The abidance of national economy develops to rise with what the city changes a standard quickly, to food industry of China development created giant demand vacuum, food consumes gross to will increase ceaselessly, commodity sex consumption is replaced increasingly self-sufficient model consumption, industrialized food proportion grows stage by stage, provided vast market space for food industry development. In food industry, rate of technological process automation is higher and higher, for instance automation technology already occupied 50% above in the product line that pack, used computer design and Electromechanical unifinication control in great quantities, the purpose is to improve productivity, those who improve facility is flexible with flexibility. Sensor regards automation as crucial core of the system, also had applied in food industry in great quantities.

Does FISO microwave assist chemistry and: of summary of microwave food solution? Housing bully banter says meal ひ pilfer warmths ablaze ⑹ of ⅰ of  of room of  of captive of target of Mou orangutan Jie calls vanadium  ah ⑽ ⒉ ㄊ calls food of W of  of ⅰ of fragrant commonplace ぁ oven of test, MW apply related research of design and test, new material, MW and RF etc, and the counterpoise in considering to develop a process wants parameter- – the measurement of temperature and pressure is a difficult problem all the time, provide investigation to understand home to show level uses thermocouple mostly or infra-red measure Wen Yi to measure temperature, because thermocouple suffers the interference such as electromagnetism, microwave, radio frequency easily, the actual measurement when cannot coming true so is measured, collection temperature data usability is not tall, and infra-red although,measure can when actual measurement quantity, but its dispute contact is measured suffer a lot of elements to disturb (especially water vapour) , and measure precision to also do not satisfy research to ask, so two kinds of methods cannot very good settlement temperature measures an issue, to research the job brings a lot of inconvenience. The smooth fiber sensor of Canadian FISO company solved temperature and pressure to measure an issue well, FISO sensor fights the interference such as electromagnetism, microwave, radio frequency completely, inside the food in the microwave of the fact when much passageway is online that monitor, outside each place temperature difference and change, to research food the composition below different temperature and content provide reliable and accurate data, it is OK to be controlled by software through RS232 and computer connection at the same time curve of very intuitionistic observation temperature, pressure changes. Of fiber-optic test system form: The fiber-optic test system of Canadian FISO company is main by demodulator of probe, fiber-optic extension line, signal, accessory 4 parts are formed. Principle: 1.F-P principle: ? ? of hold a memorial ceremony for of ú of plum of take along sth to sb compares Luo Te (Fabry–Perot) antrum is the parts of an apparatus of inductive physics parameter, have a test to the physical parameter such as temperature, pressure, meet an emergency, displacement, through fiber-optic transmit relevant test signal go out, be linked together with signal demodulator the “SC” join head that uses industrial standard.

Fiber-optic temperature sensor – FOT-L-BA/SD

 

FISO fiber-optic sensor uses interference principle, fit the environment that misfires in food industry environment and dielectric sensor very much. FISO sensor and its corresponding signal recuperation implement can comprise complete fiber-optic pass feeling system. Interference measures sensor (FPI) is comprised by the mirror with opposite two sides commonly, the space that breaks up two sides mirror calls cavity (or empty) length. Reflexing the light in FPI is classics wavelengh modulation, as identical as cavity length. By what design accurately FPI general meet an emergency, temperature, displacement or pressure change become the function of cavity length. Is the principle of FISO sensor: ?

The position of reflection happening is different, corresponding optical path difference also differs. When the transverse shift of agree form medium shows displacement changes, this displacement changes will by FP antrum ascertain and translate into. Because FISO sensor fights the interference such as electromagnetism, microwave and radio frequency completely, much passageway is online real time detects the difference of each temperature inside the food in microwave and change, to research food the moisture below different temperature and content provided reliable and accurate data. Here advocate the fiber-optic temperature sensor that pushs labour to collect a net to be imported from Canada – FOT-L-BA/SD, this is one suits to measure the fiber-optic temperature sensor of temperature below extreme environment very much, environment of this kind of extreme includes the RF of environment of microtherm, nucleus, microwave and high strenth to wait. FOT-L collect is all you expect from ideal sensor implement the good character that gets personally at an organic whole. Accordingly, although be below extreme temperature and adverse environment, this kind of sensor still can offer high accuracy and reliable temperature to measure.
