Product Introduction
In critical rotating machinery vibration monitoring, the Bently Nevada 330171-00-26-10-02-00 delivers reliable non-contact displacement measurements. This 3300 series 5mm probe, with 1/4-28 UNF thread and without armor, measures shaft vibration and position in turbines, compressors, and pumps. The miniature coaxial ClickLoc connector ensures a secure and durable connection, while the PPS tip and AISI 304 stainless steel case provide robust and long-lasting performance.
Technical Specifications Breakdown
The 330171-00-26-10-02-00 operates with a power supply requirement of -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Its output sensitivity is less than 2 mV change per volt change in input voltage, and the output resistance is 50 W. The probe DC resistance for a 1.0 meter length is 7.59 ± 0.50 Ω. The probe case material is AISI 304 stainless steel, and the probe tip material is polyphenylene sulfide (PPS). The probe case thread is 1/4-28 with a maximum thread engagement of 0.375 in. Key torque values: probe case torque recommended at 5.1 N·m and maximum at 7.3 N·m, connector-to-connector torque maximum at 0.565 N·m. The probe temperature range is -35°C to +177°C. The weight is 0.323 kg.
Industry Applications
This probe is ideal for turbine shaft vibration monitoring, compressor clearance measurement, and pump bearing position sensing. In each application, the Bently Nevada 330171-00-26-10-02-00 provides accurate and stable readings, mitigating common failure modes such as probe tip wear or incorrect gap through its PPS tip and precise thread engagement guidelines. The 1.0 meter total length suits many OEM installations.
Installation & Setup Guidance
Mounting requires a 1/4-28 tapped hole. Use a #3 or larger tap drill to ensure proper alignment. Maximum thread engagement is 0.375 in. Torque the probe case to 5.1 N·m (recommended), not exceeding 7.3 N·m. Ensure the cable bend radius is at least 25.4 mm to avoid damage. The miniature coaxial ClickLoc connector provides a secure and vibration-resistant connection.
Maintenance & Reliability
Regularly inspect the probe tip and cable for wear and damage. Operate within the rated temperature range of -35°C to +177°C. Avoid prolonged exposure below –34°C to prevent premature failure of the pressure seal. The robust AISI 304 stainless steel case and 222 N tensile strength connectors ensure long service life and reliable performance in demanding environments.
Selection Guide & Purchasing Advice
Before purchasing, verify compatibility with your Proximitor and extension cable. The Bently Nevada 330171-00-26-10-02-00 is a genuine OEM part with total length 1.0 meter and connector option 02 (miniature coaxial ClickLoc). PLC Source PRO offers this probe with fast shipping and assured authenticity. Confirm your system’s thread requirement (1/4-28) and agency approval needs (this unit does not require one).
