IJeoro ibonelela ngeendidi ezahlukeneyo zoThutho lobushushu
Abathumeli abalungisekayo abadluliseli kuphela iimpawu eziguquliweyo ezivela kwi-thermometers yokumelana (RTD) kunye ne-thermocouples (TC), ziphinde zidlulise ukuchasana (Ω) kunye neempawu ze-voltage (mV).Ukuze ufumane ukuchaneka komlinganiselo ophezulu, iimpawu zomgca walo lonke uhlobo lwenzwa zigcinwa kwi-transmitter.Kwinkqubo yokwenziwa kwe-automation imigaqo emibini yomlinganiselo weqondo lobushushu iziqinisekisile njengomgangatho:
I-RTD - Izixhobo zokujonga ubushushu bokumelana
Inzwa ye-RTD itshintsha ukuxhathisa kombane kunye nokutshintsha kweqondo lokushisa.Zikulungele umlinganiselo wamaqondo obushushu aphakathi kwe -200 °C kunye ne-approx.I-600 °C kwaye ivelele ngenxa yokuchaneka komlinganiselo ophezulu kunye nokuzinza kwexesha elide.Isixhobo soluvo esisetyenziswa rhoqo yiPt100.
TC - Thermocouples
I-thermocouple licandelo elenziwe ngeentsimbi ezimbini ezahlukeneyo ezidityaniswe enye kwenye ekupheleni.IiThermocouples zilungele umlinganiselo wobushushu kuluhlu lwe-0 °C ukuya +1800 °C.Zimi ngaphandle ngenxa yexesha lokuphendula ngokukhawuleza kunye nokumelana nokungcangcazela okuphezulu.
