Batho ba bangata hangata ba fosa li-transmitters tsa khatello le li-sensor tsa khatello tse tšoanang, tse emelang li-sensor. Ha e le hantle, li fapane haholo.
Sesebelisoa sa ho lekanya sa motlakase ka har'a sesebelisoa sa ho lekanya khatello se bitsoa khatello ea maikutlo. Li-sensor tsa khatello hangata li entsoe ka li-sensor tse elastic le li-sensor tsa ho falla.
1. Mosebetsi oa "elastic sensitive element" ke ho etsa hore khatello e lekantsoeng e sebetse sebakeng se itseng ebe e e fetola ho falla kapa khatello, ebe e e fetola hore e be lets'oao la motlakase le amanang le khatello ka ntho e 'ngoe ea bohlokoa ea ho falla kapa tekanyo ea khatello. Ka linako tse ling mesebetsi ea likarolo tsena tse peli e kopantsoe, joalo ka "solid-state stress sensor" ho sensor ea piezoresistive.
2. Khatello ke parameter ea bohlokoa ea ts'ebetso ts'ebetsong ea ts'ebetso le liindasteri tsa lifofane, lifofane le ts'ireletso ea naha. Ha e hloke feela ho emisa tekanyo e potlakileng le e matla, empa hape e bonts'a le ho rekota liphetho tsa tekanyo. The automation ea lihlahisoa tse kholo tsa oli, limela tsa lik'hemik'hale, limela tsa matla le limela tsa tšepe le tsa tšepe le tsona li hloka ho fetisetsa litekanyetso tsa khatello ka nako e telele, le ho kopa ho fetola khatello le likarolo tse ling, tse kang mocheso, phallo le viscosity, hore e be lipontšo tsa digital le li romele khomphuteng.
3. Sensor ea khatello ea maikutlo ke mofuta oa kutlo o nkoang e le oa bohlokoa haholo 'me o ntlafatsoa ka potlako. Mokhoa oa nts'etsopele ea sensor ea khatello ke ho ntlafatsa lebelo le matla la ho arabela, ho nepahala le ho ts'epahala, le digitization e felletseng le bohlale. Li-sensor tse tloaelehileng tsa khatello li kenyelletsa sensor ea khatello ea capacitive, sensor ea khatello ea maikutlo e feto-fetohang, sensor ea khatello ea holo, sensor ea khatello ea fiber, sensor ea khatello ea resonant, jj.
Ho na le mefuta e mengata ea li-transmitters. Li-transmitter tse sebelisoang lisebelisoa tsa taolo ea indasteri haholo-holo li kenyelletsa transmitter ea mocheso, transmitter khatello, phallo transmitter, current transmitter, voltage transmitter joalo-joalo.
1. Transmitter e lekana le amplifier ea matšoao. Transmitter ea AC220V eo re e sebelisang e fana ka voltage ea dc10v ea borokho ho sensor, ebe e amohela lets'oao la maikutlo, ea holisa le ho hlahisa 0V ~ 10V voltage kapa lets'oao la hajoale. Ho boetse ho na le li-transmitters tse nyane tsa DC24V, tse batlang li lekana le li-sensor mme ka linako tse ling li kentsoe hammoho. Ka kakaretso, transmitter e fana ka matla ho sensor le ho holisa lets'oao. Sensor e bokella feela matšoao, joalo ka strain gauge, e fetolang lets'oao la phalliso hore e be lets'oao la ho hanyetsa. Ha e le hantle, ho na le li-sensor tse se nang motlakase, tse kang li-thermocouples le li-ceramics tsa piezoelectric, tse atisang ho sebelisoa.
2. Re sebelisitse mefuta e fapaneng ea li-sensor tsa khatello, empa transmitter ha e so ka e nkeloa sebaka. Sensor ea khatello e lemoha lets'oao la khatello, hangata e bua ka mitha ea mantlha. Transmitter ea khatello e kopanya mitha ea mantlha le mitha ea bobeli, 'me e fetolela lets'oao le bonoeng hore e be matšoao a tloaelehileng a 4-20, 0-20 Ma kapa 0-5V, 0-10V, o ka utloisisa sena ka ho hlaka: sensor "e utloa" e fetisitsoeng. signal, 'me transmitter ha e utloe feela, empa hape "e fetoha" lets'oao le tloaelehileng ebe e "romela" ntle.
Sensor ea khatello hangata e bua ka ntho e hlokolosi e fetolang lets'oao le fetotsoeng la khatello hore e be lets'oao le ts'oanang la khanyetso kapa lets'oao la matla, joalo ka piezoresistive element, piezocapacitive element, joalo-joalo. Pressure transmitter hangata e bua ka sete e felletseng ea yuniti ea potoloho bakeng sa ho metha khatello e entsoeng ka likarolo tse nang le khatello ea maikutlo le potoloho ea boemo. Ka kakaretso, e ka ntša ka kotloloho lets'oao le tloaelehileng la motlakase kapa lets'oao la hajoale kamanong ea mohala le khatello ea ho bokelloa ka kotloloho ke lisebelisoa, PLC, karete ea ho reka le lisebelisoa tse ling.
