330101-00-12-10-12 | Bently Nevada 8 mm Probe 1.0m

Why Choose the 330101-00-12-10-12 for Vibration Monitoring?

When machinery vibration threatens uptime, the 330101-00-12-10-12 from Bently Nevada provides the precise measurement you need. This 3300 XL 8 mm probe is engineered for robust performance in demanding industrial environments. With a 1.0 metre total length and a miniature coaxial ClickLoc connector, it integrates seamlessly into your existing monitoring system.

The 8 mm probe design features a thicker encapsulation of the probe coil in molded PPS plastic, making it more rugged against physical abuse. The larger diameter probe body also provides a stronger, more robust case. This durability translates to longer service life and reduced maintenance costs.

Key Features and Technical Specifications

Every specification of the 330101-00-12-10-12 is designed to deliver accurate, reliable data. Here are the critical parameters:

• Product Type: 3300 XL 8 mm Probe with 3/8-24 UNF thread, without armor
• Total Length: 1.0 metre (3.3 feet)
• Connector: Miniature coaxial ClickLoc with FluidLoc cable
• Unthreaded Length: 0.0 inches
• Overall Case Length: 1.2 inches
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Probe Case Material: AISI 303 or 304 stainless steel

The patented TipLoc molding method ensures a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength. The optional FluidLoc cable prevents oil and other liquids from leaking out of the machine through the cable's interior, enhancing reliability in lubricated environments.

Real-World Applications

This probe is ideal for monitoring radial vibration in rotating machinery such as turbines, compressors, and pumps. Its 2 mm linear range (from 0.25 to 2.3 mm) with an incremental scale factor of 7.87 V/mm (200 mV/mil) ensures precise measurements. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils).

In applications where oil mist or liquid ingress is a concern, the FluidLoc cable option provides an extra layer of protection. This makes the 330101-00-12-10-12 a dependable choice for harsh industrial settings.

Installation and Setup

Proper installation is critical for accurate readings. The probe uses a 3/8-24 UNF thread for mounting. Field wiring should be 0.2 to 1.5 mm² (16 to 24 AWG), preferably a 3-conductor shielded triad cable with tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Always follow the frequency response graphs to account for signal rolloff at high frequencies with longer wiring.

Maintenance and Reliability

Routine inspection of the probe and cable is recommended to ensure optimal performance. The probe operates in temperatures from -52°C to +177°C (standard) and can withstand humidity up to 93% with minimal scale factor change. The stainless steel case and PPS tip resist corrosion and wear, reducing the need for frequent replacements.

Compatibility and Integration

The 330101-00-12-10-12 is part of the Bently Nevada 3300 XL family, designed to work with 3300 XL Proximitor Sensors and monitoring systems. The ClickLoc connector ensures a secure, quick connection, while the FluidLoc cable option is compatible with standard extension cables. Verify compatibility with your existing system before ordering.

Troubleshooting Common Issues

If you encounter erratic readings, check the cable connection and ensure the probe tip is clean and properly positioned. The nominal probe DC resistance should be 7.59 ± 0.50 ohms for a 1.0 metre probe. If readings are unstable, verify the gap voltage is within the recommended range. For persistent issues, consult the Bently Nevada manual or contact Petro Auto Tech.
