Indlela yokulinganisa ye-thermocouple yegesi

Ixesha lokuphendula le-shiri-i-i-i-thermocoupleinzima kakhulu. Iimeko zovavanyo ezahlukeneyo zineziphumo ezahlukeneyo zokulinganisa kuba ichaphazeleka linqanaba lokutshintsha kwe-thermouple kunye nendawo ephakathi, kunye nexesha lokuphendula lobushushu lifutshane. Ukwenzela ukwenza ixesha lokuphendula le-thermal lemveliso ye-thermocouple, iMigangatho yeSizwe: Ixesha lokuphendula le-Thermal kufuneka lenziwe kwisixhobo esikhethekileyo sovavanyo lwamanzi. Iqondo lokuhamba kwamanzi lesixhobo kufuneka ligcinwe ngu-0.4 ± 0.05 m / s, kwaye iqondo lobushushu likuluhlu lwe-5-50 ° C. Ngexesha lokuvavanywa, kungabi ngaphezu kwe- ± 1% yobushushu. Ubunzulu obunzulu be-Thermocouple yi-150 mm okanye ubunzulu owenziwe (khetha ixabiso elincinci kwaye ubonise ingxelo yovavanyo).
Kuba esi sixhobo sinobunzima ngakumbi, iiyunithi ezimbalwa zinesixhobo esinjalo, ngoko ke uMgangatho weSizwe ubonelela ukuba umenzi uvunyelwe ukuba axoxe nabasebenzisi, kwaye ezinye iindlela zovavanyo zinokusetyenziswa.
Kuba i-thermocoupleples kuhlobo lwe-Ti-i-i-i-thermocouplezincinci kufutshane neqondo lobushushu legumbi, ixesha lokuphendula le-irmal alikho lula ukulinganisa iNdibano yeNdibano ye-elektrolitric esebenzisa iNdibano yeThermoode yeThermocouple ye-S-CEBISO ye-S-CEBISO, kwaye emva koko uvavanyo.

Xa uvavanyo, ukukhutshwa kwe-thermocouple kufuneka kurekhodwe kwi-T0.5 ehambelana neqondo lobushushu ngama-50%, ukuba kukho i-10% yexesha lokuphendula nge-9,3 kunye neqondo lokuphendula le-PH0.9. Ixesha lokuphendula elirekhodiweyo kufuneka libe lixabiso eliphakathi kweziphumo zovavanyo ezintathu. Iziphumo nganye yokulinganisa kufuneka ibe ngaphakathi kwi-10% yokuphambuka komndilili. Ukongeza, ixesha elifunekayo lokwenza ukuba utshintsho lwamaqondo obushushu kufuneka lungadli kwishumi le-T0.5 ye-TheRmocouple evavanyiweyo. Ukurekhoda ixesha lokuphendula kwesixhobo okanye isixhobo akufuneki sidlule kwishumi le-T0.5 yeli tyalai-i-i-i-thermocouple.
