Chotchinga chitetezo cholowetsa cha thermocouple chimatha kupatula ndikusintha zizindikiro za thermocouple (TC) m'malo oopsa kukhala zizindikiro za 4-20mA, ndikuzitulutsa kudera lotetezeka. Chotchinga chitetezochi chili ndi cold junction coin compensation yomangidwa mkati ndipo chitha kukonzedwa mwanzeru. Mtundu weniweni wa thermocouple ukhoza kukhazikitsidwa kudzera mu mapulogalamu apakompyuta. Uli ndi ntchito za alamu yosweka ya waya komanso alamu yosadziwika. Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odzipatula, magetsi olowera, ndi ma terminal otulutsa. "*" ikuyimira mtundu wolowera wa thermocouple, ndipo chitsanzo chenichenicho chikuyimiridwa ndi code (onani "Mtundu wa Chizindikiro Cholowetsa ndi Tebulo Lozungulira" kuti mudziwe zambiri).
Mitundu ya zizindikiro zolowera ndi kuchuluka kwa muyeso
| Khodi | Chitsanzo cha TC | Mulingo woyezera | Magawo ocheperako | Kulondola kwa kutembenuka |
| 1 | K | -200~1370℃ | 50℃ | 0.5℃/0.1% |
| 2 | S | -50~1760℃ | 500℃ | 1.5℃/0.1% |
| 3 | NDI | -140~1000℃ | 50℃ | 0.5℃/0.1% |
| 4 | J | -160~1200℃ | 50℃ | 0.5℃/0.1% |
| 5 | B | 250~1800℃ | 500℃ | 1.5℃/0.1% |
| 6 | T | -200~400℃ | 50℃ | 0.5℃/0.1% |
| 7 | R | -50~1760℃ | 500℃ | 1.5℃/0.1% |
| 8 | N | -200~1300℃ | 50℃ | 0.5℃/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.
