Abstract
The utility model provides a combined sound pressure and hydraulic pressure sensor, which aims at providing the combined sensor with small size, deep water resistance, high sensitivity and resistance to complex sea conditions as required by sea monitoring buoys. The sensor mainly comprises a cable head, a sound pressure hydrophone, a pressure sensor, a diversion block, an inner casing, a water density layer and a stretching resistance multi-core thin cable. The maximal diameter of the whole combined sensor is 26mm, and the height of the sensor is 115mm. The combined sensor has the advantages that pressure signals and sound pressure signals can be simultaneously obtained; the maximal stretching resistance is 200kg, and the water depth resistance is 3000m; and the size is small, and the combined sensor can be applied to different types of buoys.
