Feature Rich Vibration Data Collection

Real-time vibration monitoring ability

With SVT200-V wireless vibration sensor, the BroadVibra software shows the vibration velocity, acceleration RMS and temperature measurement in real time. If any one of the parameters exceeds a user-defined threshold, then an alarm will be sound within 1 second typically. This real-time vibration monitoring ability is extremely useful to detect sudden events such as impacts or accidents or operator errors. Sudden events will not be detected, nor predicted with predictive maintenance method and can account for more than 20% of machine failures.

Advanced DAQ modes

BroadVibra vibration analysis software provides multiple modes of data acquisition: including real-time mode, batch mode and single DAQ mode. Sampling rate in real-time mode ranges from 50Hz to 200Hz; sampling rate in batch mode and single DAQ mode range from 400Hz up to 25.6kHz. Both real-time mode and batch mode provide unlimited data acquisition points. In single DAQ mode, sampling points range from 2,048 up to 16,384. All three modes support synchronization among sensors in the same group. Acceleration range is also adjustable.

Database history data review

Integrated time-series database supports long-term vibration data review and analysis. In default setup, up to 1-year history data can be reviewed and plotted any time with the software. The software supports latest data query or allows user to enter a data and time to review the data in a specific time period. The software allows flexible data points selection. Small data points allow fast history data query, and large data points allow user to check data in a long time span. Data curve can be zoomed in for detailed view and can be exported into CSV format for further analysis.

Advanced Vibration Analysis and Automation

FFT Analysis & Filtering

FFT analysis can be carried at each vibration sensor. In the figure, the top chart is the FFT waveform, and the bottom chart is the corresponding time-domain waveform. The waveforms can be zoomed in easily for detailed view. FFT result and time-domain data can be downloaded from the interface. High pass, low pass and band pass filters can be added for the time domain data and FFT analysis. BroadVibra provides the best filtering abilities in the vibration analysis, in which users can adjust the cutoff frequency freely without any limitation. Filtering order can be adjusted too.

vibration daq & analysis timer

Automatic DAQ and analysis

Timer can be set up for each zone/group for automatic DAQ. The default duration for each input is 5 minutes. For fast input, one can choose “select all” when one wants to take data every day. Since Broadsens ultra low power wireless sensors provides the highest battery efficiency in the industry, one can set up multiple data acquisition times for each group of sensors in a day. Analysis can be scheduled to start automatically too. This simplifies user's work and makes the analysis very consistent each day. The analysis result is saved into the database for easy review later on.

Alarm and email notification

It is easy to set up vibration alarms for SVT-A series sensors and SVT-V series sensors. For SVT-A series sensors, alarm thresholds can be set up for each zone/group differently. The thresholds include acceleration levels for x, y & z axes and temperature. For SVT-V series sensors, each sensor can have different threshold including vibration velocity, acceleration RMS and temperature. Alarm LED will turn into red color when the vibration exceeds a predefined level. Email notification can be enabled and disabled by togging a switch easily. The alarm can be sent to multiple recipients with detailed alarm information including alarm sensor id and measurements.

MQTT data upload to server

Data can be uploaded in real time to user’s private server or clouds by enabling the server data upload option. Each gateway has a unique name. There is no limit on how many gateways a factory uses, so that tens of thousands of gateways can be used. Switch the “MQTT data output” switch on to allow the MQTT raw data upload. To save bandwidth, the MQTT raw data output can be turned off. One can select only transmit the alarm and analysis result to the server/cloud instead. For help to set up the MQTT subscription on the server side, Broadsens will provide the MQTT protocol and data parsing examples.
