Chotumizira kutentha cha RTD chimatha kupatula ndikusintha chizindikiro cha thermal resistor (RTD) kukhala chizindikiro cha DC, chomwe chimagwiritsidwa ntchito kuyendetsa katundu. Kapangidwe kanzeru ndikotheka, ndipo kuchuluka kwenikweni kwa kukana kutentha kumatha kukhazikitsidwa kudzera mu mapulogalamu apakompyuta. Ili ndi ntchito ya alamu yolumikizira ndi ntchito ya alamu yosakhala patali.
Chogulitsachi chikufunika kuyendetsedwa pachokha, ndipo magetsi, malo olowera ndi otulutsira magetsi amachotsedwa.
| Lowetsani | |
| Chizindikiro cholowera | Zizindikiro ziwiri za waya kapena zitatu za waya (onani "Mtundu wa Chizindikiro Cholowera ndi Tebulo Lozungulira" kuti mudziwe zambiri) |
| Kuletsa kulowa | "Alamu yotsika" yokhazikika ikhoza kusinthidwa kukhala "alamu yotsika" kudzera mu pulogalamu yosinthira |
| Mtundu wa zizindikiro | Kuyeza kofanana kwa kutentha |
| Mulingo woyezera | Ogwiritsa ntchito amapanga makonzedwe awoawo akamayitanitsa, ndipo amawasonyeza pamzere wakumbuyo kapena kwina kulikonse. |
| Mphamvu yolimbikitsa | 800μA |
| Zotsatira: | |
| Chizindikiro chotulutsa | Chizindikiro cha DC (chamakono/voteji) |
| Kulemera kwa katundu | Kukana kwa katundu wamakono ≤500Ω (kosinthika) Kukana kwa voteji
|
| Magawo oyambira: | |
| Mphamvu yoperekera | 20-35VDC |
| Kugwiritsa ntchito mphamvu | Kutulutsa kwamagetsi |
| Chizindikiro cha LED | Chobiriwira: Chizindikiro cha mphamvu Alamu yamtundu wotsika kuwala kwachikasu koyatsidwa, alamu yamtundu wapamwamba kuwala kofiira koyatsidwa |
| 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 ya dielectric | ≥2000VAC/mphindi (pakati pa input/output/power supply) |
| Kukana kutchinjiriza | 100MΩ(500VDC)(pakati pa input/output/power supply) |
| Kugwirizana kwa maginito amagetsi | GB/T 18268(IEC 61326-1) |
| MTBF | 800000h |
| Zofunikira pa waya | Chigawo chopingasa ≥ 0.5mm²; Mphamvu yotetezera kutentha ≥ 500V |
| Zipangizo zogwirira ntchito kumunda | Ma thermistors awiri kapena atatu a waya G53, Cu50, Pt100, Pt1000, Ni1000 |
Chidziwitso: 1. Ntchito ya njanji yamagetsi ndi ntchito yosankha, ndipo ogwiritsa ntchito ayenera kufotokoza njira yoperekera magetsi akamayitanitsa. Kusankha zolumikizira njanji yamagetsi kungatanthauze tsamba 89 la "Annex" 2. Mukalowetsa waya watatu wa RTD, ndikofunikira kuonetsetsa kuti waya zitatuzo ndi zofanana kutalika momwe zingathere. 3. Mukalowetsa waya wawiri wa RTD, malo otetezera chitetezo 5 ndi 6 (2 ndi 3) ayenera kuchepetsedwa.
