【文章內(nèi)容簡(jiǎn)介】 ng the temperature sensor 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 sensors。 Making the pressure transmitter with the ceramics. The high polymer can bee the proportion adsorption and the release 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 diele ctric medium, determines the electric capacity cape city the change, then obtains the relative humidity. Making the plasma using this principle to gather the legitimate polystyrene film temperature sensor below, it has the characteristic. Measured the wet scope is wide。 The temperature range is wide, may reach 400 ℃ ~ +1,500 ℃ 。 The speed of response is quick, is smaller than 1S。 The size is small, may use in the small space measuring wet。 The temperature coefficient is small. The ceramic electric capacity type pressure transmitter is one kind does not have the intermediary fluid the dry type pressure transmitter. Uses the advanced ceramic technology, the heavy film electronic technology, its technical performance is stable, the year drifting quantity is sma ller than %, warm floats is smaller than 177。%/10K, anti overloads strongly, may reach the measuring range several hundred times. The survey scope may from 0 to E+H Corporation and the American Kahlo Corporation product is at the leading position. The optical fiber application is send the material significant breakthrough, its uses in most early the optical munication techniques. In the optical munication use discovered works as environmental condition change and so on the temperature, pressure, electric field, magic field, causes the fiber optic transmission light wave intensity, the phase, the frequency, change and so on the polarization condition, the survey light wave quantity change, may know causes these light wave physical quantity the and so on quantitative change temperature, pressure ,electric field, magic field size, uses these principles to be possible to develop the optical fiber sensor. The optical fiber sensor and the traditional sensor pare 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 sensor Japan is in the advanced level. Like Idec Izumi Corporation and Sun x Corporation. The optical fiber send receiver and the integrated path of rays technology unify, accelerates the optical fiber sensor technology development. Will integrate the path of ray’s ponent to replace the original optics part and the passive light ponent。 enable the optical fiber sensor to have the high band width, the low signal processing voltage, the reliability high, the cost will
