Kuyeza kutentha ndi gawo lofunikira pakuwongolera njira m'mafakitale osiyanasiyana monga kupanga mankhwala, mafuta ndi gasi, mankhwala, ndi kupanga chakudya. Sensa ya kutentha ndi chipangizo chofunikira chomwe chimayesa mphamvu ya kutentha ndikumasulira kutentha kwa magetsi kuti akwaniritse kuwunika kosalekeza ndi kusonkhanitsa deta ngati ndondomeko ikugwira ntchito mkati mwa kutentha komwe kumatanthauzidwa. Monga tafotokozera muKodi Titha Kusintha RTD ndi Thermocouple?, zinthu zodziwika bwino za kutentha zimaphatikizapo RTD ndi TR, zomwe zimapambana mumiyeso yosiyana ndi kutulutsa chizindikiro cha ohm/mV padera.
Ngakhale sensa ya kutentha kwa nthawi yayitali yakhala ngati chida chofunikira chojambulira deta yotentha, imatha kuphatikizidwa ndi ma transmitter pamapulogalamu owongolera. Temperature transmitter ndi chipangizo chapakati chomwe chimalumikizana ndi RTD kapena thermocouple sensor, imakulitsa ndikusintha chizindikiro cha sensa kupita ku siginecha yokhazikika yamagetsi, kenako imatuluka polandila zamagetsi. Zizindikiro zowerengeka zomwe zimawerengedwa kuti zigwiritsidwe ntchito ndi makina owongolera kumbuyo monga PLC kapena DCS nthawi zambiri amakhala analogi 4-20mA ndi kulumikizana kwa digito Hart kapena Modbus.
Ubwino wogwiritsa ntchito cholumikizira kutentha
Ngakhale zowunikira kutentha zimakhalabe zofunika pakupeza deta, ma transmitter amakweza ntchito yawo mwakusintha kangapo:
Kutsimikizika kwa chizindikiro chokwezedwa:Chizindikiro chochepa chamagetsi mudera lopangidwa ndi sensa ya kutentha yokha ndi yofooka ndipo imatha kukhudzidwa ndi phokoso lamagetsi ndi kusokonezedwa komanso kuwonongeka kwa chizindikiro pamtunda wautali. Poyerekeza, siginecha ya 4-20mA yoyendetsedwa ndi ma transmitter imakhala yolimba kwambiri ndipo imathandizira kukana kusokonezedwa ndi ma elekitiroma. Linearization ndi chipukuta misozi yaiwisi sensa linanena bungwe kumapangitsa kufala deta cholozera chipangizo chowongolera molondola ndi odalirika.
Kugwirizana & kumasuka:Module yotumizira kutentha imagwirizana ndi ma sensor a RTD ndi thermocouple. Kugwiritsa ntchito zinthu zingapo zomveka kumathanso kuvomerezedwa. Kusinthasintha kumathandizira kuti ma transmitter azigwiritsidwa ntchito kwambiri pamitundu yonse ya kuyeza kwa kutentha komwe kumakhala ndi nthawi zosiyanasiyana komanso kuchuluka kwa sensor. Chizindikiro chapamalo chitha kuyikidwa pabokosi la terminal lomwe limapereka zowerengera zomveka bwino zakomweko komanso masinthidwe.
Kuphatikiza kwadongosolo:Kutulutsa kwa ma transmitter okhazikika kumathandizira kuphatikiza kosagwirizana ndi makina owongolera monga programmable logic controller (PLC) ndi distributed control system (DCS). Kuyankhulana kwapa digito kumathandizira kuyang'anira deta nthawi yeniyeni ndikusintha magawo, kuchepetsa kufunikira kwa thupi kumalo owopsa kapena ovuta kufika. Kukonzanso kumunda kudzera mu mawonekedwe a digito kumakhala kosavuta komanso kumachepetsa nthawi yopumira poyerekeza ndi ntchito yamanja.
Shanghai Wangyuanwakhala akugwira ntchito yopanga ndi ntchito zoyezera zida kwa zaka zopitilira 20. Chidziwitso chathu chambiri chaukadaulo komanso zochitika zakumunda zimatipatsa mwayi wopereka njira zowongolera kutentha zomwe zikugwirizana ndi zosowa zanu. Ngati pali mafunso ndi zofuna zokhudzana ndi sensa ya kutentha ndi ma transmitter, chonde musazengereze kutilumikizana nafe.
