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 Nevada 3500/15 is a high-performance proximity probe system designed for continuous monitoring and protection of rotating machinery in industrial applications. It utilizes eddy current technology to measure the relative displacement of shafts, providing accurate data on vibration, position, and other critical parameters. The system is widely used in turbines, compressors, pumps, and other heavy machinery to detect potential faults, prevent failures, and ensure operational reliability.
Known for its robust design and precision, the 3500/15 integrates seamlessly with the Bently Nevada 3500 series monitoring framework, offering real-time diagnostics and alarm capabilities. Its advanced signal processing ensures minimal interference and high sensitivity, making it a trusted solution for condition monitoring in demanding environments. The system helps industries maintain optimal performance while reducing downtime and maintenance costs.
