Configured for vibration signal transmission in Bently Nevada 330400 and 330425 Accelerometer systems, the Bently Nevada 130539-17 (130539-17 3-Conductor Shielded Cable) provides direct electrical connection between acceleration sensors and monitoring equipment through a shielded three-conductor assembly.

Model Configuration Details

The 130539-17 is a dedicated cable assembly for Bently Nevada 330400 and 330425 accelerometers. The assembly includes a 3-socket plug with fluorosilicone elastomer boot at one end and terminal lugs at the opposite end.

The cable design uses 18 AWG (1.0 mm2) conductors with shielding for vibration measurement signal routing. The available cable length range is from 2.0 ft (0.6 m) to 99 ft (30 m).

Hardware Specifications

Machinery Vibration Signal Interface

The 130539-17 cable assembly is configured for casing acceleration measurement circuits associated with Bently Nevada 330400 and 330425 accelerometers. The 330400 model provides a 50 g peak amplitude range with 100 mV/g sensitivity, while the 330425 model provides a 75 g peak amplitude range with 25 mV/g sensitivity.

For vibration monitoring applications, cable shielding helps maintain signal integrity by reducing electrical interference during transmission between the accelerometer and monitoring input interface.

Bently Nevada machinery monitoring systems require correct sensor wiring practices to preserve acceleration signal accuracy. Cable routing, shield termination, and grounding methods directly influence measurement stability.

Rotor Dynamics Signal Considerations

Accelerometer systems differ from eddy-current proximity probe measurement chains because acceleration sensors directly measure casing vibration response rather than shaft displacement. Proper cable installation helps maintain the electrical characteristics required for vibration waveform analysis.

For systems containing multiple vibration measurement channels, correct shielding practices help reduce cross-talk suppression issues between adjacent signal circuits. Cable separation from high-current conductors is recommended to minimize induced noise.
