Ma Pressure transmitters ndi zida zofunika zomwe zimagwiritsidwa ntchito poyezera, kuyang'anira ndi kuwongolera kusiyanasiyana kwa mpweya, zakumwa ndi madzi. Atha kutengapo gawo lofunikira pakuwonetsetsa chitetezo, kuchita bwino, komanso kudalirika kwa njira m'magawo ambiri azamakampani. Kumvetsetsa zomwe kutulutsa kwa ma transmitter ndikofunikira kwa akatswiri ndi ogwira ntchito omwe amadalira kuwerengera molondola pantchito yawo.
Ma transmitter amphamvu nthawi zambiri amasintha ma siginecha omwe amalandilidwa kuchokera ku sensor yophatikizika yophatikizika kukhala siginecha yayikulu yamagetsi yomwe pambuyo pake imatumizidwa ku control system (PLC/DCS) kuti iwunikire ndikuwongolera munthawi yeniyeni. Makamaka, mitundu yodziwika bwino yotulutsa ma siginecha ndi motere:
Zotulutsa Panopa:Mtundu waukulu womwe umatuluka ndi chizindikiro chapano, chomwe chimakhala ngati 4-20 mA loop pano. Zomwe zimatuluka zimakhala ndi ubale wofananira ndi kuchuluka kwa kuthamanga komwe kumawonjezeka molingana ndi kuwerenga kwamakasitomala. Mwachitsanzo, mizere yoyezera ya (0~10) bar ingatchule zero point ngati 4mA pomwe kukakamiza kwa 10bar kumafanana ndi 20mA kupanga graph yozungulira nthawiyo. Mtundu uwu umalola kutanthauzira kosavuta kwa mtengo wopanikizika ndipo umagwiritsidwa ntchito kwambiri m'mafakitale chifukwa cha mphamvu zake zotsutsana ndi phokoso lamagetsi.
Zotulutsa Pakompyuta: Ma transmitters anzeru amatha kutulutsa digito m'njira zolumikizirana mwanzeru monga HART, Modbus-RTU kapena ma protocol ena. Kutulutsa kwa digito kumabweretsa zabwino monga kulondola kwapamwamba, kusinthidwa kwapamalo ndi kuzindikira, zina zowonjezera zomwe zimatumizidwa ku PLS/DCS, s ndi kuchepetsa kutengeka kwa phokoso. Izi zotulutsa zanzeru zama digito zikuchulukirachulukira m'makina amakono opangira makina.
Kutulutsa kwa Voltage:Ma transmitters ena othamanga amatha kutulutsa mphamvu yamagetsi, nthawi zambiri mumayendedwe a 0-5V kapena 0-10V. Mtundu wotulutsa mphamvu yamagetsi ndi wocheperako poyerekeza ndi loop wapano koma ukhoza kukhala wothandiza makamaka pamapulogalamu omwe ma siginecha amavotera pamakina owongolera.
Kutulutsa pafupipafupi:Kutulutsa pafupipafupi kumatanthawuza kutembenuza kuwerengera mphamvu kukhala siginecha yama frequency. Ngakhale kuti ma frequency signal sagwiritsidwa ntchito kawirikawiri pama transmitters chifukwa cha kukwera mtengo komanso zovuta zaukadaulo, Zitha kukhala zopindulitsa pamapulogalamu ena omwe amafunikira kutumizirana mwachangu kwa data.
Mukasankha chizindikiro choyenera chotuluka, chidwi chidzaperekedwanso kuzinthu zina zomwe zingakhudze zotulukapo:
Kuwongolera:Kuwongolera koyenera ndikofunikira kuti muwerenge zolimba zolondola. Kuyeza kwa fakitale kuyenera kuchitidwa kuti zitsimikizire kuti zomwe zimatuluka zimagwirizana ndi kukakamiza kwenikweni koyezera m'njira yoyenera poyerekezera zomwe zimatuluka ndi mulingo wodziwika bwino ndikuwongolera pakafunika.
Kutentha:Kutentha kumatha kukhudza kulondola kwa zotulutsa. Kulipiritsa kutentha kwa fakitale kumatha kuthandiza kukonza kutentha komwe sikungachitike mozungulira, koma kutentha kwambiri kumatha kusokoneza magwiridwe antchito a transmitter. Ndikofunikira kusankha ma transmitter omwe adavotera kusiyanasiyana kwa kutentha komwe kumagwirira ntchito.
Kugwedezeka ndi Kugwedezeka:Kugwedezeka ndi kugwedezeka kumachitika m'magawo ena pakati pa mafakitale omwe angayambitse kuwerengeka kosakhazikika ndi kuwonongeka kwa chida. Ndikofunikira kusankha kamangidwe kolimba kosagwirizana ndi kugwedezeka ndikugwiritsa ntchito njira zochepetsera kugwedezeka kuti muteteze kukhulupirika kwa zida.
Katundu Wapakatikati:Chikhalidwe cha sing'anga choyezera chingakhudzenso zotuluka. Zinthu monga mamasukidwe akayendedwe, dzimbiri, kusiyanasiyana kwa zinthu komanso kukhalapo kwa tinthu ting'onoting'ono tating'onoting'ono titha kupangitsa kuti pakhale kupsinjika kwapang'onopang'ono. Kusankha mtundu wolondola wa ma transmitter ogwirizana ndi zinthu zina zamadzimadzi oyezera ndikofunikira kuti chida chizigwira bwino ntchito.
Mawonekedwe otulutsa ma siginecha kuchokera pamagetsi opatsirana ndi gawo lofunikira kwambiri pamachitidwe ake. Monga wopanga zida zodziwika bwino pantchito yowongolera njira kwazaka zopitilira 20,Shanghai Wangyuanimapereka zida zoyezera zotsimikizika komanso zodalirika zokhala ndi chidziwitso chochuluka pamitundu yonse yazizindikiro zotuluka kuchokera ku 4 ~ 20mA wamba komanso kulumikizana kwanzeru mpaka kutulutsa makonda. Ngati muli ndi funso kapena zofunikira pazotulutsa ma transmitter musazengereze kulumikizana nafe.
