Bently Nevada 330104-05-15-05-02-00 3300 XL 8 mm Proximity Probe

Why Do Critical Machines Fail Without Warning?

Unplanned downtime from rotating equipment failures costs industries millions each year. The Bently Nevada 330104-05-15-05-02-00 3300 XL 8 mm Proximity Probe delivers the precise, real-time shaft displacement data needed to detect early signs of vibration or position drift before they escalate into catastrophic breakdowns.

Product Overview

The 330104-05-15-05-02-00 is a 3300 XL 8 mm proximity probe from Bently Nevada, designed for non-contact measurement of shaft radial vibration and axial position in critical rotating machinery. This metric probe features a 50 mm unthreaded length, 150 mm overall case length, and a 0.5 meter (1.6 feet) total length with a miniature coaxial ClickLoc connector and standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the probe case is constructed from AISI 303 or 304 stainless steel (SST) for durability in harsh environments.

Key Technical Specifications

The 330104-05-15-05-02-00 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.45 ± 0.50 Ω for the 0.5 m probe length. The probe case thread is M10x1 with a maximum thread engagement of 15 mm.

Industry Applications

This proximity probe is ideal for monitoring steam turbines, compressors, pumps, and other rotating machinery in power generation, oil and gas, and heavy manufacturing. Its robust design and precise linear range enable accurate vibration and position measurements that help operators schedule maintenance proactively, reducing unplanned downtime and extending equipment life.

Installation and Setup Guidance

Proper mounting is critical for accurate readings. The probe is designed for standard forward mounting with a recommended case torque of 11.2 N•m (100 in•lbf) and a maximum rated torque of 33.9 N•m (300 in•lbf). Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies with longer cable runs.

Maintenance and Reliability

The probe operates reliably in temperatures from -52°C to +177°C (-62°F to +350°F) for standard models, with extended range options available. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe exhibits 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. Regular inspection of the probe tip and cable for physical damage is recommended to ensure consistent performance.

Selection Guide and Purchasing Advice

Before ordering, verify that the 330104-05-15-05-02-00 matches your required thread size (M10x1), cable length, and connector type. This model uses a miniature coaxial ClickLoc connector with standard cable and does not require agency approval (option 00).
