3500/94M 184826-01B Bently Nevada Control Unit

Product  Description：

• • • The Bently Nevada 3500 system is a modular, rack-based platform designed to protect critical machinery in industries such as oil and gas, power generation, and chemical processing. It consists of a power supply, a Rack Interface Module (RIM), various monitoring modules, and a backplane that facilitates communication and power distribution. The system is designed to meet the requirements of the American Petroleum Institute (API) 670 standard for machinery protection systems, making it the benchmark for reliability and performance in harsh industrial environments.

      Product Parameters

      The 3500 system is defined by its flexible architecture and diverse module options. A standard full-size rack typically features 14 available slots for monitoring modules, while a mini-rack offers 7 slots. The system operates with dual redundant power supplies to ensure uninterrupted monitoring even if one power source fails. It supports a wide variety of inputs, including Proximity Probes, Accelerometers, Velomitors, RTDs, and Thermocouples. For output and communication, the system provides dedicated relay modules for trip signals and the Transient Data Interface (TDI) for high-speed data transfer to System 1 software. It typically requires 24 VDC, 115 VAC, or 230 VAC power inputs depending on the selected power supply module.

      Product Advantages

      One of the primary advantages of the Bently Nevada 3500 is its unparalleled reliability and safety certification, as it is frequently SIL 2 rated, making it suitable for Safety Instrumented Systems (SIS). Its modular design allows users to customize the rack to their specific needs and easily expand the system as more machinery points require monitoring. The system provides enhanced diagnostics by capturing both steady-state and transient data (such as startup and shutdown sequences), which is critical for identifying root causes of machinery issues. Furthermore, the redundant architecture—covering power supplies, communications, and relays—minimizes the risk of false trips and ensures the protection system remains online during maintenance or single-point failures.

      Important Considerations and Precautions

      When installing and operating the 3500 system, several precautions must be observed to ensure longevity and accuracy. Proper grounding is essential to prevent electrical noise from interfering with sensitive vibration signals. The system should be installed in an environmentally controlled enclosure if the ambient conditions exceed the specified operating temperature or involve corrosive gases. Users must also ensure that the Rack Configuration Software is used correctly to set alarm and danger setpoints, as incorrect configuration can lead to either unprotected machinery or unnecessary production downtime. Additionally, electrostatic discharge (ESD) protection should be utilized whenever handling or replacing modules to prevent damage to the internal circuitry.

      Product Applications

      The 3500 Control Unit is applied to a vast range of critical industrial machinery where a failure could result in significant financial loss or safety hazards. Typical applications include Gas Turbines and Steam Turbines used in power plants, Centrifugal and Axial Compressors in refineries and chemical plants, and Large Pumps and Electric Motors used in water treatment or mining operations. It is also used extensively for Hydroelectric Turbines, Gearboxes, and Fans. By monitoring parameters like radial vibration, axial thrust, eccentricity, and temperature, the system protects these assets from catastrophic failure while providing the data necessary for a comprehensive condition-based maintenance strategy.
