Configured for acceleration signal transmission in Bently Nevada 330400 and 330425 Accelerometer systems, the Bently Nevada 130539-50 (130539-50 3-Conductor Shielded Cable) provides direct electrical connection between accelerometer sensors and machinery monitoring interfaces.

Model Configuration Details

The 130539-50 is a three-conductor shielded cable assembly designed for Bently Nevada 330400 and 330425 accelerometer installations. The cable includes a 3-socket plug with fluorosilicone elastomer boot at one end and terminal lugs at the opposite end.

The cable uses 18 AWG (1.0 mm2) conductors with a shielded construction. The available cable length range is from 2.0 ft (0.6 m) to 99 ft (30 m), supporting flexible installation between vibration sensors and monitoring equipment.

Hardware Specifications

Acceleration Signal Transmission Characteristics

The 130539-50 cable transfers acceleration measurement signals from Bently Nevada 330400 and 330425 accelerometers to machinery monitoring systems. The shielded three-conductor structure maintains the electrical connection required for vibration signal acquisition.

The 330400 accelerometer 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. The cable assembly supports these sensor configurations through the specified electrical interface.

Machinery Monitoring Signal Integrity

The shielded cable construction reduces electromagnetic interference during vibration signal transmission. Correct cable installation supports accurate casing acceleration measurement and minimizes external electrical noise influence.

For machinery vibration systems, cable routing and grounding practices affect measurement quality. The cable should be installed separately from high-current conductors to reduce signal disturbance.

Rotor Dynamics Measurement Application

Accelerometer-based monitoring evaluates casing vibration response generated by rotating equipment operation. Unlike eddy-current proximity systems that measure shaft displacement, accelerometers provide acceleration waveform information from machine housings.

Proper cable shielding and connector installation help maintain channel separation and reduce cross-talk effects when multiple vibration measurement points are installed.
