Bently Nevada 330104-08-16-10-02-00 3300 XL 8 mm Proximity Probe

Description

330104-08-16-10-02-00 is a 3300 XL 8 mm proximity probe configured with an M10 x 1 metric thread and integral stainless steel flexible conduit armor. This specific configuration features an 80 mm unthreaded length (Option 08) combined with a 160 mm overall case length (Option 16), making it suited for deep-well probe sleeve installations or heavy machinery casings requiring extended reach. The probe has a 1.0 meter total length (Option 10) and is terminated with a miniature coaxial ClickLoc connector (Option 02) without an additional connector protector. No hazardous area approvals are required (Option 00) for this configuration.

As an armored variant, this probe features a flexible stainless steel conduit that protects the coaxial cable from physical abrasion, impact, and sharp bends in demanding industrial environments. This armored construction distinguishes it from non-armored siblings like the 330103 series. The M10 x 1 metric thread fits standard metric mountings, and the probe operates as part of a complete 3300 XL transducer system when combined with a matching 3300 XL Proximitor sensor and extension cable. The system measures dynamic shaft vibration, axial position, or speed on rotating machines such as steam turbines, gas turbines, compressors, and gearboxes.

Features

• M10 x 1 metric threaded steel case with a 160 mm overall case length (Option 16).
• 80 mm unthreaded length (Option 08) for specialized deep-reach installations.
• Stainless steel flexible armor over the 1.0 meter standard coaxial cable (Option 10) for robust physical protection.
• Miniature coaxial ClickLoc connector (Option 02) for secure, tool-free connection to extension cables.
• 8.0 mm tip diameter with polyphenylene sulfide (PPS) encapsulation for mechanical strength.
• Operating temperature range of -52 degC to +177 degC (-62 degF to +350 degF) for standard probe environments.
• Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil) when paired with 3300 XL Proximitor sensor.

Applications

• Shaft vibration and axial position monitoring on large rotating machinery.
• Deep-well mounting applications in steam and gas turbine bearings.
• Industrial environments requiring high mechanical protection against cable abrasion and cuts.
• Speed and phase reference (Keyphasor) measurements on industrial shafts.

Installation Guidelines

• Maintain a minimum of 15 mm thread engagement during installation to prevent thread damage or binding.
• Ensure the probe-to-extension cable ClickLoc connector is securely joined; hand-tighten only to prevent damage to gold plating.
• Ensure the flexible conduit armor is routed away from sharp edges or moving parts that could pinch the stainless steel sheath.
• Maintain appropriate clearance around the probe tip (typically a minimum of 40 mm diameter of clear area around the tip) to avoid side-view crosstalk or interference from adjacent metal surfaces.
• Always gap the probe to the midpoint of its linear range (approximately -10 Vdc or 1.27 mm / 50 mils gap) using a voltmeter and Proximitor output prior to final tightening of locking nuts.

Compliance and Certifications

This specific SKU (Option 00) does not require hazardous area approvals. For hazardous area installations (ATEX, IECEx, CSA), select the Option 05 variant of this probe series.
