Bently Nevada 330104-10-23-10-01-00 3300 XL 8 mm Proximity Probe

Product Overview

When reliable shaft vibration and position monitoring is critical, the Bently Nevada 330104-10-23-10-01-00 delivers precise measurement in demanding industrial environments. This 3300 XL 8 mm proximity probe uses a metric M10x1 thread and includes armor for enhanced durability. Designed for continuous operation, it provides a linear range of 2 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the target, making it ideal for turbomachinery, compressors, and large rotating equipment.

Technical Specifications Breakdown

The 330104-10-23-10-01-00 features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel. Its unthreaded length is 100 mm, overall case length is 230 mm, and total length is 1.0 meter (3.3 feet). The nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms at 1.0 meter. Operating temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F). The probe case thread is M10x1 with a maximum thread engagement of 15 mm.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of rotating shafts in steam turbines, gas turbines, pumps, and motors. Its robust stainless steel case and PPS tip withstand harsh conditions, while the 2 mm linear range captures critical vibration data for predictive maintenance programs. The 330104-10-23-10-01-00 is compatible with Bently Nevada 3300 XL Proximitor sensors and monitoring systems, ensuring seamless integration into existing protection networks.

Installation & Setup Guidance

For radial vibration measurements, set the recommended gap to -9 Vdc (approximately 1.27 mm or 50 mils). Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. Maximum cable length between the probe and monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the target surface is smooth and free of electrical runout for optimal accuracy.

Maintenance & Reliability

The 330104-10-23-10-01-00 requires minimal routine maintenance. Inspect the probe cable and connector periodically for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe is designed for less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days, ensuring stable performance in humid environments.

Buying Guide & Purchasing Advice

Before ordering, verify the unthreaded length (100 mm), overall case length (230 mm), and total length (1.0 meter) match your application requirements. The 330104-10-23-10-01-00 uses a miniature coaxial ClickLoc connector with connector protector and standard cable.
