Precise depth determination is essential in marine navigation, construction and research work-offshore. Underwater ultrasonic sensors manufactured by Seaward Tech offer extensive and credible information on the depths offered even in a tricky underwater environment. These are the main aspects which guarantee the effectiveness of the measurements.
High-Frequency Signal Precision
Our sensors typically employ optimized ultrasonic frequencies (most commonly 200kHz-700kHz) which offer a tradeoff between resolution and range. Higher frequencies yield more precise measurement in shallow waters and specially-designed lower-frequency versions remain accurate in deeper usages as far down as 3,000 meters.
Advanced Signal Processing
The sensors include:
Time-of-flight computation programs
Wave- interference noise filtering
Compensation- temperature/salinity
Technology of multi-pulse averaging
Through this a depth hedge of ±0.1% is achieved despite the water column disturbances.
Robust Pressure-Resistant Design
Our sensors are built with titanium alloy housings that have pressure-compensated electronics and can be used at any depth with a stable calibration. The pressure cycling tests are carried out on each unit more than 150% of its rated depth.
Anti-Fouling Protection
To prevent off school growths that might distort measurements special transducer coatings are used and an optional wiper system. It is notably useful in the long-term mooring activities.
Multi-Beam Verification
Some models have dual-beam verification which compares measurements of primary and reference beams, and automatically identifies potential error due to suspended sediments or thermocline.
Integration Capabilities
The sensors are in support of:
Standard NMEA 0183/NMEA 2000 out.
Modbus interfaces/RS485 RS485/Modbus interfaces
Surface systems enabled real time data into the systems
The depth measurement sensors of Seaward Tech integrate these functions together with the capability to change parts and perform simple calibrations by the user. When it comes to navigation of ROVs, dredging or tidal monitoring, our solutions will provide reliability that professionals need in high-stakes application in the underwater environments.
