-current displacement measurements in industrial environments requiring high mechanical durability and localized certifications. The integrated flexible stainless steel armor provides robust defense against mechanical damage and physical wear, while the pre-installed connector protector shields the miniature ClickLoc coaxial connection from oil, moisture, and particulate ingress. The system is certified under the -CN suffix, which delivers comprehensive China hazardous area approvals including NEPSI and CCC compliance.

Part of the 3300 XL NSv Proximity Transducer System, this probe is engineered for tight spaces, small-bore machinery, and constrained target geometries where standard-size proximity probes cannot fit. It pairs seamlessly with the 330930 extension cable and 330980 Proximitor sensor to form a fully calibrated non-contact vibration and axial position measurement system. Its high side-view immunity and compact envelope make it suitable for centrifugal compressors, aeroderivative gas turbines, and other high-speed rotating equipment with tight clearances.

Features

• Option 00 unthreaded design provides a fully threaded 3/8-24 UNF-2A case for maximum mounting adjustability and precise gap calibration.
• Option 60 delivers a 6.0-inch overall case length suitable for deep-reach installation ports and thick-walled machine casings.
• Option 10 specifies a 1.0-meter (39 in) total probe length, simplifying routing to local junction boxes and connection interfaces.
• Option 01 features a miniature coaxial ClickLoc connector pre-fitted with a fluorosilicone connector protector.
• Suffix -CN integrates China-specific hazardous area certifications including NEPSI and CCC compliance.
• Flexible AISI 302 stainless steel armor protects the coaxial lead cable from abrasion, sharp bends, and physical impacts.

Applications

• Vibration and axial position monitoring in small-bore machinery and high-speed rotating shafts.
• Non-contact shaft displacement measurements on aeroderivative gas turbines.
• Thrust and radial displacement sensing in high-speed centrifugal compressors.
• Industrial machinery protection systems operating under NEPSI and CCC hazardous area regulations.

Installation Guidelines

• Ensure a minimum probe tip separation of 25 mm (1.0 in) for axial installations, or 23 mm (0.9 in) for radial configurations, to avoid signal cross-talk.
• Install the probe using the recommended torque of 11.3 N m (100 in lb) and never exceed the maximum rating of 33.9 N m (300 in lb).
• Maintain the minimum coaxial cable bend radius of 25.4 mm (1.0 in) during routing to prevent structural degradation of the conductor shield.
• Verify the pre-installed fluorosilicone connector protector is seated correctly over the ClickLoc junction to prevent exposure to industrial fluids and particulates.

Compliance and Certifications

• NEPSI: Certified for intrinsically safe and explosion-proof environments in mainland China under the -CN package.
• CCC: China Compulsory Certification compliant for hazardous area electrical equipment.
• CE: Meets European Union EMC Directive 2014/30/EU standards.
• RoHS: Complies with European Directive 2011/65/EU and China RoHS regulations.
• Functional Safety: Qualified for use in SIL 2 (HFT = 0) and SIL 3 (HFT = 1) safety-instrumented systems.
