Drifter Plus Tide Buoy
1. Key Features & Product Advantages
-
Surface-Seabed Cooperative Measurement: The buoy and TD work synchronously to form an observation link from the surface to the seabed, capturing wave info alongside changes in seabed water temperature, pressure, water level, and tidal level.
-
Flexible Anchoring Deployment: Custom-adapted mooring based on target sea depth, wave conditions, and task cycle to satisfy long-term fixed-position observation needs.
-
Positioning & Communication Services: Integrated positioning and communication modules regularly report buoy location, equipment status, and observation data directly to a cloud platform for online access, query, and download.
-
Modular Expansion Design: Configurable surface and seabed modules allow flexible selection of communication methods, power supply capacity, and cable length according to application requirements, simplifying deployment and maintenance.
-
High-Precision Sensor Performance: Equipped with wave sensors, sea surface air pressure sensors, and high-accuracy TD sensors ($\pm0.005^\circ\text{C}$ temperature accuracy, $\pm0.1\%\text{FS}$ pressure accuracy).
2. Production Process
-
Marine-Grade Hull Molding: Crafted with high-durability Polyethylene (PE) material engineered for water-tight integrity and long-term marine exposure.
-
Surface & Seabed Electronics Assembly: Precise integration of wave sensors, air pressure sensors, high-strength umbilical cable interfaces, and low-power processing boards.
-
Sensor Integration & Cable Testing: Assembly and testing of the seabed temperature-pressure (TD) module and communication cable.
-
IP68 Hermetic Sealing: Strict sealing, double-O-ring potting, and pressure testing to achieve IP68 protection grade.
3. Quality Inspection
-
Hydrostatic & Leak Testing: Verification of underwater seal integrity up to required depth ranges (20m–350m).
-
Environmental & Temperature Chamber Testing: Operates verified between $-5^\circ\text{C}\text{ to }+35^\circ\text{C}$ and storage tested from $-20^\circ\text{C}\text{ to }+60^\circ\text{C}$.
-
Telemetry & GPS Verification: Testing of Iridium satellite communication and cloud platform data sync.
-
30-Minute Transmission Burn-In: Pre-shipment functional burn-in test validating regular 30-minute default return frequencies and data logging to internal 32GB SD card storage.
