Easy to install and use
Designed for fast and easy R&D and industrial Structure Health Monitoring (SHM) applications, the BHU series of ultrasonic transducers are the patent-pending mechanically strengthened piezoelectric sensors. The ultrasonic transducers are extremely easy to install, resistant to external impacts and harsh environments in operation. Each transducer features a specially designed metal enclosure and high-quality shielded cable, making it robust and reliable. BHU series ultrasonic transducers are permanently bounded to a structure for easy online monitoring of the structural integrity.
The BHU series ultrasonic transducers can be used with Broadsens BroadScan series data acquisition device for fast SHM research, development and applications. A SHM system can be set up and running in a few minutes. The transducers are available in various cable length.

Why choose BHU series ultrasonic transducers
A piezoelectric transducer can be used to measure pressure, force, acceleration, or strain by converting mechanical stress to electrical charge. In Structural Health Monitoring (SHM) applications, the piezoelectric sensors can be used to generate and receive ultrasonic waveform such as lamb waves to detect structural damages. A piezoelectric transducer disc is thin and very fragile, which requires extra care to install and easy to break. The piezoelectric disc sensors are also vulnerable to impacts, shocks, and strains. Broadsens BHU series piezoelectric sensors are protected with metallic cases and extension wires, ultra compact, which are ideal for Structural Health Monitoring (SHM) applications such as crack monitoring and damage detection.
