Iyo inonyanya kushandiswa yakajairwa analog yemagetsi chiratidzo muindasitiri ndeye kushandisa 4-20mA DC ikozvino kufambisa analog.Chikonzero chekushandisa chiratidzo chemazuva ano ndechekuti hazvisi nyore kupindira, uye kupikisa kwemukati kwechitubu chemazuva ano hachiperi, uye kupikisa kwetambo mumutsara mumucheka hakukanganisi kurongeka, uye inogona kutumira mazana. yemamita pawaya yakajairika yakamonyoroka.Muganho wepamusoro ndeye 20mA nekuda kwechinoputika-chinongedzo chinodiwa: iyo spark simba inokonzerwa ne-on-off ye20mA ikozvino haina kukwana kupisa gasi.Chikonzero nei muganho wakaderera usina kuiswa ku0mA kukwanisa kuona kubviswa: haizove yakaderera pane 4mA panguva yekushanda kwakajairika.Kana tambo yekufambisa yatyorwa nekuda kwekukanganisa, loop ikozvino inodonha kusvika ku0, uye 2mA inowanzoshandiswa seyekubvisa alarm kukosha.
