Introduction to the 330101-00-09-10-02-05

When machinery vibration threatens uptime, the 330101-00-09-10-02-05 from Bently Nevada provides the reliable measurement you need. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and a 1.0 meter cable, making it ideal for close-coupled installations in rotating equipment. With its patented TipLoc and CableLoc designs, this probe withstands physical abuse while delivering consistent performance.

Key Features and Technical Specs of the 330101-00-09-10-02-05

• Probe Type: 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor.
• Cable Length: 1.0 meter (3.3 feet) with miniature coaxial ClickLoc connector.
• Linear Range: 2 mm (80 mils) from 0.25 to 2.3 mm (10 to 90 mils) from target.
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems.
• Probe Tip Material: Polyphenylene sulfide (PPS) for robust encapsulation.
• Probe Case Material: AISI 303 or 304 stainless steel.
• Temperature Range: Standard probe operates from -52°C to +177°C (-62°F to +350°F).
• Agency Approvals: CSA, ATEX, IECEx approved.

One distinctive spec is the patented TipLoc molding method, which creates a stronger bond between the probe tip and body, reducing failure risk in high-vibration environments.

Real-World Applications for the 330101-00-09-10-02-05

In turbomachinery and compressor monitoring, the 330101-00-09-10-02-05 excels at measuring shaft vibration and position. Its 8 mm diameter provides thicker encapsulation than smaller probes, offering greater resistance to physical damage. For example, in a steam turbine train, this probe reliably tracks radial vibration, helping prevent unplanned outages. The FluidLoc cable option (available separately) further prevents oil leaks through the cable interior, making it suitable for lubricated environments.

Installation Guide for the 330101-00-09-10-02-05

Mount the probe using the 3/8-24 UNF thread with a recommended torque of 11.2 N•m (100 in•lbf) for standard forward mounting. For the first three threads, use 7.5 N•m (66 in•lbf). The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable, keeping the total length between the Proximitor Sensor and monitor under 305 meters (1,000 feet) to avoid signal rolloff.

Maintenance and Reliability Tips

To maintain accuracy, inspect the probe tip and cable for physical damage during routine shutdowns. The probe’s PPS tip resists chemicals and abrasion, but avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature pressure seal failure. For EPL applications, follow the temperature classification schedule: for T1, ambient range is -55°C to +232°C; for T5, it is -55°C to +40°C. Regular verification of the Incremental Scale Factor ensures measurement integrity over time.
