Main Features and Advantages
The Bently Nevada AMS3120-A3120/022-000 offers several key features that make it an essential component for machinery protection. Its most significant advantage is its ability to provide continuous, high-speed monitoring of machine vibration. By constantly measuring and analyzing vibration data, the module can detect subtle changes that indicate a developing fault, such as shaft misalignment or imbalance, long before it leads to a major failure. This allows operators to take corrective action in a timely manner, reducing the risk of unplanned downtime. The AMS3120-A3120/022-000 is highly configurable, with adjustable alarm and danger setpoints. This flexibility allows the module to be tailored to the specific characteristics and operating limits of a wide range of machinery.
Integrated Protection: The monitor’s primary function is to provide protection. It has built-in relay outputs that can be wired to a plant’s distributed control system (DCS) or safety shutdown system. When a vibration level exceeds a pre-defined threshold, the relay contacts change state, initiating an alarm or a trip sequence. This robust and reliable protection function is vital for safeguarding critical assets. The Bently Nevada AMS3120-A3120/022-000 is also designed for high reliability, featuring a robust, solid-state design with no moving parts, which ensures a long service life in harsh industrial environments. Its proven performance and trusted brand name make it a reliable choice for machine protection systems.
Application Field
The Bently Nevada AMS3120-A3120/022-000 is a cornerstone of machinery protection in a variety of industries where asset integrity and operational safety are paramount. Its primary application fields are in power generation, oil and gas, and petrochemicals. In power plants, the AMS3120-A3120/022-000 is used to monitor the vibration of large steam and gas turbines, generators, and boiler feed pumps. In the oil and gas sector, it protects critical assets like compressors, pumps, and fans on offshore platforms and in refineries. The module’s ability to detect faults such as high shaft vibration, eccentricity, and axial position provides an early warning system that can prevent catastrophic failures. The monitor is also used in other industries with large rotating equipment, such as pulp and paper and chemical processing. The robust design of the Bently Nevada AMS3120-A3120/022-000 ensures it can withstand the demanding conditions of these environments.

The AMS3120-A3120/022-000 is a module that slides into its designated slot in the rack. Once installed, the sensor cables for the proximity probes or other transducers are connected to the terminal blocks at the back of the rack. The monitor’s alarm and trip outputs are then wired to the plant’s control system. The configuration of the module’s alarm thresholds and other parameters is performed via the configuration software.
Maintenance recommendations: Routine maintenance for the AMS3120-A3120/022-000 is minimal due to its durable solid-state design. The primary maintenance tasks involve periodically checking the sensor cables and connectors for any signs of wear or damage. The monitor has built-in diagnostics that will report any internal faults, ensuring continuous and reliable operation. In the event of a fault, the entire module is typically replaced. It is crucial to ensure that the control cabinet is well-ventilated to maintain the ambient temperature within the specified operating range, which is critical for the long-term health of the electronics.
