The Bently Nevada 330101-00-12-10-12-00 is a precision-engineered 8 mm probe from the trusted 3300 XL series. This model uses a 3/8-24 UNF thread and comes without armor for standard applications. It provides non-contact measurement of shaft vibration and position. This specific configuration includes a 1.0-meter (3.3 feet) total length. It also features the Miniature coaxial ClickLoc connector with FluidLoc cable. Therefore, it ensures stable, accurate data for turbomachinery monitoring. Users benefit from its robust design and advanced manufacturing techniques.
The Bently Nevada 330101-00-12-10-12-00 offers precise electrical characteristics. The nominal DC resistance (RPROBE) measures 7.59 ± 0.50 Ω. This resistance is measured from the center conductor to the outer conductor. The probe cable uses high-quality materials to ensure signal integrity.
Additionally, the 3300 XL design incorporates several patented improvements. The TipLoc molding method creates a robust bond between the probe tip and body. Furthermore, the CableLoc design provides 330 N (75 lbf) pull strength. This securely attaches the probe cable and tip for enhanced durability.
The linear range for this sensor is 2 mm (80 mils). It begins at approximately 0.25 mm (10 mils) from the target. The range extends from 0.25 to 2.3 mm (10 to 90 mils). This corresponds to approximately –1 to –17 Vdc. The recommended gap setting for radial vibration is -9 Vdc. This equals approximately 1.27 mm (50 mils).
The Bently Nevada 330101-00-12-10-12-00 demonstrates excellent accuracy. The Incremental Scale Factor (ISF) is 7.87 V/mm (200 mV/mil) for a 1-meter system. This includes an interchangeability error of ±5%. This measurement occurs over the 80 mil linear range. The temperature range for this rating is 0°C to +45°C (+32°F to +113°F).
Moreover, the Deviation from Best Fit Straight Line (DSL) is minimal. For a standard 1-meter system, it is less than ±0.025 mm (±1 mil). This high linearity ensures reliable and repeatable measurements. The extension cable capacitance is typically 69.9 pF/m (21.3 pF/ft). Field wiring can be 0.2 to 1.5 mm² (16 to 24 AWG). We recommend using 3-conductor shielded triad cable with tinned wiring. The maximum field wiring length is 305 meters (1,000 feet).
Understanding the physical specifications ensures proper installation. The Bently Nevada 330101-00-12-10-12-00 features a 3/8-24 UNF thread. The unthreaded length option is 0.0 inches (Option '00'). The overall case length is 1.2 inches (Option '12'). The probe weighs approximately 323 g/m (11.4 oz).
Furthermore, the operating temperature range is critical. The standard probe operates between -52°C to +177°C (-62°F to +350°F). However, exposing the probe to temperatures below –34˚C (-30˚F) may cause premature seal failure. The pressure seal uses a Viton® O-ring. This seals differential pressure between the tip and case.
Additionally, the probe handles humid conditions well. Testing shows less than a 3% change in Average Scale Factor (ASF). This testing occurs in 93% humidity per IEC standard 68-2-3 for up to 56 days. The probe case is AISI 303 or 304 stainless steel (SST). The probe tip is molded from Polyphenylene sulfide (PPS). This provides thicker encapsulation of the coil for increased ruggedness.
Proper installation maximizes the lifespan and performance of the sensor. First, clean the mounting surface thoroughly before installation. The 3/8-24 UNF threads require careful alignment. Next, thread the probe into the mounting hole by hand to avoid cross-threading. Tighten it to the recommended torque specifications.
Additionally, handle the 1.0-meter cable with care to prevent damage. Avoid sharp bends that could compromise the insulation. The Miniature ClickLoc connector should lock securely. This ensures a reliable electrical connection. Finally, set the initial gap to the recommended -9 Vdc. This provides optimal performance for radial vibration monitoring.

1. What is the primary application for this probe?
The 330101-00-12-10-12-00 is designed for non-contact vibration and position monitoring. It is commonly used in turbines, compressors, and pumps for machinery protection.
2. What is the advantage of the 8 mm probe design?
The 8 mm probe provides a thicker PPS plastic encapsulation around the coil. Therefore, it offers a more rugged probe body. The larger diameter also provides a stronger, more robust case against physical abuse.
3. Does this model come with agency approvals?
No, this specific configuration has the '00' agency approval option. This means it does not carry CSA, ATEX, or IECEx certifications. It is intended for general-purpose monitoring applications.
4. How do I choose between standard and FluidLoc cable?
The '12' connector option includes FluidLoc cable. This prevents oil leakage through the cable interior. However, consider your specific application carefully. The FluidLoc option may not be necessary for all installations.
5. What is the recommended gap setting for this probe?
The recommended gap setting for radial vibration is -9 Vdc. This corresponds to approximately 1.27 mm (50 mils) from the target surface. This setting ensures optimal linearity and performance.
