Self-contained hydrophoneIt mainly consists of sensors, data acquisition systems, communication systems, and power supply systems. Sensors are responsible for converting underwater sound into electrical signals; The data acquisition system amplifies, filters, and performs analog-to-digital conversion on electrical signals; The communication system sends the processed data to the ground station or remote server; The power system provides continuous power supply for the entire system.
Self-contained hydrophoneProduct Features:
Autonomous floating: It can float autonomously in water without the need to be fixed on the seabed or surface, with high flexibility and adaptability, and can work for a long time in unmanned marine environments.
High sensitivity: Domestic products can provide background noise levels as low as μ V, which can be directly used for measuring zero level sea state environmental noise in deep sea environments, comparable to the technical level of similar foreign products.
Anti electromagnetic interference: Based on fiber optic and optoelectronic technology design, it has strong anti electromagnetic interference ability.
Durable in harsh environments: The structure is lightweight and can adapt to harsh underwater environments.
Easy to telemetry and array: can form hydrophone arrays with various topological structures, such as vertical arrays, horizontal arrays, T-shaped arrays, etc., suitable for flexible array formation.
Strong endurance: Some products, such as the New Zealand ST600 self-contained hydrophone, can last up to 160 days.
High acquisition accuracy: Adopting high-precision differential amplification and multi-stage vibration reduction design, it has high signal-to-noise ratio and acquisition accuracy.
Low background noise: Domestic products can provide background noise levels as low as μ V, suitable for measuring zero level sea state environmental noise in deep sea.
Scalable array: can form hydrophone arrays with various topological structures, such as vertical arrays, horizontal arrays, T-shaped arrays, etc., to meet different monitoring needs.
Support user customization: Customized design can be carried out according to user needs to meet the requirements of specific application scenarios.
