330101-00-13-10-12-CN | Bently Nevada 8 mm Probe 1.0 m

Overview of the 330101-00-13-10-12-CN

When machine vibration threatens uptime, the 330101-00-13-10-12-CN from Bently Nevada provides the precise measurement you need. This 3300 XL 8 mm probe is built with a 3/8-24 UNF thread and a 1.0 meter (3.3 feet) total length, making it a versatile choice for rotating machinery monitoring.

Engineered with patented TipLoc molding, the probe tip bonds securely to the body, reducing the risk of damage during installation and operation. The cable features a patented CableLoc design that delivers 330 N (75 lbf) pull strength, ensuring a reliable connection even in demanding environments.

Key Features & Technical Specifications

• Probe Type: 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor.
• Total Length: 1.0 meter (3.3 feet) with unthreaded length of 0.0 inches and overall case length of 1.3 inches.
• Connector: Miniature coaxial ClickLoc connector with FluidLoc cable (country-specific option CN).
• Nominal Probe DC Resistance: 7.59 ± 0.50 ohms for a 1.0 meter probe.
• Linear Range: 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems.
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) for standard 5 or 1 meter systems.
• Probe Tip Material: Polyphenylene sulfide (PPS) for ruggedness.
• Probe Case Material: AISI 303 or 304 stainless steel (SST).
• Temperature Range: -52°C to +177°C (-62°F to +350°F) for standard probe.

One distinctive spec is the 7.87 V/mm (200 mV/mil) scale factor, which ensures consistent output across the linear range. This high sensitivity allows for accurate vibration detection, helping you catch issues before they escalate.

Applications & Use Cases

This probe is ideal for measuring radial vibration and axial position in turbines, compressors, pumps, and other rotating equipment. Its robust design makes it suitable for harsh industrial environments where physical abuse is a concern. For example, in a petrochemical plant, the 330101-00-13-10-12-CN can reliably monitor shaft vibration, enabling predictive maintenance that reduces unplanned downtime.

Installation & Setup

Installation is straightforward with the 3/8-24 UNF thread, which allows secure mounting into standard probe holders. The ClickLoc connector simplifies cable attachment, and the FluidLoc cable option prevents oil or liquid leakage through the cable interior. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. Always follow the manufacturer’s manual for proper gap setting—typically -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended to ensure reliable operation. Check for physical damage, especially to the tip and cable, and verify that the connector remains secure. The probe is designed to withstand temperatures down to -52°C, but exposing it below -34°C may cause premature failure of the pressure seal, so avoid such conditions. The PPS tip and stainless steel case provide excellent resistance to wear and corrosion, extending service life and reducing replacement costs.

Compatibility & Integration

The 330101-00-13-10-12-CN is part of the 3300 XL family and is compatible with Bently Nevada Proximitor Sensors and monitoring systems. It uses a miniature coaxial ClickLoc connector, which is standard for 3300 XL probes. For integration, ensure the extension cable and Proximitor match the system’s specifications. Refer to the official datasheet for detailed frequency response graphs when using longer field wiring lengths.

Comparison with Similar Probes

• 330101-00-13-10-12-CN – 8 mm probe, 1.0 m cable, standard temperature range, 7.87 V/mm scale factor.
• 330101-00-13-10-12-CN (ETR) – Extended temperature range probe, capable of -52°C to +218°C for the tip, with a slightly different scale factor tolerance.
• 3300 XL 5 mm probes – Smaller diameter, lower robustness, and different linear range (typically 2 mm as well, but with different physical dimensions).

Choosing the 8 mm probe provides a thicker encapsulation of the probe coil in PPS plastic, resulting in a more rugged probe that withstands physical abuse better than smaller alternatives.
