Bently Nevada 330103-00-14-10-01-00 3300 XL 8 mm Proximity Probe

Description

330103-00-14-10-01-00: 3300 XL 8 mm metric proximity probe, M10 x 1 thread, featuring a 0 mm unthreaded length (Option 00), 140 mm overall case length (Option 14), 1.0 meter total length (Option 10), and a ClickLoc connector with a connector protector (Option 01) without agency approvals (Option 00). This unarmored metric proximity probe is a key sensor option within the 3300 XL 8 mm transducer family, engineered for direct mechanical installation in machinery casings. The integrated connector protector provides robust physical shielding at the coaxial connection point to safeguard signals against moisture, oil, and dust ingress.

Unlike armored configurations (such as the 330104 series) or configurations lacking a connector protector (Option 02), this assembly utilizes a standard unarmored coaxial cable terminated with a miniature coaxial ClickLoc male connector. The probe connects directly to a 3300 XL extension cable to form a complete 5-meter or 9-meter transducer system. This system utilizes eddy-current technology to measure the gap change between the probe tip and the observed shaft, delivering precise voltage outputs proportional to dynamic vibration and static position on fluid-film bearing machinery.

Features

• M10 x 1 Metric Thread: Direct non-armored body design (Option 330103) for standard metric mechanical installations.
• 0 mm Unthreaded Length: Fully threaded casing (Option 00) allows maximum adjustment during installation and gapping.
• 140 mm Overall Case Length: Extended case length (Option 14) facilitates mounting in deep-well or thick-wall machinery housings.
• 1.0 Meter Total Length: Standard short lead (Option 10) intended to match 3300 XL extension cables in standard system configurations.
• Connector Protector (Option 01): Standard unarmored coaxial cable featuring a miniature ClickLoc male connector with a pre-installed environmental protector.
• No Agency Approvals (Option 00): Suitable for non-hazardous locations and general industrial monitoring applications.
• Thick PPS Encapsulation: Molded polyphenylene sulfide (PPS) tip protects the inner probe coil against fluid erosion and abuse.

Applications

• Shaft radial vibration monitoring in high-speed industrial rotating machinery.
• Axial position and thrust displacement measurements on steam turbines, gas turbines, and compressors.
• Keyphasor reference speed measurements and phase reference sensing.
• Condition monitoring of fluid-film bearings in harsh power generation and oil and gas processing environments.

Installation Guidelines

• Mounting Hole Preparation: Ensure the mounting hole is tapped cleanly for M10 x 1 metric threads. Thread depth must match casing and must not exceed 15 mm of thread engagement to prevent probe binding.
• Mechanical Torque: Tighten the probe body to the recommended standard torque for M10 threads; do not exceed structural limits as casing damage may occur.
• Probe Gapping: Set probe distance from the target using a feeler gauge or by monitoring the Proximitor sensor output voltage (typically -10 Vdc for a standard mid-range gap of 1.27 mm).
• Connector Protection: Slide the pre-installed connector protector firmly over the ClickLoc coupling once connected to prevent chemical or moisture contamination at the signal junction.
• Cable Routing: Observe a minimum cable bend radius of 25.4 mm (1.0 in) along the installation path to avoid damage to the coaxial core conductor.
