GE / Bently Nevada 2789-144 Standard Extension Cable

The GE / Bently Nevada 2789-144 is a standard extension cable that connects proximity transducers to monitoring equipment within the 3300 XL 8 mm proximity transducer system. It enables vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements for machinery protection. The cable facilitates critical signal transmission between transducers and acquisition hardware while maintaining signal integrity in demanding industrial environments. Manufactured in the U.S.A., the 2789-144 is part of a system fully compliant with API 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability.

## Technical Specifications

• **Cable Length:** 12 feet (3.65 m)
• **System Component:** Designed for 3300 XL 8 mm proximity transducer systems
• **Connector Type:** Standard cable without connector protector
• **Shipping Weight:** 2 kg
• **Origin:** Made in U.S.A.

## Key Features

• Signal transmission output directly proportional to distance between probe tip and conductive surface
• Full interchangeability with other 3300 XL probes, extension cables, and Proximitor sensors—no matching or bench calibration required
• Backward-compatible with non-XL 3300 series 5 mm and 8 mm transducer system components
• Compatible with 3300 5 mm probes for applications where 8 mm probes exceed space constraints

## Typical Applications

• Vibration monitoring on fluid-film bearing machinery
• Absolute and relative position measurement
• Keyphasor and machine speed reference signals
• Continuous machinery protection and condition monitoring

## Compatibility & Integration

The 2789-144 functions as a core element within the Bently Nevada 3300 XL 8 mm system architecture. Probes, extension cables, and Proximitor sensors interchange without component matching, streamlining installation and inventory management. The 3300 XL series maintains backward compatibility with earlier non-XL 3300 series configurations, supporting both 5 mm and 8 mm transducer implementations.
