Technical Specifications

• Part Number: 330930-065-01-00
• Device Type: Single-channel vibration monitor (velocity/acceleration/displacement)
• Primary Measurement Parameter: Vibration velocity (RMS); selectable acceleration (peak) and displacement (peak-to-peak)
• Measurement Ranges (Configurable): Velocity: 0–65 mm/s RMS (default)
• Acceleration: 0–60 g peak
• Displacement: 0–6 mm peak-to-peak

Function Features

• Extended Velocity Range for Versatile Monitoring: The 0–65 mm/s RMS velocity range bridges the gap between standard low-range (0–50 mm/s) and high-range (0–100 mm/s) monitors, making it ideal for machinery with variable vibration profiles—such as centrifugal pumps, medium-sized turbines, and industrial fans—that operate across mid-to-high vibration levels.
• Tri-Parameter Measurement Capability: Users can switch between velocity, acceleration, and displacement measurements via the front-panel menu, eliminating the need for multiple dedicated monitors. This flexibility simplifies system design and reduces inventory costs, especially in facilities with diverse machinery types.
• High-Precision Sensing & Low Drift: ±0.3% accuracy and temperature-compensated circuitry ensure consistent measurements across operating temperatures, preventing false alarms caused by environmental fluctuations. The 0.01 mm/s resolution captures subtle vibration anomalies that indicate early-stage faults, such as incipient bearing fatigue.
• Configurable Alarm Relays with Diagnostic Feedback: Dual Form C relays support independent high and low alarm thresholds, which can be set via the LCD interface. The monitor provides visual and relay-based feedback for alarm conditions (e.g., overrange, sensor fault), enabling targeted troubleshooting.
• Seamless Integration with Control Systems: RS485 Modbus RTU connectivity allows the monitor to communicate with DCS (e.g., Siemens PCS 7, Emerson DeltaV), SCADA, and predictive maintenance software (e.g., IBM Maximo, GE Predix). The isolated 4–20 mA output ensures noise-free signal transmission to analog control systems.
• Rugged IP65 Enclosure for Harsh Environments: The aluminum alloy housing with IP65 protection resists dust, water spray, and mechanical impact, making it suitable for installation in factory floors, offshore platforms, and mining facilities where environmental conditions are challenging.
• User-Friendly Front-Panel Operation: The backlit LCD and intuitive button interface enable on-site configuration without specialized software. Users can quickly adjust measurement parameters, set alarm thresholds, and view diagnostic data, reducing setup time and maintenance complexity.
• Dual Power Supply Options: Support for both DC and optional AC power inputs adapts to diverse industrial electrical systems, making the monitor suitable for remote locations (DC-powered) and standard factory environments (AC-powered).
• Sensor Fault Detection: The monitor automatically detects sensor disconnections, short circuits, and signal degradation, triggering a dedicated fault alarm to prevent unmonitored operation—a critical safety feature for mission-critical machinery.

Application Scenarios

• Power Generation (Steam & Gas Turbines): Installed in turbine control rooms to monitor bearing vibration. The 65 mm/s range accommodates normal operating vibrations and transient spikes during startup/shutdown, while high precision detects rotor misalignment and blade degradation—key causes of turbine failures.
• Oil & Gas (Pipeline Compressors & Pump Stations): Deployed in onshore and offshore pipeline facilities to monitor centrifugal compressor and process pump vibration. The IP65 enclosure withstands saltwater spray and dust, while Modbus connectivity enables remote monitoring of distributed assets.
• Petrochemical Refining (Catalytic Crackers & Reactors): Used to monitor vibration in catalytic cracker fans and reactor agitators. The tri-parameter capability allows operators to track velocity (normal operation) and acceleration (high-frequency faults), complying with safety regulations for hazardous processes.
• Manufacturing (CNC Machines & Robotic Arms): Installed in automotive and aerospace manufacturing facilities to monitor CNC mill and robotic arm vibration. The high resolution ensures precision machining by detecting tool wear and spindle imbalance, reducing product defects.
• Marine (Ship Propulsion Engines & Auxiliary Pumps): Deployed in ship engine rooms to monitor diesel engine and auxiliary pump vibration. The dual power supply option adapts to marine electrical systems, while the rugged housing withstands shock and vibration from ship movement.
• Mining (Crushers & Conveyor Drives): Used in coal and mineral mining facilities to monitor crusher and conveyor motor vibration. The sensor fault detection feature prevents unmonitored operation in remote mining sites, while the IP65 enclosure resists dust and water ingress.
• Renewable Energy (Wind Turbine Gearboxes): Installed in wind farm nacelles to monitor gearbox vibration. The 65 mm/s range accommodates vibration from variable wind speeds, and Modbus connectivity integrates with wind farm management systems to support predictive maintenance.
• Water & Wastewater Treatment (Large Pumps & Aerators): Deployed in municipal wastewater plants to monitor large pump and aerator vibration. The configurable alarms trigger maintenance before pump failures cause process disruptions, ensuring continuous water treatment operations.
