330101-00-13-05-02-00 | Bently Nevada 3300 XL 8 mm Probe

Introduction to the Bently Nevada 330101-00-13-05-02-00

When machine vibration threatens uptime, the 330101-00-13-05-02-00 from Bently Nevada delivers precise measurement. This 3300 XL 8 mm probe is engineered for eddy-current vibration monitoring in rotating equipment. It features a 3/8-24 UNF thread and a 0.5 meter (1.6 feet) total length, making it a compact yet robust solution for tight installations.

Part of the trusted 3300 XL series, this probe is built to withstand harsh industrial environments. Its rugged design helps reduce false readings and maintenance costs. For engineers seeking dependable vibration data, this probe offers a solid foundation.

Key Features & Technical Specifications

The 330101-00-13-05-02-00 includes several design improvements that enhance reliability:

• Patented TipLoc molding provides a robust bond between probe tip and body.
• Patented CableLoc design offers 330 N (75 lbf) pull strength for secure cable attachment.
• Optional FluidLoc cable prevents oil leakage through the cable interior.
• Thicker PPS encapsulation in the probe tip increases ruggedness.
• Larger probe body diameter strengthens the case against physical abuse.

Key technical parameters include:

• Nominal probe DC resistance: 7.45 ± 0.50 Ω (for 0.5 m probe length).
• Extension cable capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Linear range: 2 mm (80 mils), from approximately 0.25 to 2.3 mm (10 to 90 mils).
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5% (for 5 or 1 meter systems).
• Deviation from best fit straight line: less than ±0.025 mm (±1 mil) for 5 or 1 meter systems.
• Probe tip material: Polyphenylene sulfide (PPS).
• Probe case material: AISI 303 or 304 stainless steel.
• Operating temperature range (standard probe): -52°C to +177°C (-62°F to +350°F).

These specs ensure accurate, repeatable measurements across a wide range of conditions.

Applications & Use Cases

The 330101-00-13-05-02-00 is ideal for radial vibration monitoring on pumps, motors, fans, and turbines. Its 8 mm size fits many standard mounting configurations. The 0.5 meter cable length suits installations where the sensor is close to the monitor. For example, in a motor bearing housing, this probe can detect early signs of imbalance or misalignment. Its robust construction minimizes downtime caused by sensor failure.

Installation & Setup

Proper installation is critical for accurate readings. The probe uses a 3/8-24 UNF thread, so ensure the mounting hole matches this specification. Recommended torque for standard forward-mounted probes is 11.2 N•m (100 in•lbf). For the first three threads, use a lower torque of 7.5 N•m (66 in•lbf). The maximum rated torque is 33.9 N•m (300 in•lbf) for the case and 22.6 N•m (200 in•lbf) for the first three threads. Always follow the manufacturer's guidelines for gap setting and wiring.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended to ensure long-term reliability. Check for physical damage, especially at the tip and cable connection. The probe is designed to withstand harsh environments, but periodic verification of the scale factor is advised. The probe's temperature range allows use in high-heat areas, but exposing it to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Following a routine maintenance schedule helps extend service life and reduce replacement costs.

Compatibility & Integration

The 3300 XL probe works with Bently Nevada extension cables and Proximitor sensors. Field wiring should use 3-conductor shielded triad cable with tinned conductors. Maximum field wiring length between the Proximitor and monitor is 305 meters (1,000 feet). The probe is compatible with standard 3300 XL monitoring systems. For specific integration details, consult the official Bently Nevada documentation.

Troubleshooting & Common Issues

If the probe fails to provide a signal, check the cable connection and ensure proper torque. A common issue is incorrect gap setting, which can be adjusted per the recommended -9 Vdc gap for radial vibration. Another issue is cable damage from excessive pulling; the CableLoc design provides 330 N pull strength, but avoid exceeding that limit. If readings are erratic, verify that the probe tip is clean and free from debris. For persistent problems, contact Petro Auto Tech for technical support.
