Broadsens wireless ultrasonic thickness sensors are ideal for corrosion erosion monitoring, bolt preload and tension measurements and monitoring. The wireless ultrasonic sensors have wide measurement range with high accuracy. The wireless ultrasonic thickness sensors not only can measure the thickness change in real time, but also have data logger ability. In real time mode, users can measure thickness, bolt length (preload & tension) remotely through Broadsens's edge-computing gateways. The edge-computing gateways can store years of measurement data, and stream data to clouds optionally.
Key Features
The sensors have the following features:
- The only solution of instant response with 10 year or more battery life in the industry
- Large measurement ranges from 3mm up to 1,000mm
- High resolution of 0.001mm with 0.01mm repeatability at room temperature
- Replaceable ultrasonic probes
- Designed for harsh environments with IP67 waterproof rating
- Data logger ability that allows the sensors to work in completely sealed metal Faraday chamber
- Parallel monitoring with multiple WUT sensors
- Scales to millions of sensors and gateways with no upper limit
- Easy installation and usage
- Cost effective
Wireless ultrasonic thickness sensor WUT204-S
Applications
- Bolt preload & tension monitoring. WUT series sensors can be used for both dynamic bolt preload measurements, and long-term bolt preload monitoring, thanks to the best battery efficiency in the industry.
- Corrosion & erosion monitoring. WUT series sensors can be installed permanently for long-term real-time corrosion & erosion monitoring of pipelines, refineries and other important infrastructures.
