84661-33 | Bently Nevada | Velomitor Interconnect Cable

Bently Nevada is a global leader in industrial asset condition monitoring and protection, specializing in vibration, pressure, and speed measurement solutions for critical machinery. Founded in 1956 by Don E. Bently, the company pioneered eddy-current proximity probes, revolutionizing rotor dynamics monitoring. Acquired by GE in 2002, Bently Nevada operates in over 50 countries, serving industries such as oil & gas, power generation, and mining. Its product portfolio includes sensors, monitoring systems like the 3500 Series, diagnostic instruments, and predictive maintenance software such as System 1. With over 25,000 customers worldwide, the company combines more than 60 years of expertise with cloud-connected solutions to enhance asset reliability and operational safety.

The Bently 84661-33 is a specific length variant within the 84661 series of extension cables manufactured by Bently Nevada This cable serves as a critical link, designed to connect key vibration transducers and speed sensors, such as the 9200 series velocity sensors, to the company's renowned monitoring systems like the 3500 rack or 2300 monitors. Its primary role is to ensure the reliable transmission of vital machine health data from the sensor to the system for analysis.

This particular model is a double-shielded, armored cable engineered for the harsh realities of industrial environments like power generation, oil and gas, and manufacturing plants. It features a robust construction with a twisted pair of 22 AWG conductors, an overall shield for superior protection against electromagnetic interference, and a protective armor layer that guards against physical damage, crushing, and moisture ingress. One end is typically terminated with a sealed, environmentally protected female connector that mates directly with the sensor, while the opposite end is often fitted with terminal lugs for a secure connection to the monitoring system's interface.

The fundamental purpose of the 84661-33 is to accurately carry low-level analog signals over its specific length with maximum integrity and minimal loss or noise. The armored and shielded design ensures signal fidelity is maintained even in areas with high levels of EMI, potential abrasion, and exposure to oils, chemicals, and humidity. These cables are supplied in precise one-foot increments, with the "-33" suffix indicating its unique pre-determined length for specific application requirements.
