Development of Sensor New Technology
Sensor is one kind component which can transform the physical quantity, chemistry quantity and the biomass into electrical signal. The output signal has the different forms like the voltage, the electric current, the frequency, the pul and so on, which can satisfy the signal transmission, processing, recording, and demonstration and control demands. So it is the automatic detection system and in the automatic control industry .If automatic Technology is ud wider, then nsor is more important.
Although there are exception ,most nsor consist of a nsing element diaphragms,bellows,strain tubes and rings, ourdon tubes, and cantilevers are nsing elements which respond to changes in pressure or force and convert the physical quantities into a displacement. This displacement may then be ud to change an electrical parameter such as voltage, resistance, capacitance, or inductance. Such combination of mechanical and electrical lements form electromechanical transducing devices or nsor. Similar combination can be made for other energy input such as thermal. The Photo, the m万古长青
agnetic and the chemical,giving thermoelectric, photoelectric,electromaanetic, and electrochemical nsor respectively.
The relationship between the measured and the nsor output signal is usually obtained by calibration tests and is referred to as the nsor nsitivity increment measured increment. In practice, the nsor nsitivity is usually known, and, by measuring the output signal, the input quantity is determined from increment K1.
In information age, the information industry includes information gathering, transmission, process three parts, namely nsor technology, communication, computer technology. Becau of ultra large scale integrated circuit’s rapid development after having been developed Modern computer technology and communication, not only requests nsor precision reliability, speed of respon and gain information content request more and more high but also requests its cost to be inexpensive. The obvious traditional nsor is eliminated gradually becau of the function, the characteristic, the volume, the cost and so on. As world develop many countries are speeding up to the nsor new technology’s
rearch and the development, and all has obtained the enormous breakthrough. Now the nsor new technology development mainly has following veral aspects.

Using the physical phenomenon, the chemical reaction, the biological effect as the nsor principle therefore the rearches which discovered the new phenomenon and the new effect are the nsor technological improving ways .it is important studies to developed new nsor’s the foundation. Japane Sharp Corporation us the superconductivity technology to develop successfully the high temperature superconductivity magnetic nsor and get the nsor technology significant breakthrough. Its nsitivity is so high and only inferior in the superconductivity quantum interference component. Its manufacture craft is far simpler than the superconductivity quantum interference component. May u in magnetism image formation technology. So it has the widespread promoted value.

Using the immune body and the antigen meets one another compound when the electrode surface. It can cau the electrode potential change and u this phenomenon
电影家to be possible to generate the immunity nsor. The immunity nsor makes with this kind of immune body may to some organism in whether has this kind of ant original work inspection. Like may inspect somebody with the hepatitis virus immune body whether contracts the hepatitis, plays to is fast, the accurate role. The US UC sixth branch has developed this kind of nsor.

The nsor material is the important foundation for nsor technology, becau the materials science is progressive and the people may make each kind of new nsor For example making the temperature nsor with the high polymer thin film; The optical fiber can make the pressure, the current capacity, the temperature, the displacement and so on the many kinds of nsors; Making the pressure transmitter with the ceramics. The high polymer can become the proportion adsorption and the relea hydrogen along with the environment relative humidity size. The high polymer electricity lies between the constant to be small, the hydrogen can enhance the polymer the coefficient of dialectical loss. Making the capacitor the high polymer dielectric medium, determines the electric capacity cape city the change, then obtains the relative humidity. Making the plasma usin
g this principle to gather the legitimate polystyrene film temperature nsor below, it has the characteristic.化妆品销售
The ceramic electric capacity type pressure transmitter is one kind does not have the intermediary fluid the dry type pressure transmitter. Us the advanced ceramic technology, the heavy film electronic technology, its technical performance is stable, the year drifting quantity is smaller than 0.1%F.S, warm floats is smaller than ±0.15%/10K, anti- overloads strongly, may reach the measuring range veral hundred times. The survey scope may from 0 to 60mpa.German E+H Corporation and the American Kahlo Corporation product is at the leading position.

In the optical communication u discovered works as environmental condition change and so on the temperature, pres-sure, electric field, magnetic field, caus the fiber optic transmission light wave intensity, the pha, the frequency, change and so on the polarization condition, the survey light wave quantity
change, may know caus the light wave physical quantity the and so on quantitative change temperature, pressure ,electric field, magnetic field size, us the principles to be possible to develop the optical fiber nsor. The optical fiber nsor and the traditional nsor compare has many characteristics: Sensitivity high, the structure simple, the volume small, anti-corrosive, the electric insulation good, the path of rays may be curving, be advantageous for the realization telemeter and so on. Optical fiber nsor Japan is in the advanced level. Like Idec Izumi Corporation and Sun x Corporation. The optical fiber nd receiver and the integrated path of rays technology unify, accelerates the optical fiber nsor technology development. Will integrate the path of ray’s component to replace the original optics part and the passive light component; enable the optical fiber nsor to have the high band width, the low signal processing voltage, the reliability high, the cost will be low.
