Chidule
Chotchinga chitetezo cha RTD cholowetsa chodzipatula chimatha kusintha ma signal awiri a waya kapena atatu a waya (RTD) m'malo oopsa kukhala ma signal a 4-20mA ndikuzitulutsa kudera lotetezeka. Chikhoza kukonzedwa mwanzeru, ndipo kuchuluka kwenikweni kwa kukana kutentha kumatha kukhazikitsidwa kudzera mu mapulogalamu apakompyuta. Chili ndi ntchito za alamu yosweka ndi alamu yosadziwika.
Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odziyimira pawokha, malo olowera, ndi malo otulutsira.
"*" ikuyimira mtundu wolowera wa thermistor, ndipo chitsanzo chenichenicho chikuyimiridwa ndi khodi (onani "Mtundu wa Chizindikiro Cholowera ndi Tebulo Losiyanasiyana" kuti mudziwe zambiri).
Mitundu ya zizindikiro zolowera ndi kuchuluka kwa muyeso

| 7 | Ni1000 | -60~250℃ | 20℃ | 0.2℃/0.1% |
Chitsanzo: pamene zolowetsa zili ziwiri zolowetsa ndi K-couple, kutentha kwake kuli 0 ~ 1200℃, zotulutsa ziwiri 4 ~ 20mA, magetsi 20 ~ 35VDC, ndiye kuti chitsanzocho chiyenera kukhala PHD-22TT-1111 (0 ~ 1200℃).
Kompyuta ikhoza kuyika miyeso pamlingo wa 0 ~ 1200℃ womwe watchulidwa.
