Easy to connect and install

Designed for fast and easy R&D and industrial Structure Health Monitoring 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 length.

Why choose BHU series 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 typical piezoelectric transducer is thin, rigid and very fragile, which makes it require extra care to install. The piezoelectric sensors are also vulnerable to external impacts, shocks, and strains. Broadsens BHU series piezoelectric sensors solve the problem by adding extra protection layer on top and size of the piezo disc.
