Real-time wireless vibration monitoring of Pipe

Broadsens just increased its lead as one of the best wireless vibration sensor manufacturers in the industry. Broadsens upgraded its high performance real-time wireless vibration and temperature sensor SVT200-V again. The response time is increased from 1s to be less than 0.5 second. This makes SVT200-V response at least 100 times faster than other real-time wireless vibration sensors in the market. In the previous version, it is also possible for SVT200-V to miss some impacts if the impact event falls out of the monitoring window. In this new design, SVT200-V monitors the vibration event continuously without any gap. The power consumption is still comparable to the previous version, and it is the best in the industry.

In this application, SVT200-V is used for pipe monitoring. Broadsens's ultra-low power wireless vibration sensor SVT200-V is designed for real-time vibration and temperature monitoring.  SVT200-V has similar or even longer battery life than similar wireless vibration sensors and it has much smaller size. This is all thanks to Broadsens's innovative design and constant R&D investment.


Pump is in idle state. Small vibration level

Pump starts running. Vibration sensor #1 shows the sudden increase of vibration levels

SVT200-V is easy to mount with screws, ties, hanging wires or epoxy. In the following application, hanging wire is used to mount one sensor (sensor #1) on the pipe close to the hot water pump. We used two real-time wireless vibration monitoring sensors SVT200-V in this setup.

Another sensor #11 is mounted in another spot with lower temperature. The pictures show a clear comparison before the pump is on and after the pump is on. There is a sudden jump of vibration velocity and acceleration RMS value from sensor #1 when the pump is turned on.

When there is no vibration, SVT200-V sends out measurements every 10s. When there is vibration detected, the wireless vibration sensor switches to high frequency data acquisition mode and sends out measurements within 0.5s continuously.

Innovative design makes SVT200-V can detect both low frequency defects and high frequency defects with the machines.

SVT300-A and SVT400-A Ready, New Vibration DAQ Mode

New ultra-low power wireless vibration sensors SVT300-A and SVT400-A are available to pre-order now! Please be aware of that SVT400-A has more than 2-month shipping lead time since they are all pre-booked after the news announcement. We will do our best to make SVT400-A available ASAP. The major difference between wireless vibration sensors SVT200-A, SVT300-A and SVT400-A is the acceleration range. Here is the summary:

Wireless vibration sensorAcceleration range
SVT200-A+/-2g, +/-4g, +/-8g
SVT300-A+/-2g, +/-4g, +/-8g, +/-16g
SVT400-A+/-8g, +/-16g, +/-32g, +/-64g

Wireless Vibration sensors SVT200-A, SVT300-A and SVT400-A

SVT200-A has the best vibration sensitivity, SVT300-A covers the most commonly used acceleration range with the same noise performance as the SVT200-A, and SVT400-A covers the high acceleration applications such as online train pantograph monitoring or train bogie vibration monitoring. SVT400-A also has excellent signal to noise ratio compared to other wireless vibration sensors in the industry. Combined with Broadsens wireless gateway and vibration analysis software, Broadsens provides one of the best wireless vibration monitoring solutions in the industry. Broadsens's A-series wireless vibration sensors (SVT200-A, SVT300-A and SVT400-A) have the most advanced wireless data acquisition and transmission technology in the industry.

New Multi DAQ mode

An exciting new vibration data acquisition mode is available for Broadsens ultra-low power wireless vibration sensors. The new mode is called multi DAQ mode. The multi DAQ mode is basically automatic repeated run of single DAQ modes. The multi DAQ mode allows continuous data acquisition at user specified sampling rate and sample points. The sampling rate is guaranteed at the sensor side, which makes this mode extremely useful for vibration frequency domain analysis. Compared to single DAQ mode, the multi DAQ mode can take data continuously non-stop. All wireless gateways with vibration analysis software BroadVibra version 2.1.6 and later will have this mode. Previous version of wireless vibration sensors should also upgrade the firmware to have the capability.

Impact of global chip shortage on products shipment

Due to the pandemic that caused global chip shortage, Broadsens was also affected. Fortunately, Broadsens has allocated resources to stock up the supplies. Therefore, the delivery of multichannel ultrasonic thickness gauge UT200s, multichannel ultrasonic scanner BroadScan D200 and multichannel ultrasonic scanner BroadScan D110C will not be affected in the upcoming 2-3 months.

We especially allocated lots of resources for the popular ultra-low power wireless vibration sensors SVT200-A and SVT200-V,  so that there should not be a problem for the upcoming orders too. Although we were hit hard on the materials costs and labor costs, Broadsens will do the best to keep the same price while delivering the products on time. As an example, our wireless gateway costs increased at least 30% compared to half a year ago. But we expect that the cost will go down when global chip supply stabilizes in 2022. So we decided to keep the same price as before.

In the mean time, the upcoming wireless vibration sensors SVT300-A and SVT400-A were postponed slightly to meet the strong demands for wireless vibration and temperature sensors SVT200-A and SVT200-V first. All Broadsens wireless vibration sensors share the same high precision temperature sensors, which has +/-0.3 degree Celsius accuracy without calibration . The good news is that SVT300-A and SVT400-A will be available for pre-order in 1-2 weeks.

SVT300-A and SVT400-A are coming

Ultra-low power wireless vibration sensors SVT300-A and SVT400-A will be coming to Broadsens's machine condition monitoring and predictive maintenance system soon. Broadsens aims to provide the best wireless vibration sensors in the industry. SVT300-A offers the following acceleration measurement ranges: +/-2g, +/-4g, +/-8g and +/-16g; SVT400-A offers the following acceleration measurement ranges: +/-8g, +/-16g, +/-32g and +/-64g. The acceleration ranges are adjustable via the BroadVibra software. These two upcoming ultra-low power wireless vibration sensors will provide complete vibration monitoring solutions combined with SVT200-A and SVT200-V wireless vibration sensors. SVT200-A offers the best sensitivity range among the three models, SVT300-A covers the mostly commonly used acceleration ranges, and SVT400-A is ideal for high vibration environments with acceleration exceeding 16g constantly.


Similar to SVT200-A, SVT300-A and SVT400-A wireless vibration sensors provide the best battery efficiency in the industry. The typical idle current is 2.1uA. In real-time mode, the average current consumption is less than 200uA including data acquisition and transmission. Both upcoming sensors have the same footage as SVT200-A. They also have two base material options: hardened aluminum alloy 6061 for light-weight applications, and stainless steel for highly corrosive environments. For typical applications, it is recommended to use the hardened aluminum alloy 6061 due to its light weight property, which has less intrusion for vibration monitoring. Please note that even the stainless steel version of Broadsens' wireless vibration sensors are much lighter than most other wireless vibration sensors. A bulky vibration sensor will affect the vibration measurement accuracy.

SVT300-A and SVT400-A also have adjustable sampling rate from 50Hz up to 25.6kHz in different sampling modes. Therefore, the operation of SVT300-A and SVT400-A are exactly the same as the ultra-low power wireless vibration sensor SVT200-A. Broadsens A-series wireless vibration sensors are ideal for machine condition monitoring and predictive maintenance purpose. These sensors should be used with Broadsens's edge computing wireless gateway for advanced vibration analysis.

Firmware upgrade for Wireless Vibration Sensor SVT100-A

Broadsens recently released firmware upgrade for the popular wireless vibration sensor SVT100-A. The ultra-low power wireless vibration sensor SVT100-A was released in Fall 2020. SVT100-A was based on Broadsens's wireless sensors developed in 2016. The first generation wireless sensors include wireless temperature sensors, wireless sound sensors, wireless vibration sensor, wireless motion sensor, etc. However, the power consumption was very high at the time due to the WIFI protocol. It took Broadsens five years to get the power to the best in the industry. Although Broadsens released wireless vibration sensor SVT200-A as an upgrade in August 2021, we continue providing supports for previous sensors. This new firmware release brings the power consumption of SVT100-A to almost the same level as the SVT200-A. The latest firmware version for SVT100-A is 2.1. Customers who are using SVT100-A are strongly encouraged to upgrade their firmware to the latest version to enjoy the industrial leading wireless vibration sensor features. The new upgrade also allows SVT100-A to have adjustable sample points in single DAQ mode. The adjustable sample points range from 2,048 to 16,384 based on user's selection at the BroadVibra software control interface. (The previous version of firmware for SVT100-A only allows fixed 8,192 points).
