Mwachidule
Chotchinga chachitetezo cha analogi chodziyimira pawokha chokhala ndi chitetezo cha ma surgery chimapereka magetsi akutali kwa ma transmitter awiri - ndi atatu mawaya m'malo owopsa. Chizindikiro cha 4-20mA chopangidwa ndi transmitter kapena gwero lapano chimaperekedwa kuchokera kumalo owopsa kupita kumalo otetezedwa, motero amayendetsa katundu pamalo otetezeka. Kwa ma transmitters awiri kapena atatu kapena magwero aposachedwa, chotchinga chachitetezochi chimathandizira kulumikizana kwapawiri kwa chizindikiro cha digito cha Hart choyikidwa pa siginecha ya 4-20mA ndipo imakhala ndi alamu yosweka waya.
Izi zimafuna magetsi odziyimira pawokha, okhala ndi magetsi akutali, zolowetsa, ndi zotulutsa.
