Product Performance
Dual-channel independent monitoring design, capable of connecting two sets of sensors for parallel analysis, greatly improving the coverage and efficiency of rotating equipment vibration monitoring
Adopts 16-bit ADC high-precision analog-to-digital conversion, with measurement accuracy up to ±0.5% full scale, excellent data repeatability, suitable for micrometer-level vibration detection needs
Wide frequency range covering 5-1600Hz, taking into account low-frequency shaft vibration and high-frequency bearing fault characteristic signals, which can accurately capture potential equipment fault hazards
Integrates multiple types of signal output and communication interfaces, supporting standard analog signals, alarm relays and fieldbus communication, seamlessly adapting to DCS and PLC systems
Built-in complete self-test function and password protection mechanism, which can real-time monitor the working status of modules and sensors, and feed back fault information in a timely manner, improving system reliability
Supports on-site programmability, parameter configuration such as range, alarm point and filter can be completed through front panel buttons or software tools without disassembly, facilitating operation and maintenance
Wide operating temperature range of -20℃-70℃ combined with modular aluminum housing design, strong vibration and shock resistance, adaptable to complex and harsh industrial working conditions
Supports redundant power input and hot-swapping operation, ensuring that monitoring is not interrupted during equipment maintenance and replacement, and guaranteeing continuous system operation
