Core Features
The device has four core functions and excels in the field of industrial monitoring and protection. In terms of high-precision vibration monitoring, it supports 0.5Hz~20kHz wide-band vibration analysis, uses 16-bit ADC to achieve ±0.1% full-scale accuracy, can synchronously collect vibration, phase, and speed signals, and automatically calculate peak, effective value, kurtosis and other indicators, accurately matching bearing defect frequencies (such as BPFO/BPFI); in terms of mechanical protection and early warning functions, it is equipped with 4 independent relay outputs (danger/alarm/normal/standby status), and the programmable delay trigger time can be flexibly adjusted between 0.1-30 seconds. It can determine the ISO 10816 vibration level in real time and visualize the axis trajectory; intelligent diagnosis is highly integrated, supports Modbus RTU/TCP, PROFIBUS DP communication protocols, natively adapts to System 1™ diagnostic software, built-in up to 6400 lines of FFT spectrum analysis, and can also realize fault mode AI prediction with the help of BN Connect platform; industrial-grade reliability is outstanding, it can operate stably in a wide temperature range of -40℃~+85℃ (in compliance with EN 60721-3-7 Class 3M6 standard), and has anti-electromagnetic interference capability (EN 61326-1), SIL2 safety certification (IEC 61508), and ATEX Zone 2 explosion-proof certification is available for some models.
