Chotchinga chachitetezo chodzipatula cha analog chomwe chili ndi ntchito yoteteza ma surge chimapereka mphamvu zodzipatula kwa ma transmitter awiri ndi atatu m'malo oopsa. Chizindikiro cha 4-20mA chomwe chimapangidwa ndi transmitter kapena gwero lamagetsi chimatumizidwa kuchokera kumalo oopsa kupita kumalo otetezeka, motero chimayendetsa katundu m'malo otetezeka. Kwa ma transmitter awiri kapena atatu amagetsi kapena zizindikiro zamagetsi, chotchinga chachitetezo ichi chimathandizira kulumikizana kwa ma signal a digito a Hart omwe ali pamwamba pa chizindikiro cha 4-20mA ndipo chili ndi ntchito ya alamu yosweka yamagetsi.
Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odziyimira pawokha, malo olowera, ndi malo otulutsira.
