The long wait is over! Industrial first Wireless Optical Speed sensor (tachometer) WOS200 is formally released in March 2025. WOS200 is a completely wireless  rotation speed sensor powered by battery that allows for remote monitoring with multiple years of battery life. No more messy cables and installation is so much easier than before! The sensor battery can be replaced at the end of life in the field easily by a technician. Compared to hall-effect tachometers, optical speed sensor allows for much longer distance between the machines and the sensor. Due to high power consumption of optical LED, there are many technical challenges to overcome to design a true wireless optical rotation speed sensor. After spending lots of engineering efforts, Broadsens made it happen.  The world's first true wireless tachometer for online monitoring is ready to ship now!

Wireless speed sensor (tachometer) WOS200 is a great add-on sensor to Broadsens's comprehensive machine condition monitoring product line that includes wireless vibration & temperature sensors, wireless high temperature sensors, wireless ultrasonic thickness sensors and wireless IMU. WOS200 further improves the leadership of Broadsens in the field of predictive maintenance and wireless low-power sensors.

All Broadsens wireless sensors can be used with the edge-computing gateways for long-lasting remote monitoring. Monitoring software is preinstalled in the gateways with life-time license, no subscription required.

As one of the largest wireless vibration & temperature sensor system providers in the industry, Broadsens's low-power wireless sensor systems are preferred by many large companies, and deployed more than 50 countries worldwide by the end of 2024.

In 2024, Broadsens released SVT-L series long-range wireless vibration & temperature sensors that can reach 1km distance in open space. Broadsens also improved its industrial best selling wireless vibration and temperature sensors: SVT-V series sensors. The SVT-V series sensors are the only effective condition monitoring solutions of machines with random up and down times, since the sensors monitor the machines continuously in real time. Auto acceleration range adjustment feature is added to the sensors for better resolution in both small acceleration applications (such as Structure Health Monitoring) and large acceleration applications (such as heavy machines). OTA firmware upgrade ability is added to the SVT-V series sensors without sacrificing the power consumption.

Broadsens released industrial leading wireless ultrasonic thickness gauge WUT204-S with the most advanced features. The sensor can be used for both bolt preload monitoring and corrosion monitoring. The corrosion monitoring feature will be further improved with the upcoming WUT201 sensor and BUP4SH probe for wide temperature range applications in 2025.

Wireless Optical Speed sensor WOS200 is to be released in the first quarter of 2025. WOS200 is an advanced wireless optical rotation speed sensor that monitors the machine rotation speed, which is important for machine condition monitoring. WOS200 can be used with Broadsens's wireless vibration & temperature sensors for comprehensive monitoring and predictive maintenance. WOS200 is completely wireless, and its battery can be replaced easily by users. The distance from WOS200 lens to the machine shaft can be up to 50 cm (20 inches) compared to mm distance from other optical rotation speed sensors or hall effect speed sensors.

Broadsens is also on-pace to receive IECEx and ATEX certificates for its SVT-L series wireless long-range vibration & temperature sensors, and SVT series standard wireless vibration & temperature sensors.

Broadsens will also release server-side software for customers who need platform solutions in Q1 2025. The server-side vibration monitoring software can be installed on Windows or Linux machines to monitor large amount multiple gateways. The server software can run on a local computer, or a cloud server. The communication between the server and gateways is through MQTT protocol.

Broadsens is committed to provide the best wireless vibration & temperature sensor system for industrial customers. With the largest selection of wireless accelerometers and temperature sensors, Broadsens provides 10-year long-term support for its products. Broadsens's machine condition monitoring software is provided with the edge-computing gateways with no subscription fee. The gateways are open to users for customization with endless possibilities. Please contact Broadsens for more details and sales.

As an industrial leader of wireless vibration and temperature sensors, Broadsens releases SVT-L series vibration sensors that can reach up to 1km range in open space (line of sight). The SVT-L series sensors integrate wireless accelerometer and temperature IC. SVT-L series sensors have the longest range among high performance wireless vibration sensors (based on BLE or Zigbee technology)  in the industry. Different from LoRa sensors (which is for very low data rate and very long distance), the SVT-L series sensors can transfer much larger amount of raw acceleration (vibration) data with comparable low power consumption.

The long-range wireless vibration sensors includes SVT-LA sub series and SVT-LV series. SVT-LA sub series include SVT200-LA, SVT300-LA and SVT400-LA, which operates exactly the same as the SVT-A series sensors, but triples the transmission range. SVT-LV sub series include SVT200-LV, SVT300-LV and SVT400-LV. They also operate exactly the same as the SVT-V series sensors with longer distance. Users can add, delete or change the sensor description like the standard SVT-A and SVT-V series sensors.

The SVT-L series sensors use ER18505 battery for higher power consumption than standard Broadsens sensors. The long-range wireless vibration sensor has an integrated power amplifier to boost both the transmission and receive signal. The transmission signal strength is up to 20dBi, which meets the FCC/IC and CE regulations.

The SVT-L series sensors are ideal for applications that require longer distance, or in locations where there is strong interference from structures. Users can use the longer range sensors to replace the standard sensors for these applications. The SVT-L series sensors work with Broadsens's edge-computing gateways exactly the same as the standard range sensors.

The weight of the SVT-L series sensors is 117 g (4.1 oz) including battery. The size of the sensor is 37x71 mm (1.46x2.80 inch) diameter x height.

The high sensitivity long range sensors SVT200-LA and SVT200-LV are ideal for structural health monitoring, and are being used for bridge, buildings, lighting poles, wind turbines and offshore platforms monitoring.

SVT-L series long range wireless vibration sensors are available to order starting from March, 2024. Please contact Broadsens for details.

Broadsens just released the industrial wireless IMU (Inertial measurement unit) SAG200. SAG200 integrates wireless accelerometer, gyroscope and magnetometer that offers 9 Degrees of Freedom (DOF). SAG200 utilizes Broadsens's proprietary low-power consumption technology, and achieves industrial-leading power consumption of less than 5mA when the IMU is taking measurements of 3-axis acceleration, 3-axis angular rate, 3-axis orientation, computing pitch, yaw and roll angle, transmitting the results to Broadsens's edge-computing gateway. The gateway supports Broadsens's best-selling wireless vibration and temperature sensors at the same time.

Wireless IMU SAG200 integrates ER18505 battery that can last up to 10 years if the sensor take measurements for up to 10 minutes a day (battery capacity will be reduced in hot or cold environments). The wireless IMU has the following main features:

• Ultra-low power consumption
• rugged design for industrial applications
• Leading battery life
• Multiple IMU parallel measurements
• Multiple group sequential measurements with timer
• History data review
• CSV file export
• Remote transmission via internet, WiFi or cellular network (edge-computing gateways  required)

Applications of wireless IMU SAG200 includes heavy machines, mining, bridges, bolt loosening, IOT etc.

In September 2023, Broadsens is happy to announce the release of next generation wireless edge-computing gateway GU300S, which supports global 4G LTE cellular network. GU300S can send data received from wireless vibration and temperature sensors remotely through cellular network to clouds, servers or a local PC. This is useful when there is no access to the local Ethernet or WiFi network. GU300S can also be controlled remotely via cellular network either through VPN or MQTT protocol. Before the release of GU300S, when local network is not available, user needs to use a dedicated 4G LTE router to connect to the gateways. GU300S saves the additional hardware investment and integrates the cellular network ability into one hardware.
