Product Description
The 330901-00-40-05-02-05 is a 9 mm (0.35 in) Proximity Transducer Assembly from the Bently Nevada 3300 series. This part number represents a complete, integrated transducer system, which includes a 9 mm eddy current proximity probe, a permanently attached 40-foot cable, and a -05 "California Style" connector. This "Tip-to-Card" design provides a seamless, high-integrity signal path from the probe tip directly to a compatible proximitor (preamplifier) slot in a monitoring rack, eliminating intermediate connection points. It is engineered for high-precision measurement of shaft vibration, position (gap), and speed (Keyphasor®) on large rotating machinery where a 9mm probe is the specified standard.

Application Scenarios
This 9mm transducer assembly is used for critical machinery protection in applications that require a larger probe size and a long cable run for direct connection to a monitoring rack.
Power Generation: Ideal for monitoring steam turbines and gas turbines where the 9mm probe is specified for certain vibration and position measurements. The 40-foot cable provides ample length for routing from the turbine casing to a centrally located monitoring rack.
Oil & Gas: Used on large critical equipment like pipeline compressors and gas turbines. The integrated "California Style" connector offers a reliable, direct interface for rack-based monitoring systems, aiding in compliance with API 670 standards.
Hydroelectric Power Plants: Monitoring large generator shafts and turbines where the 9mm probe's robustness and extensive linear range are advantageous.
Heavy Industry: Protecting large motors, fans, and gearboxes in industries such as mining and metals, where the machinery size warrants a 9mm transducer and signals need to be routed over longer distances.
