Function Features

• Dual-Axis Simultaneous Measurement: Captures vibration data in X and Y axes simultaneously, providing a 360° view of machinery health. This eliminates blind spots in monitoring, critical for detecting complex faults like rotor misalignment and shaft bending common in large Chinese industrial pumps and turbines.
• Chinese Market Compliance: Meets CCC certification requirements and GB series standards, ensuring seamless integration into Chinese industrial networks without additional modifications. The EMC design resists interference from high-voltage power grids prevalent in China’s manufacturing hubs.
• Industry-Standard 4-20 mA Output: Dual 4-20 mA channels deliver calibrated data compatible with mainstream Chinese DCS systems (e.g., Sinopec’s SUPCON JX-300X, Huawei’s eLTE Industrial Internet platform). The 4 mA “live zero” design distinguishes between normal operation and power failure, preventing false alarms.
• Flexible Mounting Options: Supports both DIN rail installation (common in Chinese control cabinets) and 10-32 UNF threaded mounting for direct attachment to machinery. Screw terminals accommodate local cable standards, simplifying on-site wiring.
• Proactive Fault Monitoring: Dual fault relays trigger independent alerts for each axis, enabling targeted troubleshooting of issues such as sensor signal loss or excessive vibration. This aligns with China’s “Smart Factory” initiatives by supporting predictive maintenance workflows.
• Wide Voltage Tolerance: The 18-32 V DC supply range accommodates fluctuations in Chinese industrial power systems, ensuring stable performance in remote areas or facilities with inconsistent voltage.
• Flame-Retardant Design: Complies with GB 8624-2012 B1 grade flame resistance, making it suitable for hazardous environments in China’s petrochemical and coal-fired power plants.
• Seamless System Integration: Interfaces directly with Bently 3300 XL monitoring systems and Chinese-made SCADA platforms (e.g., Kingview, Intouch). Optional Modbus RTU communication (via RS485) supports integration into industrial internet of things (IIoT) networks.
• Temperature Adaptability: Operates reliably across China’s diverse climates, from cold northern industrial zones (-20 °C) to hot southern manufacturing facilities (+70 °C), ensuring consistent performance year-round.

Application Scenarios

• Coal-Fired Power Plants (China’s Dominant Power Source): Installed in boiler feedwater pumps, induced draft fans, and turbine generators. Dual-axis monitoring detects bearing wear and rotor imbalance, critical for ensuring continuous operation of coal-fired units that supply over 50% of China’s electricity.
• Petrochemical Industry (China’s Strategic Sector): Deployed in refineries (e.g., Sinopec, PetroChina) for catalytic cracker fans, centrifugal compressors, and pipeline pumps. CCC certification and flame-retardant design comply with safety regulations for handling flammable hydrocarbons.
