Kuyeza kutentha ndi gawo lofunika kwambiri pakuwongolera njira m'mafakitale osiyanasiyana monga kupanga mankhwala, mafuta ndi gasi, mankhwala, ndi kupanga chakudya. Sensor ya kutentha ndi chipangizo chofunikira chomwe chimayesa mwachindunji mphamvu ya kutentha ndikumasulira kayendedwe ka kutentha kukhala zizindikiro zamagetsi kuti chikwaniritse kuyang'anira kosalekeza ndi kusonkhanitsa deta ngati njira ikugwira ntchito mkati mwa kuchuluka kwa kutentha komwe kwafotokozedwa. Monga tafotokozera muKodi tingasinthe RTD ndi Thermocouple?, zinthu zomwe zimazindikira kutentha zimaphatikiza RTD ndi TR, zomwe zimakhala bwino kwambiri pamlingo wosiyana komanso chizindikiro cha ohm/mV chotuluka padera.
Ngakhale kuti sensa yotenthetsera yakhala ikugwiritsidwa ntchito kwa nthawi yayitali ngati chida chofunikira kwambiri chojambulira deta ya kutentha yokha, imatha kuphatikizidwa ku makina otumizira deta mu ntchito zowongolera njira. Sensa yotenthetsera ndi chipangizo cholumikizira chomwe chimalumikizana ndi RTD kapena sensa ya thermocouple, chimakulitsa ndikukhazikitsa chizindikiro cha sensa ku chizindikiro chamagetsi chokhazikika, kenako chimatuluka kupita ku zamagetsi zolandirira. Zizindikiro zokhazikika zomwe zimawerengedwa kuti zigwiritsidwe ntchito ndi makina owongolera kumbuyo monga PLC kapena DCS nthawi zambiri zimakhala analog 4-20mA ndi kulumikizana kwa digito kwa Hart kapena Modbus.
Ubwino wogwiritsa ntchito chotumizira kutentha
Ngakhale masensa otentha akadali ofunikira kwambiri pakupeza deta, ma transmitter amawonjezera magwiridwe antchito awo ndi zinthu zingapo:
Kukhazikika kwa chizindikiro:Chizindikiro chamagetsi chopanda pake chomwe chimapangidwa ndi sensa yotenthetsera yokha ndi chofooka ndipo chimakhudzidwa ndi phokoso lamagetsi ndi kusokonezedwa komanso kuwonongeka kwa chizindikiro patali. Poyerekeza, chizindikiro cha 4-20mA cholamulidwa ndi transmitter chimakhala cholimba kwambiri ndipo chimapangitsa kuti kukana kusokonezedwa ndi maginito amagetsi kukhale kolondola komanso kodalirika. Kuyika mzere ndi kulipira zotulutsa za sensa zosaphika kumapangitsa kutumiza deta kupita ku chipangizo chowongolera kukhala kolondola komanso kodalirika.
Kugwirizana ndi kuphweka:Gawo lotumizira kutentha limagwirizana ndi masensa a RTD ndi thermocouple. Kugwiritsa ntchito zinthu zosiyanasiyana zowunikira kungavomerezedwe. Kusinthasintha kumeneku kumathandiza kuti sensa igwiritsidwe ntchito kwambiri pamitundu yonse ya kuyeza kutentha ndi zofunikira zosiyanasiyana za kutalika ndi kuchuluka kwa sensa. Chizindikiro cha pamalopo chikhoza kuyikidwa pa bokosi la terminal kuti chipereke kuwerenga ndi kukonza kosavuta kwapafupi.
Kuphatikiza bwino kwa machitidwe:Kutulutsa kwa transmitter kokhazikika kumathandiza kuphatikiza bwino ndi machitidwe owongolera monga programmable logic controller (PLC) ndi distributed control system (DCS). Kulankhulana kwa digito kumathandiza kuyang'anira deta nthawi yeniyeni komanso kusintha magawo, kuchepetsa kufunikira kwa mwayi wofikira malo oopsa kapena ovuta kufikako. Kukonzanso malo kudzera mu mawonekedwe a digito kumakhala kosavuta ndipo kumachepetsa nthawi yogwira ntchito poyerekeza ndi kugwiritsa ntchito pamanja.
Shanghai Wangyuanwakhala akugwira ntchito yopanga ndi kupereka zida zoyezera kwa zaka zoposa 20. Chidziwitso chathu chambiri chaukadaulo komanso chidziwitso chathu chapadera chimatithandiza kupereka mayankho owongolera kutentha omwe akukwaniritsa zosowa zanu. Ngati pali mafunso ndi zofunikira zokhudzana ndi sensa ya kutentha ndi chotumizira, chonde musazengereze kutilumikiza.
