Bently Nevada 330171-00-12-05-02-CN Proximitor Transducer System – 3300 XL 8mm Series
When a critical rotating machine loses its shaft proximity monitoring capability, the consequences cascade rapidly: vibration data goes blind, protection systems lose their primary input, and plant operators face an impossible choice between running blind or initiating an unplanned shutdown. In high-stakes environments — turbines, compressors, pumps, and generators — every minute of unmonitored operation is a liability. The Bently Nevada 330171-00-12-05-02-CN Proximitor Transducer System exists precisely to prevent that scenario, delivering continuous, high-accuracy eddy-current proximity measurement that keeps your machinery protection system fully informed at all times.
The 330171-00-12-05-02-CN is a factory-configured transducer system within Bently Nevada’s globally trusted 3300 XL 8mm Series — the industry benchmark for shaft vibration and position measurement in turbomachinery. This specific configuration (12-inch extension cable, 5-meter armored cable, 02 connector type, CN revision) is engineered for installations requiring a compact probe-to-Proximitor interface with robust cable protection in harsh industrial environments. Deployed across refineries, power generation facilities, and petrochemical plants on every continent, the 3300 XL platform is recognized by API 670 as the de facto standard for machinery protection transducer systems.

Frequently Asked Questions
Q: What does the “-CN” suffix mean in part number 330171-00-12-05-02-CN?
A: The “-CN” designates a specific revision or configuration variant within the 330171 product family, typically indicating a regional or application-specific modification to the standard build. Always specify the full part number including suffix when ordering to ensure exact replacement.
Q: Is the 330171-00-12-05-02-CN compatible with Bently Nevada 3500 series monitors?
A: The 330171 series is natively designed for the 3300 XL monitor platform. While the eddy-current output signal is electrically compatible with some 3500 series inputs, we recommend confirming compatibility with your specific 3500 monitor model before installation. Contact our technical team for assistance.
Q: Can you supply the complete transducer system including probe, extension cable, and Proximitor as a matched set?
A: Yes. The 330171-00-12-05-02-CN is supplied as a factory-matched system. All three components (probe, extension cable, Proximitor) are calibrated together and should not be mixed with components from other serial number sets.
Q: What is the typical lead time for this part?
A: Lead time varies by current stock availability. Please submit an RFQ and our team will provide a confirmed delivery schedule within 24 hours.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoice, packing list, certificate of origin, and can arrange third-party inspection certificates upon request.
