The 21st Century is the century of the ocean. Owing to its rich biological, mineral, water area and water storage capacity, the ocean has become an important fulcrum of economic development, it is an important way to solve the problem of population expansion, shortage of resources and environmental deterioration. Nowadays, the development of marine blue land, expand the survival and development of space, has risen to national strategy of coastal countries in the world. The marine engineering and equipment is basic of marine development, control and comprehensive management, which embodies the national ocean competitiveness, while the level of marine engineering equipment technology to a certain extent, marks the national comprehensive national strength and technology level.
Along with the development of ocean observing system, the United States, Japan, Canada and Germany have developed deep sea absolute depth profiling instrument and deep sea high precision current meter, multi-electrode salt in deep sea environment and long-term continuous observation of ecological environment. Speed sensors, turbulence shear sensors, multi-parameter water quality measuring instrument, and has formed a series of products.At the same time, along with the development of ocean observing platform technology, various types of environmental monitoring sensors with automatic compensation of movement platform have made great progress. At present, We use the principle of piezoelectric ceramic sensor developed for the autonomous submersible, remote control submersible, underwater platform motion sensor.Platform temperature salinity, turbulence, pH, nutrients, dissolved oxygen and other sensors.
