Product Description

Geolux LX-80-15 10 Hz oceanographic radar sensor is a high sampling frequency version of the radar level sensor, which is targeted towards tidal monitoring, oceanographic, coastal and maritime applications. The level sensor uses radar technology to accurately measure the distance between the radar instrument and the surface of the water. The water level measurements are repeatedly performed up to 10 times per second. An internal wave analysis module uses these water level measurements for advanced wave analysis. Wave parameters, such as significant wave height, zero up-crossing period, crest period as well as minimum, maximum, mean and median water level are automatically calculated by the radar unit. The instrument can internally store up to 20 minutes of water level data to be used for calculation of the wave parameters. The low power consumption of the instrument, the integrated wave analysis module, small form factor and a rugged enclosure make this instrument easy to setup and use.
