330101-00-12-10-12-00 | Bently Nevada 8 mm Probe 3/8-24 UNF

Solving the Challenge of Reliable Vibration Measurement

When machinery vibration threatens uptime, the 330101-00-12-10-12-00 from Bently Nevada provides the precise measurement you need. This 3300 XL 8 mm probe is engineered for robustness and accuracy, helping you detect issues before they escalate into costly failures.

With a linear range of 2 mm (80 mils), this probe delivers dependable data for radial vibration monitoring. The recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) ensures optimal performance in most applications.

Key Features and Technical Specifications

• Probe type: 3300 XL 8 mm, 3/8-24 UNF thread, without armor.
• Total length: 1.0 metre (3.3 feet), with unthreaded length of 0.0 inches and overall case length of 1.2 inches.
• Connector: Miniature coaxial ClickLoc with FluidLoc cable option.
• 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 1-meter systems.
• Deviation from best fit straight line: less than ±0.025 mm (±1 mil) for standard systems.
• Probe tip material: Polyphenylene sulfide (PPS); case material: AISI 303 or 304 stainless steel.
• Operating temperature range: -52°C to +177°C for standard probe.

One standout feature is the patented TipLoc molding method, which creates a stronger bond between the probe tip and body. This design reduces the risk of tip detachment, enhancing long-term reliability in demanding environments.

Real-World Applications

In industries like power generation, oil and gas, and manufacturing, the 330101-00-12-10-12-00 is used to monitor rotating equipment such as turbines, compressors, and pumps. Its robust construction and precise measurement capabilities make it suitable for continuous vibration monitoring in harsh conditions.

For example, a plant engineer might install this probe on a critical pump to track shaft vibration. By catching abnormal vibration early, they can schedule maintenance proactively, avoiding unplanned downtime.

Installation and Setup

Proper installation is key to accurate readings. The probe uses a 3/8-24 UNF thread for mounting. Ensure the mounting surface is clean and the probe is tightened to the recommended torque (refer to the manual). The ClickLoc connector simplifies cable attachment, and the FluidLoc cable option helps prevent oil leakage through the cable interior.

Field wiring should use 3-conductor shielded triad cable with tinned wiring, sized 0.2 to 1.5 mm² (16 to 24 AWG). Maximum cable length between the proximitor and monitor is 305 meters (1,000 feet). Always follow the manufacturer's installation guide for best results.

Maintenance and Reliability

Regular inspection of the probe and cable is recommended to ensure reliable operation. Check for physical damage, loose connections, or signs of wear. The probe is designed to withstand harsh environments, but periodic verification of the gap voltage and scale factor helps maintain accuracy.

By following a routine maintenance schedule, you can extend the service life of the probe and avoid unexpected failures. This proactive approach reduces overall maintenance costs and improves equipment availability.

Compatibility and Integration

The 330101-00-12-10-12-00 is part of the Bently Nevada 3300 XL family, designed to work with 3300 XL extension cables and proximitor sensors. It is compatible with standard Bently Nevada monitoring systems that accept 8 mm probes.
