Configured for acceleration signal transmission in Bently Nevada 330400 and 330425 accelerometer systems, the Bently Nevada 130539-20 (130539-20 3-Conductor Shielded Cable) provides direct electrical connection between vibration sensors and monitoring hardware circuits.

Model Identification

The 130539-20 is a three-conductor shielded cable assembly designed for Bently Nevada accelerometer signal wiring. The cable incorporates an 18 AWG (1.0 mm2) shielded conductor structure with a 3-socket plug and fluorosilicone elastomer boot on one end and terminal lugs on the opposite end.

This cable assembly supports casing acceleration measurement applications where vibration signals from 330400 and 330425 accelerometers are transferred to machinery monitoring systems.

Hardware Specifications

Rotor Dynamics Signal Characteristics

The 130539-20 cable is configured for vibration monitoring circuits where acceleration signal quality depends on controlled impedance, shielding performance, and conductor arrangement. The shielded structure supports reduction of external electrical noise coupling during sensor signal transmission.

Within Bently Nevada machinery protection applications, proper accelerometer cabling contributes to accurate rotor dynamics analysis. The cable assembly is associated with casing acceleration measurement circuits used for vibration evaluation, including high-frequency mechanical response monitoring.
