Ingaba i-PT100 sensor isebenza njani?

Umfanekiso wePT100inzwa yokushisa yokumelana nomgaqo wayo wokusebenza usekelwe kwinguqu yokumelana nomqhubi kunye nobushushu. I-PT100 yenziwe ngeplatinam ecocekileyo kwaye inozinzo oluhle kunye nomgca, ngoko isetyenziselwa ukulinganisa ubushushu. Kwi-degrees zero Celsius, ixabiso lokumelana ne-PT100 yi-100 ohms. Njengoko iqondo lokushisa linyuka okanye liyancipha, ukuchasana kwayo kwandisa okanye kuncipha ngokufanelekileyo. Ngokulinganisa ixabiso lokumelana ne-PT100, ubushushu bendawo yayo bunokubalwa ngokuchanekileyo.
Xa i-sensor ye-PT100 ihamba ngokuqhubekayo, ukuphuma kwayo kwamandla kuhambelana nokutshintsha kweqondo lokushisa, ngoko ubushushu bunokulinganiswa ngokungathanga ngqo ngokulinganisa i-voltage. Le ndlela yokulinganisa ibizwa ngokuba yi "voltage output type" yokulinganisa ubushushu. Enye indlela yokulinganisa eqhelekileyo "uhlobo lwemveliso yokumelana", olubala ubushushu ngokulinganisa ixabiso lokumelana ne-PT100. Kungakhathaliseki ukuba yeyiphi indlela esetyenzisiweyo, i-sensor ye-PT100 inikeza imilinganiselo yokushisa echanekileyo kwaye isetyenziswa ngokubanzi kwiindidi ezahlukeneyo zokulawula ukushisa kunye nokubeka iliso kwizicelo.
Ngokubanzi, i-sensor ye-PT100 isebenzisa umgaqo wokumelana nomqhubi oguqukayo kunye neqondo lokushisa ukulinganisa ngokuchanekileyo ubushushu ngokulinganisa ukuchasana okanye i-voltage, ukubonelela ngeziphumo ezichanekileyo zomlinganiselo weqondo lokushisa kwiinkqubo ezahlukeneyo zokulawula ukushisa kunye nokubeka iliso.
