Bently Nevada 330101-00-09-15-12-CN 3300 XL 8 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 12 (ClickLoc connector, FluidLoc cable) specify this 3300 XL 8 mm probe configuration — 330101-00-09-15-12-CN. This unarmored, threaded 8 mm proximity probe features a 3/8-24 UNF thread profile with a 0.9 in overall case length, a 1.5 m (4.9 ft) total cable length, and the -CN China hazardous area approval package. It operates on the eddy-current principle to measure static (axial position) and dynamic (vibration) shaft displacement against a target, pairing with a 3300 XL Proximitor sensor and extension cable in machinery protection systems.

Unlike standard coaxial cables, the FluidLoc cable option (Option 12) prevents oil, moisture, or gas from migrating through the internal structure of the cable jacket into the terminal housing or conduit. The -CN suffix indicates compliance with NEPSI and CCC certifications, making this specific assembly suitable for hazardous industrial installations in China where explosion protection is strictly regulated.

Features

• Option 00 unthreaded length (0.0 in) for flush or fully threaded installation profiles.
• Option 09 overall case length (0.9 in) with standard 3/8-24 UNF threads.
• Option 12 FluidLoc cable construction prevents fluid migration through the cable jacket.
• Option 15 total length provides 1.5 meters (4.9 feet) of triaxial cable.
• Miniature coaxial ClickLoc connector offers secure connection without a connector protector.
• China hazardous area approval package (-CN) including NEPSI and CCC certifications.
• Polyphenylene sulfide (PPS) tip material provides physical protection for the embedded probe coil.
• AISI 303 stainless steel thread construction resists mechanical wear.

Applications

Typical application scenarios for this configuration include:

• Steam and gas turbine shaft vibration monitoring in environments prone to oil migration.
• Compressor and high-pressure pump rotor displacement measurement.
• Permanent installations in machine casings or bearing housings requiring NEPSI/CCC certifications.
• Industrial rotating machinery protection systems in hazardous locations.

Installation Guidelines

Standard installation practices for this proximity probe configuration include:

• Mount the probe through bearing housings or brackets ensuring correct probe gap per system calibration requirements.
• Observe a minimum cable bend radius of 25.4 mm (1.0 in) to prevent coaxial signal attenuation or physical damage.
• Ensure the FluidLoc cable seal is intact to block moisture or machine fluid migration along the conduit path.
• Implement correct shielding and grounding practices for vibration monitoring installations, ensuring the cable outer conductor is isolated from the machine ground except at the Proximitor sensor.

Compliance and Certifications

• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation) hazardous area approval.
• CCC (China Compulsory Certification) for safety and electromagnetic compliance.
• ATEX / IECEx / CSA (Standard options baseline where applicable; CN-suffix guarantees regional China compliance).
