sensor

Sensor (English name: transducer/sensor) is one kind of detector set, can Piezo Buzzer feel the information which surveys, and can examine the information which feels, transforms into the electrical signal according to certain rule or other needs the form the information output, satisfies requests and so on information transmission, processing, memory, demonstration, record and control. It is realizes the automatic detection and the automatic control most important link. The people for from the outside gain information, must draw support the sense organ.
The sensor compiles the picture selection (6), but depends on the people own sense organ only, their function by far was insufficient in the research natural phenomenon and the rule as well as the production activity. In order to adapt this kind of situation, needs the sensor. Therefore may say that the sensor is the human five senses extension, also calls it the electricity five senses.
The new technological revolution’s arrival, the world starts to enter the information age. In using in the information process, must first solve is must gain the accurate reliable information, but the sensor is gains in the nature and the realm of Magnetic Transducer production the information main way and the method.
In the modern industry production automation production process, must use each kind of sensor in particular to monitor and in control production process each parameter, causes the equipment work in the normal state or the optimum condition, and enables the product to achieve the best quality. Therefore may say that did not have the numerous fine sensors, the modernized production also to lose the foundation.
In the basic subject research, the sensor has the prominent status. The modern science technology’s development, entered many new domains: For example must observe over a thousand light years macroscopically the boundless universes, microscopically must observe slightly to the fm granule world, on longitudinal must observe is hundreds of thousands of year heavenly body evolution, short to s instantaneous response. In addition, but also appeared to deepened the material to know that to develop the new energy, the new material and so on has the influential role each kind of violent engineering research, like superhigh temperature, ultralow temperature,Loudspeaker ultrahigh voltage, ultrahigh vacuum, megagauss field, ultra weak magnetic field and so on. Obviously, must gain the information which the massive human sense organ is unable to gain directly, has not adapted the sensor is impossible. Many basic science research’s barrier, first lies in the object information the gain existence difficulty, but some new mechanisms and the high sensitivity examination sensor’s appearance, will often cause in this domain the breakthrough. Some sensor’s development, often is some edge discipline development pioneer.
The sensor already seeps to such as the industrial production, the universe development, the sea survey, the environmental protection, the resources investigation, the medicine diagnosis, the bio-engineering, even the cultural relics preservation and so on pan-domain extremely. May not exaggerate said that from boundless outer space, to vast sea, down to each kind of Micro Speaker complex engineering system, each modernized project, cannot leave various sensors nearly.
Thus it can be seen, the sensor technology in the develop economy, the impetus social progress aspect influential role, is very obvious. Various countries very take this domain the development. The trust near future, the sensor technology will present a leap, will achieve with its important position symmetric new level.
