Bently Nevada 330103-00-08-05-02-05 3300 XL 8 mm Proximity Probe

Description

330103-00-08-05-02-05: 3300 XL 8 mm metric proximity probe configured with M10 x 1 threads, 0 mm unthreaded length, 80 mm overall case length, and 0.5 meter total cable length. This specific non-armored configuration features a standard triaxial coaxial cable without a connector protector (Option 02) and holds CSA, ATEX, and IECEx approvals (Option 05) for hazardous industrial locations. It utilizes non-contacting eddy-current technology to measure the physical vibration and axial position of rotating machine shafts.

This variant is distinguished from standard fractional-inch probes (such as the 330101 series) by using metric M10 x 1 thread sizing. Compared to armored variations, the 330103 configuration features a bare triaxial FEP-insulated cable with a 25.4 mm (1.0 in) minimum bend radius. The 0.5 meter cable length is suited for installation inside bearing housings or junction boxes requiring connection to a matching 3300 XL extension cable and Proximitor sensor.

Features

• Option 00 specifies a fully threaded body with 0 mm unthreaded length.
• Option 08 provides an 80 mm overall metric case length.
• Option 05 provides a 0.5 meter (1.6 feet) total probe cable length.
• Option 02 provides a miniature coaxial ClickLoc connector with standard triaxial FEP-insulated cable (no connector protector).
• Option 05 complies with CSA, ATEX, and IECEx agency approvals for hazardous locations.
• M10 x 1 metric thread configuration without protective armor.
• Polyphenylene sulfide (PPS) probe tip material with AISI 303 or 304 stainless steel case body.
• 8.0 mm probe tip diameter.

Applications

• Shaft vibration and axial position measurements in rotating machinery.
• Hydroelectric generators, steam turbines, gas turbines, and compressors.
• Fluid-film bearing monitoring in heavy-industrial machinery.
• Balance-of-plant machinery protection systems matching API 670 requirements.

Installation Guidelines

• Observe the minimum bend radius of 25.4 mm (1.0 in) for the standard FEP-insulated coaxial cable.
• Use a class-matching thread configuration and avoid exceeding the recommended probe case torque of 11.2 N-m (100 in-lbf) during installation.
• Verify thread engagement does not exceed 15 mm for M10 x 1 threads to prevent binding.
• Finger-tighten the ClickLoc connectors. If mating with non-XL stainless steel connectors, finger-tighten plus 1/8 turn using pliers.
• Ensure the probe tip remains clear of adjacent metal structures to avoid target-sensing distortion (maintain a minimum side clearance of 15 mm from bore walls).
