Bentley Nevada (Bently Nevada) 3500 series online monitoring and protection system. Monitoring and protection system for your unit equipment to provide continuous online status monitoring and protection. The Bentley 3500 system works well with the Bentley vibration sensor probe and can accept Bentley converging eddy current sensors, velocity acceleration sensors (e.g. 330400 330500) and various composite sensors. It is a world leader in detecting and preventing false trips and false trips of rotating machinery. More than 80,000 units installed worldwide provide automatic protection values through trip monitoring machines to prevent costly damage when needed. The 3500 system also protects your machines and processes against errant trips that can cause your operations to stop for no reason, resulting in costly outages or lost production. When connected to System 1* software, it also provides continuous condition monitoring information for active maintenance planning. The 3500 system combines the industry’s broadest selection of mechanical measurement parameters with software configurations for nearly all mechanical monitoring scenarios. The 3500 system fully complies with API670 requirements for this class of systems. It is the most powerful and flexible system in the traditional Bentley Nevada frame system, with a variety of features and advanced functions not available to other systems.
