Drift Buoys Improve Underwater Noise Monitoring

The winter issue of Environment, Coastal and Offshore Magazine (ECO) highlights an article about our data loggers and drift buoys and how they were utilised to measure underwater noise on tidal turbines. This study aimed to identify the possible impact of such noise on marine life near the coast of Shetland. Don’t miss the opportunity […]

Measuring the vibrations of the ocean

Environmental Impact of High Amplitude Acoustic Signals on Fish and Invertebrates Why? The offshore renewable market is growing rapidly. High amplitude acoustic signals have been identified as a threat to marine life. Fish and invertebrates detect the particle motion of an acoustic field rather than the SPL. Particle motion must be measured indirectly to cover […]

Scalare – Capacitive Transducer Power Amplifier

Introducing Scalare: Our New Capacitive Transducer Power Amplifier – designed to drive capacitive sonar transducers and similar capacitive loads. Capacitive transducers are notoriously difficult loads to drive for off-the-shelf amplifiers. These amplifiers are usually designed for the PA market and are for driving resistive loads. To overcome the difficulties of driving capacitive loads, impedance matching circuits […]
