Product Introduction
The Bently Nevada 330171-00-30-10-02-00 is a 5mm proximity probe designed for precise vibration monitoring in rotating machinery. This 3300 series probe, made in the USA, features a 1/4-28 UNF thread and a polyphenylene sulfide (PPS) tip. It provides reliable displacement measurements critical for predictive maintenance in turbines, compressors, and pumps.
With a total length of 1.0 meter (3.3 feet) and a miniature coaxial ClickLoc connector, the Bently Nevada 330171-00-30-10-02-00 integrates easily into existing monitoring systems. Its unthreaded length is 0 inches, overall case length is 3 inches, and it requires no agency approval option.

Industry Applications
The Bently Nevada 330171-00-30-10-02-00 shines in vibration monitoring for steam turbines, gas turbines, compressors, and large pumps. Its 5mm sensing range and rugged construction make it ideal for high-temperature environments up to 177°C. In a typical turbine protection system, this probe helps detect shaft radial vibration, preventing catastrophic failures and reducing unplanned downtime.
For angle C (cost-benefit), investing in this OEM-grade probe extends service intervals and ensures accurate data for proactive maintenance, lowering overall operating costs.
Installation & Setup Guidance
When installing the Bently Nevada 330171-00-30-10-02-00, drill and tap a mounting hole for a 1/4-28 thread using a #3 or larger tap drill. Ensure the maximum thread engagement of 0.375 inches is not exceeded to avoid damaging the probe case. Torque the probe case to 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb). For the connector-to-connector torque, do not exceed 0.565 N·m (0.42 ft·lbf). Maintain a minimum cable bend radius of 25.4 mm to preserve cable integrity.
Maintenance & Reliability
Regularly inspect the probe tip and cable for wear or damage. The probe operates reliably from -35°C to +177°C, but avoid exposing it below -34°C as this may cause premature failure of the pressure seal. The gold-plated connectors resist corrosion, and the AISI 304 stainless steel case withstands harsh industrial environments. Routine checks of the probe's DC resistance (7.59 ± 0.50 Ω for 1.0m cable) help confirm proper operation.
Selection Guide & Purchasing Advice
Before purchasing, verify your system's cable length requirement: this unit has a 1.0-meter cable with a miniature coaxial ClickLoc connector. If you need a different length, other options are available in the 3300 family. Ensure your monitor or proximitor is compatible with Bently Nevada sensors.
