Ma transmitter opanikizika ndi zida zofunika kwambiri zomwe zimagwiritsidwa ntchito poyesa, kuyang'anira ndikuwongolera kusinthasintha kwa kuthamanga kwa mpweya, zakumwa ndi madzi. Angathe kuchita gawo lofunikira pakuwonetsetsa kuti njira zikuyenda bwino, zikuyenda bwino, komanso kudalirika m'magawo osiyanasiyana amafakitale. Kumvetsetsa zomwe zimatuluka mu transmitter yopanikizika ndikofunikira kwa akatswiri ndi ogwiritsa ntchito omwe amadalira kuwerenga molondola kwa kuthamanga kwa magazi pantchito yawo.
Chotumizira mphamvu nthawi zambiri chimasintha chizindikiro cholandiridwa kuchokera ku sensa yolumikizidwa ya pressure kukhala chizindikiro chachikulu chamagetsi chomwe chimatumizidwa ku system yowongolera (PLC/DCS) kuti chiziwunika ndikuwongolera nthawi yeniyeni. Makamaka, mitundu yodziwika bwino ya kutulutsa chizindikiro ndi iyi:
Zotsatira Zamakono:Mtundu waukulu wa kutulutsa ndi chizindikiro chamagetsi, chomwe nthawi zambiri chimakhala ngati kuzungulira kwamagetsi kwa 4-20 mA. Kutulutsa kumakhala ndi ubale wolunjika ndi kuthamanga komwe kumawonjezeka mofanana ndi kuwerenga kwa kuthamanga. Mwachitsanzo, mulingo woyezera wa (0~10)bar ukhoza kutchula zero point ngati 4mA pomwe kuthamanga kwa 10bar kumafanana ndi 20mA kupanga mzere wolunjika pa nthawi yonse. Mtundu uwu umalola kutanthauzira kosavuta kwa kuthamanga ndipo umagwiritsidwa ntchito kwambiri m'mafakitale chifukwa cha kulimba kwake motsutsana ndi phokoso lamagetsi.
Zotulutsa za digito: Ma transmitter anzeru amatha kupereka kutulutsa kwa digito m'njira zosiyanasiyana zolumikizirana mwanzeru monga HART, Modbus-RTU kapena ma protocol ena. Zotulutsa za digito zimabweretsa zabwino monga kulondola kwambiri, kusintha ndi kuzindikira komwe kumachitika pamalopo, zambiri zowonjezera zomwe zimatumizidwa ku PLS/DCS, s, komanso kuchepetsa kukhudzidwa ndi phokoso. Zotulutsa zanzeru izi za digito zikuchulukirachulukira m'makina amakono odziyimira pawokha.
Kutulutsa kwa Voltage:Ma transmitter ena a pressure amatha kupereka mphamvu yotulutsa mphamvu, nthawi zambiri imakhala pakati pa 0-5V kapena 0-10V. Mtundu wotulutsa mphamvu yamagetsi ndi wocheperako poyerekeza ndi kuzungulira kwamagetsi koma ungakhale wothandiza makamaka m'magwiritsidwe ntchito komwe ma signal amagetsi amakondedwa pamakina owongolera.
Kutulutsa Kwafupipafupi:Kutulutsa kwa ma frequency kumatanthauza kusintha kuwerengera kwa kupanikizika kukhala chizindikiro cha ma frequency. Ngakhale kuti chizindikiro cha ma frequency sichigwiritsidwa ntchito kawirikawiri m'ma transmitter opanikizika chifukwa cha mtengo wokwera komanso zovuta zaukadaulo, chingakhale chothandiza kwambiri m'magwiritsidwe ntchito enaake komwe kutumiza deta mwachangu kumafunika.
Mukasankha chizindikiro choyenera chotulutsa, muyeneranso kuganizira zinthu zina zomwe zingakhudze kutulutsa kwake:
Kulinganiza:Kuyeza bwino ndikofunikira kuti pakhale kuwerengera kolondola kwa kuthamanga kwa magazi. Kuyeza kwa fakitale kuyenera kuchitika kuti zitsimikizire kuti mphamvu yotulutsa ikugwirizana ndi mphamvu yeniyeni yoyezera mphamvu moyenera poyerekezera mphamvu yotulutsa ya chotumizira ndi muyezo wodziwika bwino wa kuthamanga kwa magazi ndikuyisintha ngati pakufunika kutero.
Zotsatira za Kutentha:Kutentha kungakhudze kulondola kwa kutulutsa. Kuchepetsa kutentha kwa fakitale kungathandize kukonza kutentha kosafunikira komwe kumazungulira malo, koma kutentha kwambiri kumatha kukhudzabe magwiridwe antchito a chotumizira. Ndikofunikira kusankha chotumizira chomwe chili ndi chiwerengero cha kutentha komwe chimagwiritsidwa ntchito.
Kugwedezeka ndi Kugwedezeka:Kugwedezeka ndi kugwedezeka kumachitika m'magawo ena pakati pa mafakitale zomwe zingayambitse kusinthasintha kwa mawerengedwe ndi kuwonongeka kwa chipangizocho. Ndikofunikira kusankha kapangidwe kake kolimba kosagwedezeka ndikugwiritsa ntchito njira zofunikira zochepetsera kugwedezeka kuti muteteze umphumphu wa chipangizocho.
Katundu Wapakati:Kapangidwe ka njira yoyezera kangakhudzenso kutuluka kwa chinthucho. Zinthu monga kukhuthala, dzimbiri, kusiyana kwa zinthu ndi kupezeka kwa tinthu tomwe timapachikidwa kungayambitse kusinthasintha kwa kuwerenga kwa mphamvu. Kusankha mtundu woyenera wa chotumizira chomwe chimagwirizana ndi makhalidwe enaake a madzi oyezera ndikofunikira kuti chipangizocho chigwire ntchito bwino.
Mitundu ya kutulutsa kwa chizindikiro kuchokera ku chotumizira mphamvu ndi gawo lofunika kwambiri pakugwira ntchito kwake. Monga wopanga zida wodziwa bwino ntchito yowongolera njira kwa zaka zoposa 20,Shanghai Wangyuanimapereka zida zoyezera zotsimikizika komanso zodalirika komanso chidziwitso chochuluka pa mitundu yonse ya zizindikiro zotulutsa kuyambira 4 ~ 20mA wamba komanso kulumikizana mwanzeru mpaka zotulutsa zomwe mwasankha. Ngati muli ndi funso lililonse kapena zofunikira pa zotulutsa zotumizira musazengereze kulumikizana nafe.
