Technical Specifications

• Part Number: 330980-71-CN
• Device Type: China-market multi-function machinery protection monitor (vibration/position/temperature/speed/phase)
• Core Monitoring Parameters: Vibration: Velocity (RMS), acceleration (peak), shaft displacement (peak-to-peak), crest factor
• Position: Shaft axial position, radial vibration, differential expansion
• Thermal: Bearing temperature (4 channels), stator temperature
• Mechanical: Rotor speed, phase angle, runout compensation

Function Features

• 71 mm/s Range for China’s Heavy Industry: The 0–71 mm/s RMS velocity range is tailored for high-vibration equipment dominant in China’s industrial sector—such as SAG mills in Inner Mongolia mines, rolling stands in Hebei steel plants, and reciprocating compressors in Sichuan petrochemical facilities. It eliminates range scaling, ensuring maximum resolution for critical fault detection.
• China Standard Compliance & CCC Certification: Meets mandatory CCC certification for electrical safety and GB series standards for vibration measurement and EMC. This ensures seamless integration into Chinese industrial projects without additional testing or modifications, accelerating project commissioning.
• Localized Communication & Sensor Compatibility: Optimized to connect with mainstream Chinese DCS systems (SUPCON JX-300X, Hengyuan HY-SCADA) via customized Ethernet protocols. Compatible with domestic sensors (Sinocera, Xi’an Jiaotong University models) to support cost-effective retrofits in brownfield sites.
• Chinese/English Bilingual HMI: 7-inch touchscreen features intuitive Chinese-English interface switching, supporting on-site operators with localized operation guides and alarm messages. Anti-glare design ensures visibility in bright Chinese factory environments.
• China-Optimized Power Supply: AC input tailored to China’s 220 V AC 50 Hz mains (GB 156-2011) and DC input matching industrial 24 V DC systems. Redundant power ensures uninterrupted operation in areas with unstable power grids, such as rural mining regions.
• Holistic Multi-Parameter Monitoring: Integrates vibration, position, temperature, speed, and phase measurements to enable cross-parameter correlation—critical for diagnosing complex faults in China’s large-scale equipment (e.g., coal-fired power plant turbines, petrochemical compressors).
• Advanced Alarm & ESD Integration: 12 configurable relays support multi-level alarms aligned with Chinese industrial safety protocols (GB/T 28001). Dedicated ESD contacts (≤10 ms response) integrate with plant safety systems to meet emergency shutdown requirements in hazardous areas.
• Data Management for Chinese Smart Factories: Supports GB2312/GBK encoding for data export, ensuring compatibility with domestic MES (Manufacturing Execution System) and IIoT platforms (Huawei Cloud, Alibaba Cloud Industrial Internet). Built-in data logging aligns with China’s “Smart Manufacturing” data collection requirements.
• Harsh Environment Adaptability: IP55 housing and wide temperature range (-20 °C to +80 °C) suit China’s diverse climates—from freezing winters in Northeast China to hot, humid summers in the Yangtze River Delta. Corrosion-resistant housing withstands salt spray in coastal petrochemical plants.
• Runout Compensation & On-Site Calibration: Built-in runout compensation eliminates shaft eccentricity interference, critical for large rotating equipment in China’s steel and power sectors. On-site calibration (via HMI or Chinese-language software) reduces maintenance downtime.
• Redundant & Hot-Swappable Power: Dual isolated power inputs with hot-swappable modules ensure fault tolerance, meeting the high reliability requirements of China’s key energy infrastructure (e.g., national grid power plants, strategic oil pipelines).

Application Scenarios
