Broadsens's wireless gateway software BroadVibra got new improvements. The software new version is 2.7.0, which offers the following new features:

1. Multiple group support for real-time wireless vibration and temperature sensors SVT200-V, SVT300-V and SVT400-V. Before version 2.7.0, each gateway only supports a single group of SVT-V series sensors. The multiple group ability allows at least 30 SVT-V series sensors connect to the gateway and send out overall vibration measurements in real time.
2. New miniature wireless temperature sensor SVT200-T support. SVT200-T is one of the best wireless temperatures sensors for industrial applications with wide temperature range, the shortest measurement interval with one of the longest battery life. The new software allows each gateway to support up to 100 SVT200-T sensors
3. Optimizing memory usage for live vibration data display, and the ability to hide a sensor type's information table.

There are 256 groups available for SVT-V series sensors. The number of groups can be extended to 65535 for very large-scale applications. Each group's real-time wireless vibration data can be observed in real time. Multiple sensors belong to the same group. So user can mount several SVT-V series sensors in the same group to monitor a large machine's condition.

The sensor data are saved in the time-series database inside the gateway. Each group's data can be reviewed together. User can also select individual sensor's data to review. With the "step forward" and "step backward" button, user can see the machine's condition in any time. The true real-time vibration monitoring ability of SVT200-V, SVT300-V and SVT400-V make them ideal for machine condition monitoring and predictive analysis.

User can also mount sensors in the same group to different machines.

The new software can be obtained through Broadsens's tech support. BroadVibra software can be updated with easy 1-click upload.

Wireless high temperature sensor SVT200-T is coming soon! This high performance miniaturized wireless temperature sensor SVT200-T is an upgrade to the ultra-low power wireless temperature sensor SVT100-T. Similar to SVT100-T, SVT200-T also measures contact surface temperature. But wireless temperature sensor SVT200-T offers a much wider temperature range than SVT100-T. Both sensors are designed for industrial usage and can survive harsh environments with IP68 water proof rating.

With the new design, SVT200-T can work in high temperature up to 105 degree Celsius (221 degree Fahrenheit), and as low as -50 degree Celsius (-58 degree Fahrenheit).

The following is a comparison of SVT200-T with SVT100-T.

Wireless high temperature sensor SVT200-T comes with food-grade safe metal base, which makes the sensor reusable. SVT200-T sends out temperature measurement every 15 seconds, which makes it one of the fastest wireless temperature sensors in the industry.

This miniaturized wireless high temperature sensor is also very low profile, which allows the sensor to be mounted in very tight spaces.

With all the added benefits, this miniaturized wireless high temperature sensor is also 20% cheaper than SVT100-T. So we are discontinuing SVT100-T and please use the latest high-performance, wide wireless temperature sensor SVT200-T in the future.

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.

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.
