Bently Nevada 330104-02-19-10-01-00 3300 XL 8 mm Proximity Probe Metric

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-02-19-10-01-00 delivers reliable, high-precision measurement. This 3300 XL 8 mm proximity probe, metric version, is engineered for continuous monitoring of shaft vibration and position in critical rotating equipment. Its robust design includes an M10x1 threaded case with armor, making it suitable for harsh industrial environments.

Key Technical Specifications

The 330104-02-19-10-01-00 features a polyphenylene sulfide (PPS) probe tip and a case made of AISI 303 or 304 stainless steel. It 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, corresponding to about 1.27 mm (50 mils). Nominal probe DC resistance is 7.59 ± 0.50 ohms for the 1.0 meter length. The probe operates in temperatures from -52°C to +177°C (-62°F to +350°F) for standard versions, with extended range options available for the tip and cable.

Industry Applications

This proximity probe is ideal for monitoring steam turbines, compressors, pumps, and fans in power generation, oil and gas, and manufacturing. Its high-temperature tolerance and stainless steel construction ensure reliable performance in environments where heat and corrosion are concerns. The 330104-02-19-10-01-00 provides accurate displacement data to help prevent catastrophic failures and reduce unplanned downtime.

Installation and Setup Guidance

For optimal performance, mount the probe with a maximum thread engagement of 15 mm. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG), preferably a three-conductor shielded triad cable with tinned ends. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to the frequency response graphs for signal rolloff at high frequencies when using longer wiring. Set the initial gap to -9 Vdc for radial vibration measurements.

Maintenance and Reliability

Routine inspection of the probe and cable is recommended to verify mechanical integrity and electrical continuity. The probe is designed to seal differential pressure between tip and case using a Viton O-ring, but it is not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe tip material (PPS) resists many chemicals, while the stainless steel case provides durability.

Compatibility and Integration

The 330104-02-19-10-01-00 works seamlessly with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. It supports intrinsically safe installations when used with approved zener barriers (drawing 141092) or galvanic isolators, achieving Class I, Zone 0 ratings. For non-incendive circuits, refer to drawing 140979. Always verify compatibility with your existing system before ordering.

Selection Guide and Purchasing Advice

Before purchasing, confirm that the probe length, thread type, and connector match your application. The 330104-02-19-10-01-00 includes a miniature coaxial ClickLoc connector with connector protector and standard cable. Agency approval is not required for this variant.
