Bincika ko nau'in firikwensin PT100 yana aiki mai gamsarwa.
Ana iya raba firikwensin PT100 zuwa wayoyi 2, wayoyi 3 da yanayin wayoyi 4 bisa ga yanayin aikace-aikacen daban-daban (kamar yadda aka nuna a ƙasa). A cikin wannan takarda, za a yi amfani da firikwensin PT100 mai waya 3 don kwatanta hanyar dubawa.
A matsayin babban madaidaicin madaidaicin firikwensin zafin jiki, firikwensin zafin jiki na PT100 yana da fa'idodin aikace-aikacen a cikin tsarin sarrafa sarrafa kansa na masana'antu, kayan aikin dakin gwaje-gwaje, kayan aikin likitanci, da dai sauransu. Amsa da sauri, daidaito mai kyau, kwanciyar hankali mai kyau da sauran halaye sun sa ya zama muhimmin sashi na filin auna zafin masana'antu.
Siffar firikwensin zafin jiki na platinum thermal resistor shine cewa ƙimar juriya tana ƙaruwa tare da haɓakar zafin jiki, kuma juriya yana raguwa tare da raguwar zafin jiki.
Sabili da haka, ana iya yanke hukunci da sauri ta hanyar auna juriya tare da multimeter. Da farko za ku iya cire haɗin wayar na platinum thermal resistor a cikin madauki, sannan ku yi amfani da matsayi na 200 ohm na kewayon juriya na multimeter, sannan ku nemo wayoyi guda biyu don auna ƙimar juriya. Idan juriyar wayoyi biyu shine 0 kuma juriya na sauran wayoyi biyu shine kusan 100 ohms, al'ada ce. Idan ba haka ba, platinum thermal resistor yana buƙatar maye gurbinsa.
