• Cable Length: 0.5 meter (1.6 feet) standard cable with miniature coaxial ClickLoc connector.
• Linear Range: 2 mm (80 mils) from approximately 0.25 mm (10 mils) to 2.3 mm (90 mils) from target.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% 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 from -52°C to +177°C (-62°F to +350°F).
• Recommended Gap Setting for Radial Vibration: -9 Vdc (approximately 1.27 mm or 50 mils).

The patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength for robust cable attachment.

Applications and Use Cases

In industrial environments, the 330101-00-12-05-02-00 excels at monitoring shaft vibration and position in turbines, compressors, and pumps. Its 8 mm diameter offers thicker encapsulation for improved ruggedness. For example, in a steam turbine train, this probe helps detect early bearing wear, reducing unplanned downtime.

Installation and Setup

Mount the probe using the 3/8-24 UNF thread into a compatible mounting block. Ensure the target surface is clean and within the linear range of 0.25 mm to 2.3 mm. Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor and monitor. Set the initial gap to -9 Vdc for radial vibration measurements.

Maintenance and Reliability

Regularly inspect the probe cable and connector for wear. The stainless steel case resists corrosion in harsh environments. For extended temperature applications, the probe tip can withstand up to +218°C (+425°F). Follow Bently Nevada's guidelines for periodic calibration verification.

Compatibility and Integration

The 330101-00-12-05-02-00 works with Bently Nevada 3300 XL Proximitor sensors and monitors. It supports standard 5 or 1 meter system configurations. The miniature coaxial ClickLoc connector ensures secure signal transmission.
