Tsunamis, the most dramatic and destructive of waves, often pass unnoticed at sea because of their small amplitude (wave height) offshore, and very long wavelength (often hundreds of kilometres).
Tsunami warning systems use information from seismic and sea-level monitoring instruments to detect, locate and determine possible tsunamis. The reliability of the system depends on the accuracy and sensitivity of the sensor.
PRESENS' high-accuracy pressure and temperature transmitter, the PRECISE, provides the ultimate precision in water level measurements. With an accuracy better than ±0.01%FS, low drift and high resolution, the PRECISE sensor offers a unique level of performance in combination with robust construction.
