Na'urar firikwensin ABS.
Ana amfani da firikwensin Abs a cikin motar ABS (Tsarin Birki Mai Hana Kullewa). A cikin tsarin ABS, ana sa ido kan saurin ta hanyar firikwensin inductive. Firikwensin abs yana fitar da saitin siginar lantarki ta AC ta hanyar aikin zoben gear wanda ke juyawa tare da ƙafafun, kuma mita da girmansa suna da alaƙa da saurin ƙafafun. Ana aika siginar fitarwa zuwa sashin sarrafa lantarki na ABS (ECU) don gano saurin ƙafafun a ainihin lokaci.

Na biyu, gwajin juriya mai ƙarancin zafin jiki na firikwensin ciki (abs sensor)
A ajiye firikwensin a zafin digiri 40 na Celsius na tsawon awanni 24 don gwada ko firikwensin a cikin ciki zai iya biyan buƙatun aikin lantarki da rufewa na amfani na yau da kullun
Me yasa na'urar firikwensin ciki ke da sauƙin karyewa
Dalilan da yasa na'urar firikwensin ABS ke da sauƙin lalacewa sun haɗa da ɓangaren shigar da shi, layin ya yi laushi da kuma ingancin na'urar firikwensin kanta. Cikakkun bayanai sune kamar haka:
An rufe ɓangaren jijiya: lokacin da ɓangaren jijiya na na'urar firikwensin ABS ya rufe da datti, ƙura ko wasu sassan waje, zai tsoma baki ga fitowar siginar na'urar firikwensin, wanda hakan zai sa kwamfutar ba ta iya tantance saurin da ya dace ba, wanda zai shafi aikin tsarin birki na yau da kullun.
