What Is the 330101-00-08-05-02-05?

When machinery vibration threatens uptime, the 330101-00-08-05-02-05 from Bently Nevada provides a reliable solution. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and comes without armor. It is designed for accurate displacement measurement in rotating equipment.

With a 0.5 meter (1.6 feet) total length and a miniature coaxial ClickLoc connector, this probe integrates easily into monitoring systems. The unthreaded length is 0.0 inches, and the overall case length is 0.8 inches. Made in the U.S.A., it carries CSA, ATEX, and IECEx approvals.

Key Features and Technical Specs of the 330101-00-08-05-02-05

• Linear Range: 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from target.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems.
• Probe Tip Material: Polyphenylene sulfide (PPS) for durability.
• Probe Case Material: AISI 303 or 304 stainless steel (SST).
• Operating Temperature Range: Standard probe from -52°C to +177°C (-62°F to +350°F).
• Probe DC Resistance: 7.45 ± 0.50 Ω for 0.5 meter length.
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Weight: 323 g/m (11.4 oz).

A distinctive feature is the patented TipLoc molding method, which creates a robust bond between the probe tip and body. This reduces the risk of tip separation in harsh environments, enhancing measurement reliability.

Real-World Applications for the 330101-00-08-05-02-05

In industries like power generation, oil and gas, and manufacturing, the 330101-00-08-05-02-05 monitors shaft vibration and position. It is ideal for turbines, compressors, and pumps where early fault detection prevents costly downtime. The probe's 2 mm linear range accommodates typical vibration amplitudes in rotating machinery. Additionally, its CSA, ATEX, and IECEx approvals make it suitable for hazardous area installations.

Installation Guide for the 330101-00-08-05-02-05

Mount the probe using the 3/8-24 UNF thread into a compatible mounting block. Ensure the target surface is clean and within the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. The maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For best results, follow the manufacturer's installation manual.

Maintenance and Reliability of the 330101-00-08-05-02-05

Regular inspection of the probe tip and cable for physical damage is recommended. The probe's CableLoc design provides 330 N (75 lbf) pull strength, reducing cable pull-out risk. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe sealing material uses a Viton O-ring to maintain differential pressure integrity. Periodic verification of the incremental scale factor ensures measurement accuracy over time.

Compatibility and Integration

The 330101-00-08-05-02-05 works with Bently Nevada 3300 XL extension cables and Proximitor sensors. It is compatible with standard 5 or 1 meter system configurations. The miniature coaxial ClickLoc connector simplifies cable attachment. For extended temperature range applications, use the appropriate probe variant. Always verify system compatibility with your existing monitoring equipment.
