Voltaic sensor applies mediumly in transducer

And the frequency control technology that the development at the beginning of 80 time rises, complied with industry to produce the demand that automation expands just about, initiated a period of brand-new intelligent electric machinery, the dated pattern that changes common electromotor to be able to move in order to decide fast way only, make electromotor reachs his to pull the condition that changes load to be in any beardless altering to fall to be able to ask to adjust rotate speed to output according to manufacturing technology namely, reduce electric machinery power comsumption to achieve a system thereby efficient the purpose that move. 80 time end, this technology introduces our country and get popularizing. Already was now in the electric machinery transmission of a variety of industries such as electric power, metallurgy, oil, chemical industry, papermaking, food, spin get applied actually. Current, frequency control technology has made way of a of technology of drive of contemporary electric power main development. Fan, pump kind wait for equipment to use frequency control technology implementation is energy-saving moving is our country an energy-saving key popularizes a technology, be taken seriously generally of national government, " People's Republic of China is managing energy law " label it the 39th times current technology tries to popularize. Carry out a proof, transducer is used at fan, pump kind circumstance of equipment drive control obtained remarkable section report result, the timing that is a kind of ideal controls fashion. Improved equipment efficiency already, satisfied manufacturing technology requirement again, and because of this reduced equipment to safeguard greatly, upkeep costs, still reduced stop production cycle. Mix directly indirect economic benefits is very obvious, one-time investment can be in equipment normally call in entirely in the 9 months production to 16 months. The application of sensor of the electric current in transducer carries out timing to alternating current machine with transducer, in the world each developed country is used generally already, and have the tendency that replaces dc timing. With transducer control electric machinery realizes timing, can save the electric energy of 10 ％ above. In transducer, the main effect of sensor of suddenly Er electric current is the high-power transistor with high protection. Answer as a result of the noise of sensor of suddenly Er electric current time is short at 1 μ S, accordingly, when occurrence overload short circuit, in brilliant complete canal did not reach limiting temperature before can dump, make transistor gets reliable protection, the I in right graph, R, S, T is sensor of suddenly Er electric current.
