Bently Nevada 330104-00-08-50-02-00 3300 XL 8 mm Proximity Probe

Product Overview: The Bently Nevada 330104-00-08-50-02-00

When your machinery requires precise shaft vibration and position monitoring, the Bently Nevada 330104-00-08-50-02-00 3300 XL 8 mm Proximity Probe delivers reliable performance. This metric probe features an M10 x 1 thread with armor, an 80 mm overall case length, and a 5.0 meter (16.4 feet) total length. It uses a miniature coaxial ClickLoc connector with standard cable and is designed for use with the 5 meter Proximitor sensor only. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST).

Key Technical Specifications

Understanding the specifications helps you match this probe to your application. The 330104-00-08-50-02-00 offers a linear range of 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending from 0.25 to 2.3 mm (10 to 90 mils), corresponding to approximately –1 to –17 Vdc. The recommended gap setting for radial vibration is –9 Vdc, approximately 1.27 mm (50 mils). The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 8.73 ± 0.50 ohms for the 5.0 m probe length. Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG) with a maximum length of 305 meters (1,000 feet) between the Proximitor sensor and the monitor.

Environmental Durability and Temperature Range

This probe handles demanding environments. The standard probe operates and stores from –52°C to +177°C (–62°F to +350°F). An extended temperature range probe is available for the probe tip from –52°C to +218°C (–62°F to +425°F) and for the cable and connector from –51°C to +260°C (–60°F to +500°F). Exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. The probe also shows less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days.

Industry Applications and Use Cases

This proximity probe is ideal for monitoring radial vibration and axial position in rotating machinery such as turbines, compressors, pumps, and motors. Its 2 mm linear range and –9 Vdc recommended gap setting provide accurate, repeatable measurements for predictive maintenance programs. The robust stainless steel case and PPS tip withstand harsh industrial conditions, making the 330104-00-08-50-02-00 suitable for oil and gas, power generation, and manufacturing plants.

Installation and Setup Considerations

Proper installation ensures optimal performance. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Use three-conductor shielded triad cable with tinned field wiring. For best frequency response, keep field wiring under 305 meters (1,000 feet). The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, but it is not pressure tested before shipment. Contact the custom design department if pressure seal testing is required.

Selection Guide and Purchasing Advice

Before ordering, verify that the 330104-00-08-50-02-00 matches your system requirements. This 5-meter probe works exclusively with the 5 meter Proximitor sensor. Confirm the unthreaded length (0 mm), overall case length (80 mm), and total length (5.0 m) fit your installation. The connector option is miniature coaxial ClickLoc with standard cable. Agency approval is not required for this configuration.
