Bently Nevada 3500/62 Process Variable Monitor

Function Features

• Diversified Input Adaptability: It provides three types of I/O module options, namely ±10 volts DC, isolated 4 – 20 mA, and 4 – 20 mA with intrinsically safe zener barriers. The internal barrier I/O is equipped with external power input terminals to supply intrinsically safe power to 4 – 20 mA transducers, adapting to different field sensor signal requirements.
• Flexible Alarm Configuration: Users can set alert and danger setpoints within 0 – 100% of the full – scale range for each measured parameter. It also has both under and over alarm setpoints. If the full – scale range exceeds the sensor range, the setpoints will be limited to the sensor’s applicable range, which effectively adapts to different equipment protection needs.
• Triple Modular Redundant Compatibility: It can be deployed in triple modular redundant configurations. The adjacent installation of three monitors and the adoption of voting logic greatly improve the stability and reliability of the monitoring system, which is suitable for safety – critical industrial scenarios.
• Seamless System Integration: It can be programmed through 3500 rack configuration software and occupies one slot in the 3500 series rack. It can seamlessly integrate external process parameters into the condition monitoring system to achieve unified management and integrated control of monitoring data.
• Clear Status Feedback: The two front – panel LED indicators clearly reflect the module’s working state. The OK LED lights up when the module operates normally, and the TX/RX LED indicates whether the module is communicating with other modules in the 3500 rack, which helps maintenance personnel quickly identify faults.

Function Features

• Multi – parameter Integrated Monitoring: It can uniformly monitor multiple critical process variables such as pressure, flow, temperature, and liquid level. It centralizes the signals of different types of sensors, which eliminates the need for multiple independent monitoring devices and simplifies the on – site equipment layout.
• Reliable Signal Conditioning: It can effectively condition the received 4 – 20 mA current signals and ±10 VDC voltage signals. It filters and stabilizes the interference – prone signals in industrial environments to ensure the accuracy and stability of the measured data.
• Intrinsic Safety Support: The I/O module with intrinsically safe zener barriers meets the safety requirements of flammable and explosive industrial environments. It provides safe power supply for transducers and prevents potential safety hazards caused by electrical sparks.
• Convenient Programming and Configuration: Through the 3500 rack configuration software, users can easily program the module to switch between current and voltage measurement modes. The operation process is simple, which can quickly adapt to the changes of on – site monitoring requirements.
• Strong Interoperability: It supports integration with SCADA systems and distributed control systems via Modbus communication protocol. It realizes the seamless circulation of monitoring data between the module and the upper – level system and reduces the cost of system integration.

Application Scenarios

• Power Generation Industry: It is installed on steam turbines, water turbines, and generator sets. It monitors parameters such as the oil pressure of the lubrication system, the cooling water flow, and the bearing temperature. It triggers alarms in time when parameters are abnormal to avoid equipment damage and ensure the continuous and stable operation of power generation equipment.
• Oil and Gas Industry: It is used in natural gas compressors, oil pipeline pumps, and offshore oil drilling platforms. It monitors the pipeline pressure, medium flow rate, and equipment cylinder temperature in flammable and explosive environments. The intrinsic safety design and redundant configuration ensure the safety of oil and gas extraction and transportation processes.
• Petrochemical Industry: It is applied to reactors, distillation towers, and chemical pumps in petrochemical plants. It tracks parameters such as the reaction pressure in the reactor, the flow rate of the feed liquid, and the temperature of the heat exchanger. It ensures that the production process meets the set standards and prevents safety accidents such as material leakage caused by parameter deviations.
• Marine and Offshore Industry: It is integrated into the monitoring system of marine power equipment and offshore industrial facilities. It monitors the operating parameters of marine engines, pumps, and other equipment. It resists the harsh marine environment with high humidity and salt fog and guarantees the reliable operation of marine equipment during navigation.
• General Manufacturing Industry: It is deployed in papermaking, mining, and other fields. It monitors the hydraulic pressure of mining machinery, the pulp flow in papermaking equipment, and the bearing temperature of transmission gearboxes. It provides data support for predictive maintenance and reduces the downtime caused by unexpected equipment failures.
