System Functions
Data Acquisition
The BH9000 system continuously and synchronously collects, analyzes, and stores various input signals. It automatically identifies the operating status of the equipment, such as startup/shutdown, speed ramp-up/down, and normal or abnormal conditions, and adjusts data collection based on the equipment's status.
Data Analysis
The BH9000 features advanced vibration analysis capabilities, including Waveform, Amplitude, Spectrum, Phase, Envelope Demodulation, Shaft Orbit, Shaft Position, Waterfall, Bode, Polar, Cascade, and P-V plots.
Protection Function
When there is an abnormality in the machine, the system drives relays output according to the logical operation which is set inside system to shutdown machine to avoid greater losses.
Current Output
Each input channel corresponds to a 4-20 mA output, which converts the sensor measurement value into a current signal for PLC, DCS or others.
Event List
Records alarm events and system events. The list of events allows you to recognize the status of the BH9000 at the moment of the event.
System Showcase
The BH9000 has been applied in hundreds of sets.
