330101-00-10-10-02-05 | Bently Nevada 8 mm Probe, 1.0 m Cable

Introduction to the 330101-00-10-10-02-05

When machinery vibration threatens uptime, the 330101-00-10-10-02-05 provides precise displacement measurement. This Bently Nevada 3300 XL 8 mm probe features a 3/8-24 UNF thread and a 1.0 meter cable. It is designed for robust performance in industrial environments. The probe comes without armor and includes miniature coaxial ClickLoc connector. It also carries CSA, ATEX, and IECEx approvals for hazardous area use.

Key Features and Technical Specifications

• Probe Type: 3300 XL 8 mm probe, 3/8-24 UNF thread, without armor.
• Total Length: 1.0 meter (3.3 feet).
• Connector: Miniature coaxial ClickLoc connector, standard cable.
• Agency Approvals: CSA, ATEX, IECEx.
• 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% for standard 1 meter system.
• Probe Tip Material: Polyphenylene sulfide (PPS).
• Probe Case Material: AISI 303 or 304 stainless steel.

A standout spec is the patented TipLoc molding method. It creates a more robust bond between probe tip and body. This reduces failures from mechanical stress. The CableLoc design provides 330 N (75 lbf) pull strength. It securely attaches the probe cable and tip. These features enhance reliability in harsh conditions.

Real-World Applications

Engineers use the 330101-00-10-10-02-05 for radial vibration monitoring in rotating machinery. It excels in turbines, compressors, and pumps. The 8 mm probe offers thicker encapsulation of the probe coil in molded PPS plastic. This results in a more rugged probe. It withstands physical abuse better than smaller probes. The larger diameter probe body provides a stronger, more robust case. This makes it ideal for demanding environments.

Installation and Setup

Mount the probe with a 3/8-24 UNF thread. The maximum thread engagement length is 0.563 inches. For standard forward mounted probes, the recommended torque is 11.2 N·m (100 in·lbf). For the first three threads, use 7.5 N·m (66 in·lbf). Field wiring uses 0.2 to 1.5 mm² (16 to 24 AWG) wire. Bently Nevada recommends a 3-conductor shielded triad cable. Maximum field wiring length is 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. Refer to the frequency response graphs for signal rolloff at high frequencies with longer wiring.

Maintenance and Reliability

Regular inspection of the probe and cable is essential. Check for signs of wear or damage. The probe is designed to seal differential pressure between tip and case. The sealing material is a Viton O-ring. Probes are not pressure tested before shipment. Contact Bently Nevada if a pressure seal test is required. The probe operates reliably in humidity up to 93% with less than 3% change in Average Scale Factor.

Compatibility and Integration

The 330101-00-10-10-02-05 works with Bently Nevada 3300 XL extension cables and Proximitor sensors. It is compatible with standard monitoring systems. The miniature coaxial ClickLoc connector ensures secure signal transmission. Use with 3300 XL systems for seamless integration.
