Description

330102-00-25-10-02-CN is an armored proximity probe featuring a 3/8-24 UNF threaded body with a 0.0-inch unthreaded length (Option 00), a 2.5-inch overall case length (Option 25), a 1.0-meter total system length (Option 10), a miniature coaxial ClickLoc connector on a standard cable (Option 02), and China hazardous area approval (-CN).

This configuration incorporates integral metal armor to protect the coaxial cable from physical abrasion, mechanical impact, and harsh industrial environments. Unlike standard unarmored configurations, this probe provides robust physical guarding along the entire length of its standard cable. The probe operates as part of the 3300 XL 8 mm proximity transducer system, interacting with a 3300 XL extension cable and a 3300 XL Proximitor sensor via eddy-current measurement principles.

Features

• Option 00 specifies a 0.0-inch (0.0 mm) unthreaded length, allowing full case thread engagement during mounting.
• Option 25 designates a 2.5-inch (63.5 mm) overall case length with 3/8-24 UNF threads.
• Option 10 supplies a 1.0-meter (3.3 feet) total cable length for close-coupled installations.
• Option 02 provides a miniature coaxial ClickLoc connector on standard cable without an additional connector protector.
• Suffix -CN integrates China hazardous area approval certified by NEPSI and CCC for intrinsically safe and non-sparking environments.
• Stainless steel armor cladding wraps the standard probe cable to resist cutting, crushing, and routing-related damage.
• Integral Viton O-ring provides a differential pressure seal between the probe tip and case.

Applications

• Machinery vibration and axial position measurement on gas turbines, steam turbines, pumps, compressors, and electric motors.
• Physical protective monitoring in tight or abrasive routings where standard cables risk damage.
• Hazardous area deployments in industrial facilities requiring Chinese NEPSI or CCC conformity.

Installation Guidelines

To establish safe and proper performance, observe the following engineering guidelines when installing this probe:

• Maintain a minimum spacing of 3/8-24 threads during installation, and verify thread engagement limits to prevent binding.
• Ensure the probe tip is spaced away from adjacent metallic components to avoid side-viewing interference.
• Tighten the probe case to standard mounting torque configurations, using a 7/16-inch or M10 hexagonal wrench on wrench flats.
• Secure ClickLoc connectors with finger-tight pressure; do not use excessive torque or metal tools which may damage the gold-plated contacts.
• Route the flexible armored casing to avoid sharp bends, keeping bend radii within standard recommended mechanical limits to prevent crimping the internal coaxial lead.
• Ensure proper grounding of the outer shield through the monitoring rack or enclosure to maintain electrical isolation.
