Configured for acceleration signal transmission between Bently Nevada accelerometers and monitoring circuits, the Bently Nevada 130539-30 (130539-30 Interconnect Cable) provides direct electrical connection for 330400 and 330425 vibration measurement systems.

Model Identification

The 130539-30 is a three-conductor shielded interconnect cable assembly designed for Bently Nevada accelerometer installations. The cable uses 18 AWG (1.0 mm2) conductors with a 3-socket plug and fluorosilicone elastomer boot at one end and terminal lug termination at the other end.

The cable assembly supports connection between accelerometer field sensors and vibration monitoring equipment where casing acceleration signals require controlled transmission characteristics.

Hardware Specifications

Rotor Dynamics Signal Transmission Characteristics

The 130539-30 cable assembly is designed for vibration monitoring signal paths where shielding, impedance control, and conductor configuration influence measurement accuracy. The shielded construction supports suppression of external electrical interference affecting acceleration signal transmission.

For Bently Nevada machinery monitoring systems, correct cable installation assists rotor dynamics evaluation by maintaining the electrical characteristics between the accelerometer and monitoring input channel. The cable is associated with casing acceleration measurement circuits used with 330400 and 330425 accelerometer platforms.
