Product Description
The 330102-00-24-20-12-05 is an 8 mm Eddy Current Proximity Transducer System component from the Bently Nevada 3300 series. This part number represents a complete transducer assembly, integrating an 8 mm proximity probe, a 24-foot long integral cable, and a -05 "California Style" connector. This "Tip-to-Card" design ensures the probe is perfectly matched to its cable and connector, providing maximum signal integrity and allowing it to plug directly into a compatible proximitor (preamplifier) without the need for a separate junction box. It is engineered for precise measurement of shaft vibration, position, and speed on critical rotating machinery.

Application Scenarios
This transducer assembly is designed for high-reliability monitoring in environments where a direct connection from the sensor to the monitoring rack is required, providing a clean and reliable signal path.
Power Generation: Ideal for monitoring steam turbines and gas turbines in power plants. The 24-foot cable offers ample length for routing from the turbine casing to the monitoring rack, providing essential data on shaft vibration and Keyphasor® timing.
Oil & Gas: Used on critical high-speed equipment like compressors and pumps. The integrated "California Style" connector is a common and reliable interface for rack-based monitoring systems in this industry, helping to meet API 670 standards.
Hydroelectric Power Plants: Monitoring generators and turbines for shaft runout and vibration, where the long cable is advantageous for large machines.
General Heavy Industry: Protecting high-value assets such as large motors and fans where signals are routed directly back to a centralized control room monitoring rack.
