Kazhinjitransmittersvakaiswa panzvimbo, uye zvikwangwani zvavo zvinobuda zvinoendeswa kuimba yekutonga, uye kuwanikwa kwemagetsi kunobva mukamuri rekutonga. Pane dzimwe nzira mbiri dzekutapurirana uye simba rekugovera iyo transmitter:
(1) mana-waya system
Simba remagetsi uye chiratidzo chekuburitsa chinotapurwa nemayira maviri zvichiteerana, uye iyo yambiro nzira inoratidzwa mumufananidzo 2.3. Serningters inonzi ina-waya transmitters. Iyo Transmister yeDDZ-ⅱ Series Insturts Iyi Inguva Ino Ine Wiring More. Simba remagetsi rinogona kunge riri (220V) kana DC (24v), uye chiratidzo chekubuda chinogona kunge chakafa zero (0-10ma) kana live zero (4-20ma).
Mufananidzo 2.3 mana-waya kutapurirana
(1) maviri-waya system
Kune maviri-waya transmitter, kune waya mbiri chete dzakabatana neye transmitter, uye awa maviri aya anotumira iyo Simba Simba uye inoburitsa chiratidzo panguva imwe chete, sezvakaratidzwa mumufananidzo 2.4. Zvinogona kuoneka kuti simba rekupa, transmitter uye muridzi kurwisa rakabatana mune dzakateedzana. Kana iyo yakayerwa paramende inoshanduka, kupokana kwakaenzana kweshanduko inoshanduka nenzira kwayo, saka zvazvino kuyerera kuburikidza nehuremu zvinoshandukawo.
Mufananidzo 2.4 maviri-waya kutapurirana
Maviri-waya transmitters anofanira kusangana nemamiriro ezvinhu anotevera:
①Temakero akajairika aripo razvino weTransmitter anofanira kuve akaenzana kana kushoma pane kukosha kushoma kwechiratidzo chazvino
, Ndizvozvo
Sezvo rondedzero yemagetsi uye mutsara wesina chiratidzo zvakajairika, simba rinopihwa kune transmitter neye simba rinopihwa nechiratidzo chazvino. Kana iyo yekubudiswa yazvino ye transmitter iri pane yakaderera muganho, inofanira kuve nechokwadi chekuti iyo Semiconductor zvishandiso mukati mayo inogona kuramba ichishanda zvakajairika.
Naizvozvo, iyo yakaderera muganho kukosha kwechiratidzo chazvino haigone kuve yakaderera. Nekuti pane yakaderera muganho wekubuda kweiyo transmitter, iyo Semiconductor chishandiso chinofanira kuve neyakajairika mashandiro ekushandisa, uye kuwanwa kwezvinhu zvakajairika kunofanirwa kupihwa nekupa simba, saka chiratidzo chazvino chinofanira kunge chine zero zero zero. Iyo International Yakabatana Chiratidzo Chekuratidzira inogamuchira 4-20madc, iyo inogadzira mamiriro ekugadzirwa kwemaviri-waya transmitters.
②Temamiriro eVoltage yerwendo rwekushandira kazhinji ndeye
Mune formula:
ndiyo yekubuditsa voltage yeturansmitter;
ndiko kushoma kukosha kwesimba rekuisa voltage;
ndiwo muganho wepamusoro wezvekubudira razvino, kazhinji 20ma;
ndiko kudzikisira kwakanyanya kukanganisa kukosha kweturansmitter;
ndiyo kukosha kwekupokana kwe waya yekubatanidza.
Iyo maviri-waya transmitter inofanira kuve inogadziriswa neiyo imwe DC simba reWindow. Iyo inonzi imwe chete isina simba simba rinoreva kuti simba rekugovera ne zero zero sezvinogona kuita sepfungwa yekutanga, pane iyo yakanaka uye yakaipa simba rekupa symmetrial kune zero voltage. Iyo inobuda voltage u ye transmitter yakaenzana nemusiyano uripo pakati peSower Supply Voltage uye yekudonha kweiyo yekubuditsa razvino uye kupikisa r ye waya yekutumira. Kuti uve nechokwadi chekushanda kwakajairwa kweshanduro ye transmitter, iyo yekuburitsa voltage kukosha kunogona kungoshanduka mukati menguva shoma. Kana kurwisa kwemutoro kuchiwedzera, iyo simba rekuisa voltage inoda kuwedzerwa; Zvikasadaro, vhesi yekuisa simba inogona kuderera; Kana iyo simba risina simba voltage inoderera, kuramba kwemutoro kunoda kuderera; Zvikasadaro, kurwisa mutoro kunogona kuwedzera.
③Imasimba mashoma anoshanda kune transmitter yekushanda zvakajairika
Sezvo simba remagetsi emagetsi-maviri transmitter idiki kwazvo, uye mutoro wekuvhomora zvinochinja zvakanyanya neyekuburitsa zvazvino uye kurodha kupokana, iyo yekubatira voltage yeiyo chikamu chega chega chitsva chinoshanduka zvikuru. Naizvozvo, kana uchigadzira transmitter miviri, inodikanwa kuti ishandise yakaderera-simba rakabatanidzwa mashandiro emushonga amplifier uye isa iyo yekukanda-simbisa yekubatanidza uye kuita kwakashata kwekuita zvakanaka.
Iwo maviri-waya transmitter ane zvakawanda zvakanakira, izvo zvinogona kuderedza zvakanyanya mutengo wemushini, uye unokodzera kuchengetedzwa uye kuchengetedzwa kwekuputika. Naizvozvo, nyika zhinji dziri munyika parizvino vanoshandisa maviri-waya transmitters.
