WAVES-1B Wave Sensor

WAVES-1BType Wave Sensor

1Overview

WAVES-1B 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, light weight, stability and reliability. This type of wave sensor strictly follows the measurement standardsGB/T14914The relevant provisions of the Ocean Observation Standards shall be implemented.

This type of wave sensor uses domestically produced motion sensorsSensors.
