SeaView Systems SVS-603 Wave Sensor

Description

Features of the SVS-603 include:

• Very low power consumption; fits the smallest power budget
• Very small footprint; sold packaged or as bare PCB
• 3-D motion, rotation and compass heading in all dimensions to cover nine degrees of freedom
• Sophisticated onboard electronics provide near-real-time wave statistics
• On-board temperature compensation for highest accuracy
• On-board data logger capable of logging as much as ten years of wave data
• Easy configuration to match your exact sensing rate and output requirements
• Readily interfaced with transmitter using NMEA or other configurable data output
• Outputs “First-5” Fourier wave coefficients for NOAA compliant data logging/transmission

The SVS-603 can be used to replace existing sensors, to upgrade existing buoys, or to add
wave sensing capabilities to even the most compact buoys. Among the wave data that are available as outputs from the sensor are:

• Heading in degrees
• Significant wave height in meters (H_s)
• Wave period in seconds
• Wave direction in degrees from north
• Maximum wave height (H_max)
• Wave period at H_max
• Full wave spectrum (raw or processed)
• Custom outputs as required

Available SD Card Outputs

• Wave Statistics
• Displacement time series (603HR only)
• Directional spectrum
• Accelerations
• Raw sensor outputs including X, Y, Z accelerations; pitch;  roll;  heading; and angular velocities (603 only)

Accuracy Metrics

• Significant wave height  (H_s) <1%
• Period <1%
• Wave direction ±4 degrees (SVS-603)*;  ±2 degrees (SVS-603HR)*

Available Ports and Slots

• RS232
• Adjustable baud rate (2.4-115.2 kbps)
• Micro-USB
• Micro-SD card

Dimensions

• 53.5mm length
• 68mm width
• 23mm height

* Dependent on orbital buoy motion.

Available as a bare circuit board or in the SVS-603ME marinized enclosure, a precision CNC machined 6061 air-craft grade billet aluminum enclosure with an anodized finish. The enclosure has been pressure proven to 550psi. The IP67 bulkhead connector is available either on the top surface or the side, depending on space constraints and per the IP67 rating is water-tight under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion). A 2m IP67 connector cable is also included.
