WAVES-1C Wave Sensor

WAVES-1CType Wave Sensor

1 Overview

WAVES-1C Wave SensorMeasure waves using the principle of gravitational acceleration. According to classical wave theory, the wave height, wave period, wave direction, wave energy density spectrum, and wave direction spectrum are calculated by measuring the motion posture and acceleration of the carrier. It has high measurement accuracy, low power consumption, small size, and light weightcostLow, stable and reliable.Specially suitableforDisposable abandonmentdriftformulaFloat usage. This type of wave sensor strictly follows the measurement standardsThe relevant provisions of GB/T14914 "Ocean Observation Specification" shall be implemented.

This type of wave sensor uses domestically produced motion sensorsSensors.
