Chotchinga chachitetezo chodzipatula cha RTD chimatha kusintha ma waya awiri kapena atatu ma waya thermistor (RTD) m'malo owopsa kukhala ma siginecha apano a 4-20mA ndikuwatulutsa kumalo otetezedwa. Ikhoza kukhazikitsidwa mwanzeru, ndipo mtundu weniweni wa kukana kutentha ukhoza kukhazikitsidwa kudzera pa mapulogalamu apakompyuta. Ili ndi ntchito za alamu yosweka waya komanso ma alarm akunja.
Izi zimafuna magetsi odziyimira pawokha, okhala ndi magetsi akutali, zolowetsa, ndi zotulutsa.
"*" imayimira mtundu wolowera wa chotenthetsera, ndipo choyimiracho chimayimiridwa ndi code (onani "Mtundu wa Chizindikiro Cholowetsa ndi Table Range" kuti mumve zambiri).
