330101-00-08-20-12-CN | Bently Nevada 8 mm Probe 2.0 m Cable

Introduction to the Bently Nevada 330101-00-08-20-12-CN

When machinery vibration threatens uptime, the 330101-00-08-20-12-CN from Bently Nevada provides accurate, real-time data. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and comes without armor. With a 2.0 meter (6.6 feet) total length and a miniature coaxial ClickLoc connector with FluidLoc cable, it is designed for harsh industrial environments. The probe offers a linear range of 2 mm (80 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil) ±5% over the standard temperature range.

Key Features & Technical Specs

• Probe Type: 3300 XL 8 mm, 3/8-24 UNF thread, without armor.
• Total Length: 2.0 meters (6.6 feet).
• Connector: Miniature coaxial ClickLoc connector with FluidLoc cable.
• Linear Range: 2 mm (80 mils), from 0.25 to 2.3 mm (10 to 90 mils).
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% (standard 5 or 1 meter system at 0°C to +45°C).
• Probe Tip Material: Polyphenylene sulfide (PPS).
• Probe Case Material: AISI 303 or 304 stainless steel.
• Operating Temperature: -52°C to +177°C (standard probe).
• Weight: 323 g/m (11.4 oz).
• Recommended Gap Setting for Radial Vibration: -9 Vdc (approximately 1.27 mm / 50 mils).

One distinctive spec is the patented TipLoc molding method, which provides a robust bond between the probe tip and body. This reduces the risk of failure in high-vibration applications.

Applications & Use Cases

This probe is ideal for rotating machinery such as turbines, compressors, and pumps. In oil and gas facilities, the FluidLoc cable prevents oil leakage through the cable interior, enhancing safety. The 8 mm probe’s thicker encapsulation offers superior ruggedness against physical abuse, making it suitable for heavy industrial environments.

Installation & Setup

Mount the probe using the 3/8-24 UNF thread. Ensure the gap setting is approximately -9 Vdc for radial vibration measurements. Field wiring should 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 monitor. Follow the manufacturer’s manual for precise alignment and torque specifications.

Maintenance & Reliability

Inspect the probe periodically for physical damage, especially the tip and cable. The patented CableLoc design provides 330 N (75 lbf) pull strength, reducing cable breakage. The probe is designed to seal differential pressure with a Viton O-ring; avoid exposing it to temperatures below -34°C (-30°F) to prevent pressure seal failure. Regular verification of the scale factor ensures measurement accuracy.

Compatibility & Integration

The 330101-00-08-20-12-CN is part of the 3300 XL series and works with Bently Nevada Proximitor sensors and monitoring systems. It integrates with standard field wiring up to 305 meters. The miniature coaxial ClickLoc connector ensures a secure connection. For specific system compatibility, consult the official Bently Nevada documentation.
