Bently Nevada 330103-00-04-50-02-00 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 04 (40 mm overall case length) specify this M10 x 1 metric threaded 3300 XL 8 mm proximity probe configuration — 330103-00-04-50-02-00. This configuration incorporates a 5.0-meter standard coaxial cable (Option 50) and a miniature ClickLoc coaxial connector (Option 02) without a connector protector or mechanical armor. The probe has no hazardous area approvals (Option 00), making it suitable for standard industrial environments. This unarmored metric-thread probe connects to a 3300 XL Proximitor sensor for machinery vibration and axial position measurement on rotating shafts.

The sensor operates using eddy-current principles to measure the static and dynamic distance between the probe tip and a conductive target, typically the steel shaft of a turbine, compressor, or pump. The M10 x 1 metric threaded body allows direct installation into tapped machine housings. The 5.0-meter total length is standard for installations where the Proximitor sensor is mounted in a local junction box.

Features

• Option 00 specifies 0 mm unthreaded length on a fully threaded probe case.
• Option 04 specifies a 40 mm overall case length with M10 x 1 metric threads.
• Option 50 provides a 5.0-meter (16.4 feet) total system length with standard coaxial cable.
• Option 02 includes a miniature ClickLoc coaxial connector without a connector protector.
• Option 00 represents a standard non-hazardous area configuration with no agency approvals.
• Molded polyphenylene sulfide (PPS) tip material protects the internal probe coil from chemical and mechanical ingress.
• Wrench flat size of 8 mm on the metric case allows for straightforward torque application during gapping.

Applications

• Shaft vibration and axial position measurements on steam and gas turbines.
• Condition monitoring of centrifugal compressors, pumps, and industrial fans.
• Thrust position and radial vibration monitoring in fluid-film bearing housings.
• Thermal expansion and casing expansion measurements on heavy rotating machinery.

Installation Guidelines

• Standard metric probe thread engagement must not exceed 15 mm.
• Recommended wrench tightening torque is 5.6 N-m (50 in-lb) maximum for M10 threads.
• Maintain a minimum clearance of 8.0 mm from the probe tip to any surrounding metal to avoid side-view interference.
• Set the probe gap to approximately 1.27 mm (50 mils) to establish the -9 Vdc offset calibration center.
• Ensure the coaxial connection is hand-tightened (finger-tight only) for ClickLoc gold-plated connectors.

Compliance and Certifications

The 330103-00-04-50-02-00 proximity probe is a standard non-hazardous area configuration. It is manufactured under ISO 9001 quality management standards and complies with European CE directives for electromagnetic compatibility (EMC) when installed within a shielded enclosure and paired with appropriate 3300 XL instrumentation.
