Bently Nevada 330101-00-43-15-02-00 3300 XL 8 mm Proximity Probe

Description

Fully threaded 3/8-24 UNF probe body (Option 00) with a 4.3 in case length (Option 43) and a 1.5 m total length (Option 15) specifies this 3300 XL 8 mm probe configuration — 330101-00-43-15-02-00. This unarmored, non-contacting probe pairs with a 3300 XL Proximitor sensor and an extension cable to measure physical displacement. The probe operates using the eddy-current principle to track static and dynamic distance variations between the probe tip and a conductive target material, typically an AISI 4140 steel shaft.

This configuration employs a standard cable with a ClickLoc connector without a connector protector (Option 02) and is supplied without agency approvals (Option 00). The PPS plastic probe tip and the stainless steel case provide durability in environments containing lubricating oil or steam. This variant serves applications where external conduit or cable armor is not required.

Features

• Fully threaded 3/8-24 UNF thread body with 0.0 in unthreaded length (Option 00)
• 4.3 in overall case length (Option 43) for deep-reach machinery mounting
• 1.5 m total cable length (Option 15) with standard unarmored coaxial construction
• Miniature coaxial ClickLoc connector (Option 02) without connector protector
• Standard model without agency approvals (Option 00)
• Viton O-ring pressure seal built into the probe tip and case assembly
• PPS plastic tip material with stainless steel case

Applications

• Steam and gas turbine shaft vibration and axial position measurement
• Compressor and pump rotor displacement monitoring
• Critical rotating machinery protection and machinery diagnostics
• Bearing clearance measurement and oil film thickness analysis

Installation Guidelines

Install the probe by setting the appropriate probe gap according to the system calibration, which is typically set at -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements. Route the coaxial cable with proper shielding and grounding practices standard for vibration monitoring systems to prevent electrical noise interference. Ensure the thread engagement does not exceed 0.563 in (14.3 mm) for the 3/8-24 UNF threads to avoid binding during installation.
