Bently Nevada 330104-05-13-10-02-00 3300 XL 8 mm Proximity Probe, Metric

Product Overview

As industrial machinery evolves toward higher speeds and tighter tolerances, the need for precise, non-contact measurement of shaft vibration and position has never been greater. The Bently Nevada 330104-05-13-10-02-00, part of the 3300 XL 8 mm Proximity Probes series, addresses this challenge directly. Engineered for continuous monitoring in rotating equipment such as turbines, compressors, and pumps, this probe delivers accurate displacement data even in extreme conditions. With a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, it withstands temperatures from -52°C to +177°C and resists moisture and chemical exposure.

Technical Specifications Breakdown

The 330104-05-13-10-02-00 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). Its nominal probe DC resistance is 7.59 ± 0.50 ohms at 1.0 meter length. The probe case thread is M10 x 1 with a maximum thread engagement of 15 mm. For installation, the recommended case torque is 11.2 N·m (100 in·lbf), with a maximum rated torque of 33.9 N·m (300 in·lbf). Field wiring supports 0.2 to 1.5 mm² (16 to 24 AWG) conductors, and the maximum cable length between the probe and the 3300 XL Proximitor Sensor is 305 meters (1,000 feet).

Industry Applications

In power generation, the 330104-05-13-10-02-00 monitors turbine shaft vibration to prevent catastrophic failures. In oil and gas, it tracks compressor rotor position, ensuring safe operation under high pressure and temperature. The probe's ability to seal differential pressure between tip and case, using a Viton® O-ring, makes it suitable for applications where process fluids or gases could otherwise damage the sensor. For these critical assets, the probe's robust design reduces unplanned downtime and extends maintenance intervals, directly improving operational ROI.

Installation and Setup Guidance

Proper mounting is essential for accurate readings. The probe should be installed with the recommended torque of 11.2 N·m (100 in·lbf) to avoid damaging the threads or the probe case. Use a 3-conductor shielded triad cable for field wiring, and ensure the total cable length does not exceed 305 meters (1,000 feet) to maintain signal integrity. The probe's linear range begins at 0.25 mm (10 mils) from the target; set the gap to achieve -9 Vdc for radial vibration measurements. Always verify that the probe tip material (PPS) is compatible with the target surface and environmental conditions.

Maintenance and Reliability

The 330104-05-13-10-02-00 requires minimal routine maintenance due to its sealed construction and corrosion-resistant materials. However, periodic inspection of the cable and connector for wear or damage is recommended. The probe operates reliably in relative humidity up to 93% with less than a 3% change in Average Scale Factor (ASF) when tested per IEC standard 68 2 3 for up to 56 days. For extended temperature range applications, the probe tip can withstand up to +218°C and the cable up to +260°C. Exposing the probe to temperatures below -34°C may cause premature failure of the pressure seal, so avoid such conditions.

Compatibility and Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive installations per drawing 140979, it qualifies for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. These certifications allow integration into hazardous area applications across petrochemical, pharmaceutical, and other process industries.

Selection Guide and Purchasing Advice

Before ordering, verify that the probe's unthreaded length (50 mm), overall case length (130 mm), and total length (1.0 meter) match your application requirements. The Miniature ClickLoc coaxial connector option (code 02) provides a secure, quick-connect interface. If agency approval is needed, confirm the option code; this unit is specified as "00 = Not required."
