Hydrophone – Underwater Acoustics

The July fourth holiday is right around the corner. Here at Eastern Strategic Materials, we hope that everyone takes some well earned rest to relax and spend some quality time with their friends and family this weekend – perhaps even attend the local parades in your hometown. We’ll be attending the annual fireworks display here in NYC and we are hopeful that this year’s event will be an inspiring show.

As the month of July is bound to be hot and humid, our mind has wandered toward the respite provided by the beach and water. We thought it apropos to feature a hydrophone offering this month. We are spotlighting the H505L, a general purpose, self-amplified hydrophone sensor.

This model hydrophone is rugged, small, utilitarian, as well as being self-amplified  and suitable for a wide range of applications to capture underwater acoustic measurements. Favorable cost, durability, and an ultra low-noise internal amplifier are the benefits of this model. The amplifier eliminates common and problematic triboelectric cable noise, connector contamination problems and the requirement for an expensive in-line amplifier.

The unit and its cable are completely encapsulated in polyurethane. This limits/prevents water intrusion caused by cathodic action. The assembly uses preaged piezoelectric (PZT) sensing elements.

Some of the many applications include:
– Underwater biological studies:
– Ship noise studies:
– Pump and machinery studies:
– Monitoring of underwater ordinance:
