Broadsens recently released its latest vibration monitoring and analysis software BroadVibra 2.6.6. The major improvement of this software is the advanced capability of industrial IOT (IIOT) applications. Users can remotely trigger the powerful FFT analysis and advanced filtering ability for vibration monitoring with MQTT protocol. The remote FFT analysis allows users to change sampling rate from 50Hz up to 25.6kHz, and from 2,048 sample points to 16,384 sample points. The advanced filtering includes high-pass, low-pass and band-pass filter with arbitrary cutoff frequencies. This makes Broadsens's wireless vibration monitoring system one of the most powerful for IIOT. Moreover, the MQTT message is in JSON string format, which makes it easy to parse at the MQTT broker. This feature improvement makes Broadsens's wireless vibration and temperature sensor system one of the best for industrial IOT applications.
Broadsens wireless vibration and temperature sensor system for IIOT applications
The system is very flexible that allows users to obtain key vibration monitoring parameters at different frequency range, including velocity and acceleration.
For example, to get the parameter Velocity (mm/s) RMS from 2Hz-1kHz range, you can do the following:
1. At the gateway MQTT configuration page, enable remote control and set the control password.
2. Send remote "DAQ command" to the wireless vibration and temperature sensors with sampling rate set at 3.2kHz or 6.4kHz, select single DAQ mode, 4,096 sample points (or 8,192 or 16,384 for better line of resolution)
3. Send remote "check DAQ status" command. Wait for the DAQ to finish. Or wait a fixed time
4. Send remote "FFT analysis" command, select "velocity" measurement, use bandpass filter cutoff frequency at 2Hz, 2nd cutoff frequency at 1kHz,
then voila, you get Velocity (mm/s) RMS from 2Hz-1kHz, triaxial velocity raw data and FFT analysis. You even get temperature with the measurement.
The MQTT message is in JSON string format, which can be converted to JSON objects easily. An example of the MQTT message is shown in Figure 2.
The cutoff frequencies can be adjusted continuously to obtain any desired envelope analysis with BroadVibra vibration analysis software's advanced filtering ability.

BroadVibra vibration monitoring & analysis software is pre-installed at Broadsens's wireless gateway. Users can access the software through any web browsers for sensor configuration and system maintenance.
To make the IIOT better, Broadsens's SVT-A series wireless vibration and temperature sensors can be trigger remotely via MQTT protocol too. With the latest software, users can select DAQ mode, DAQ sample rate, sensor group, sample points with the MQTT protocol. The new MQTT feature just make the best wireless vibration and temperature sensors in the industry even better.
