Ikoreshwa ryinshi risanzwe ryerekana ibimenyetso byamashanyarazi muruganda ni ugukoresha 4-20mA DC kugirango wohereze analog.Impamvu yo gukoresha ibimenyetso byubu ni uko bitoroshye kubangamirwa, kandi kurwanya imbere kwinkomoko y'ubu ntibigira iherezo, kandi kurwanya insinga mu ruhererekane rw'ibizunguruka ntabwo bigira ingaruka ku kuri, kandi birashobora kwanduza amagana ya metero kumurongo usanzwe uhindagurika.Umupaka wo hejuru ni 20mA kubera ibisabwa bidashobora guturika: ingufu za spark zatewe no kuzimya amashanyarazi ya 20mA ntabwo zihagije gutwika gaze.Impamvu ituma imipaka yo hasi idashyirwa kuri 0mA nugushobora gutahura gutandukana: ntibizaba munsi ya 4mA mugihe gisanzwe.Iyo umurongo wohereza wacitse kubera ikosa, ikizunguruka kigenda kigabanuka kuri 0, na 2mA ikoreshwa nkigiciro cyo gutabaza.
