Bently 330980-50-00

Technical Specifications

• Part Number: 330980-50-00
• Device Type: Multi-function machinery protection monitor (vibration/position/temperature)
• Monitoring Parameters: Primary: Vibration velocity (RMS), vibration acceleration (peak), shaft displacement (peak-to-peak)
• Secondary: Shaft axial position, bearing temperature, rotor speed

Function Features

• Multi-Parameter Integration: Combines vibration, position, temperature, and speed monitoring in one unit, providing a holistic view of machinery health. This eliminates the complexity of integrating multiple single-parameter devices and reduces rack space requirements by up to 60%.
• API 670 Compliance: Meets the rigorous requirements of API Standard 670 for machinery protection systems, making it suitable for critical rotating equipment in oil & gas and petrochemical applications where compliance is mandatory.
• Redundant Power Supply: Dual 24 V DC inputs ensure fault tolerance—if one power source fails, the monitor automatically switches to the backup, preventing unmonitored operation of mission-critical machinery.
• Advanced Alarm Logic: 8 configurable Form C relays support multi-level alarm strategies (warning, high, critical) with time-delayed or latching settings. Users can define custom alarm thresholds for each parameter to align with specific machinery requirements.
• Intuitive Color Touchscreen: 4.3-inch high-resolution touchscreen displays real-time parameter values, alarm status, and trend graphs. The user-friendly interface allows quick configuration, data logging, and troubleshooting without specialized software.
• Comprehensive Data Logging: Built-in non-volatile memory stores up to 10,000 data points per parameter, including alarm events and system diagnostics. Data can be exported via Ethernet or USB for analysis in predictive maintenance software.
• Flexible Communication Options: Ethernet (Modbus TCP/IP) and RS485 (Modbus RTU) enable seamless integration with DCS, SCADA, and IIoT platforms. This supports centralized monitoring of multiple monitors across a facility and remote access to data.
• High-Precision Sensing: ±0.2% accuracy for vibration measurements and ±0.1 °C for temperature ensures reliable data for early fault detection. The monitor captures subtle anomalies like bearing degradation and rotor imbalance before they cause equipment failure.
• Wide Sensor Compatibility: Optimized for Bently Nevada’s 3300 XL sensors but supports third-party RTDs, thermocouples, and encoders, providing flexibility for retrofits and mixed-sensor environments.
• Fault Tolerance & Diagnostics: Built-in self-diagnostics monitor internal components (power supply, CPU, memory) and sensor inputs. The monitor alerts users to sensor faults, communication errors, or internal issues, enabling proactive maintenance.

Application Scenarios

• Oil & Gas (Centrifugal Compressors): Installed in refineries and gas processing plants to protect centrifugal compressors. The monitor tracks vibration (50 mm/s range), bearing temperature, and shaft position, complying with API 670. Redundant power and advanced alarms prevent compressor failures that could disrupt production.
• Power Generation (Steam Turbines): Deployed in coal-fired, gas-fired, and nuclear power plants to monitor steam turbine health. It measures vibration velocity, axial position, and bearing temperature, providing protection against rotor rubs and bearing failures. Ethernet connectivity integrates with plant DCS for centralized control.
• Petrochemical (Reciprocating Pumps): Used to monitor reciprocating pumps in chemical processing facilities. The monitor tracks vibration acceleration (to detect valve wear) and temperature, while speed input ensures alignment with process requirements. API 670 compliance meets safety regulations for hazardous environments.
• Heavy Manufacturing (Large Gearboxes): Installed in steel and aluminum mills to protect large gearboxes used in rolling mills. It monitors vibration velocity (50 mm/s range) and temperature, detecting gear tooth wear and misalignment. The touchscreen interface allows on-site operators to quickly assess gearbox health.
• Marine (Main Propulsion Engines): Deployed in large ships (tankers, container vessels) to monitor main propulsion engines. The monitor tracks vibration, temperature, and speed, providing early warning of engine faults. Redundant power ensures reliable operation at sea, while Modbus RTU enables integration with shipboard control systems.
• Renewable Energy (Wind Turbine Generators): Installed in onshore and offshore wind farms to monitor wind turbine generators. It measures vibration velocity, bearing temperature, and rotor speed, detecting faults in the generator and gearbox. Data logging supports predictive maintenance, reducing wind farm downtime.
• Chemical Processing (Agitators & Mixers): Used to monitor industrial agitators and mixers in chemical plants. The monitor tracks vibration and temperature, ensuring consistent mixing performance and preventing seal failures that could lead to chemical leaks. Configurable alarms align with plant safety protocols.
• Mining (SAG Mills): Deployed in mining facilities to protect semi-autogenous grinding (SAG) mills. The monitor measures vibration velocity (50 mm/s range) and bearing temperature, detecting liner wear and imbalance. The robust aluminum housing withstands dust and vibration in mining environments.
