Chidule
Chotumiza kutentha cholowetsa cha Thermocouple chimatha kudzipatula ndikusintha
chizindikiro cha DC kuchokera ku thermocouple (TC) kupita ku chizindikiro cha DC. Chogulitsachi
ili ndi ntchito yolumikizira malo ozizira ndipo imatha kukhazikitsidwa
mwanzeru. Mtundu weniweni wa thermocouple ukhoza kukhazikitsidwa kudzera
mapulogalamu apakompyuta. . Ili ndi ntchito ya alamu yoletsa kutsekedwa ndi
ntchito ya alamu yomwe ili kutali.
Chogulitsachi chikuyenera kuyendetsedwa pachokha, ndipo magetsi ayenera kugwiritsidwa ntchito,
Malo olowera ndi otulutsira zinthu amachotsedwa.

| Lowetsani | |
| Chizindikiro cholowera | Zizindikiro za K, S, E, J, B, T, R, N TC (onani "Mtundu wa Chizindikiro Cholowera ndi Tebulo Losiyanasiyana" kuti mudziwe zambiri) |
| Kuletsa kulowa | "Alamu yotsika" yokhazikika ikhoza kusinthidwa kukhala "alamu yotsika" kudzera mu pulogalamu yosinthira |
| Mtundu wa zizindikiro | Mulingo woyezera wa thermocouple yofanana ndi -10 ~ 100mV. |
| Mulingo woyezera | Ogwiritsa ntchito amapanga makonzedwe awoawo akamayitanitsa, ndipo amawasonyeza pamzere wakumbuyo kapena kwina kulikonse. |
| Kubwezera kozizira komwe kwamangidwa mkati | ±1°C(Malipiro -20°C~ +60°C) |
| Zotsatira: | |
| Chizindikiro chotulutsa | Chizindikiro cha DC (chamakono/voteji) |
| Kukaniza Katundu | Kukana kwa katundu wamakono ≤500Ω (kosinthika) Kukana kwa voteji |
| Mphamvu yoperekera | 20-35VDC |
| Kugwiritsa ntchito mphamvu | Mphamvu yotulutsa magetsi |
| Chizindikiro cha LED | Chobiriwira: Alamu yowonetsa mphamvu ya L1 yowala pang'ono, alamu yowala kwambiri ya L2 yowala |
| Kulondola kwa zotsatira | Chonde onani "Input Signal Type and Range Table" kuti mudziwe zambiri |
| Nthawi yoyankha | Kufikira 90% ya mtengo womaliza mkati mwa 300ms |
| Kutentha kumasinthasintha | 0.005%FS/℃ |
| Magawo a kutentha | Kutentha kogwira ntchito: -20℃~+60℃, kutentha kosungirako:-40℃~+80℃ |
| Chinyezi chocheperako | 10% ~ 95% RH palibe kuzizira |
| Mphamvu yotetezera kutentha | ≥2000VAC/mphindi (pakati pa input/output/power supply) |
| Kukana kutchinjiriza | 100MΩ (500V DC) (pakati pa input/output/power supply) |
| Kugwirizana kwa maginito amagetsi | GB/T 18268, IEC 61326-1 |
| MTBF | 80000h |
| Zofunikira pa waya | Gawo lopingasa ≥ 0.5mm²; Mphamvu yotetezera kutentha ≥ 500V |
| Zipangizo zogwirira ntchito kumunda | Masensa a K. S, E, J, B, T, R, N TC |
Chidziwitso: Ntchito ya njanji yamagetsi ndi ntchito yosankha, ndipo ogwiritsa ntchito ayenera kufotokoza
njira yopezera magetsi poyitanitsa
Kusankha kwa zolumikizira za njanji yamagetsi kungatanthauze tsamba 89 la "Annex"
Mwachitsanzo: zolowetsa ziwiri ndi zotulutsa ziwiri, zolowetsa ziwiri za thermocouple K (-200-1370C),
magetsi awiri a 4-20mA, magetsi a 24V, chitsanzo: PHG-22TT-1111
