Bently Nevada 330103-15-23-05-02-CN 3300 XL 8 mm Proximity Probe

Description

Option 15 (150 mm unthreaded length) and Option 02 (ClickLoc connector, standard cable) specify this metric 3300 XL 8 mm probe configuration — 330103-15-23-05-02-CN proximity probe. This eddy-current transducer system component operates on a non-contact basis to monitor shaft vibration, position, and speed on rotating machinery. Featuring an unarmored cable design with an M10 x 1 thread, this specific configuration complies with national safety standards for explosive environments in industrial processing plants.

The probe utilizes a polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case to withstand high pressures and chemical exposure in industrial environments. Suffix -CN indicates compliance with Chinese hazardous area approvals (NEPSI and CCC), verifying that the electrical barrier and explosion-proof parameters are fully certified for safety-critical plant monitoring installations.

Features

• M10 x 1 metric thread structure without protective armor (base configuration)
• 150 mm unthreaded length (Option 15) for deep casing penetration
• 230 mm overall case length (Option 23) providing physical reach
• 0.5 meter (1.6 feet) total probe cable length (Option 05)
• Miniature coaxial ClickLoc connector (Option 02) with standard triaxial FEP-insulated cabling
• Integrated -CN suffix certification delivering compliance with NEPSI and CCC safety frameworks
• Full backward compatibility and physical interchangeability with non-XL 3300 series 5 mm and 8 mm components

Applications

• Radial vibration and axial thrust position monitoring on fluid-film bearing machines
• High-speed industrial steam turbine and gas turbine machinery protection
• Keyphasor reference and rotating shaft speed measurements
• Centrifugal compressor and multi-stage pump vibration diagnostics in chemical processing plants

Installation Guidelines

• Observe a maximum thread engagement length of 15 mm for the metric M10 x 1 casing thread.
• Tighten the standard forward-mount probe case to 7.5 N-m (66 in-lbf) recommended torque, with an absolute maximum rating of 22.6 N-m (200 in-lbf).
• Verify that the gold-plated male ClickLoc connector is joined only finger-tight with its mating extension cable connector.
• Maintain a cable routing path with a bend radius no smaller than 25.4 mm (1.0 inch) to prevent mechanical attenuation of the signal.

Compliance and Certifications

• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation)
• CCC (China Compulsory Certification) for hazardous environments
• CE Compliant
