Mai watsa zafin shigar RTD zai iya ware kuma ya canza siginar juriyar zafi (RTD) zuwa siginar DC, wanda ake amfani da shi don tuƙa nauyin. Tsarin hankali yana yiwuwa, kuma ana iya saita ainihin kewayon juriyar zafi ta hanyar software na kwamfuta. Yana da aikin ƙararrawa ta katsewa da aikin ƙararrawa na waje.
Wannan samfurin yana buƙatar a yi amfani da shi daban-daban, kuma an ware tashoshin samar da wutar lantarki, shigarwa da fitarwa.
| Shigarwa | |
| Siginar shigarwa | Siginar thermistor mai waya biyu ko uku (duba "Nau'in Siginar Shigarwa da Teburin Nisa" don ƙarin bayani) |
| Katsewar shigarwa | Ana iya canza "ƙarancin ƙararrawa" na asali zuwa "babban ƙararrawa" ta hanyar software na daidaitawa |
| Kewayen sigina | Tsarin aunawa mai dacewa na juriyar zafi |
| Kewayon aunawa | Masu amfani suna yin nasu tsarin lokacin yin oda, kuma suna nuna shi a lambar wutsiya ko akasin haka. |
| Wutar lantarki | 800μA |
| Fitarwa: | |
| Siginar fitarwa | Siginar DC (na yanzu/ƙarfin lantarki) |
| Iyakar kaya | Juriyar kaya ta yanzu ≤500Ω (wanda za'a iya keɓancewa) Juriyar nauyin wutar lantarki
|
| Sigogi na asali: | |
| Ƙarfin wutar lantarki | 20-35VDC |
| Amfani da wutar lantarki | Fitowar yanzu |
| Alamar LED | Kore: Alamar Wuta Ƙararrawa mai ƙarancin zango a kunne, hasken rawaya mai tsayi a kunne, hasken ja mai tsayi a kunne |
| Daidaiton fitarwa | Da fatan za a duba "Nau'in Siginar Shigarwa da Teburin Nisan" don ƙarin bayani |
| Lokacin amsawa | Isa ga kashi 90% na ƙimar ƙarshe a cikin 300ms |

| Danshin da ya dace | 10% ~ 95% RH babu danshi |
| Ƙarfin Dielectric | ≥2000VAC/min (tsakanin shigarwa/fitarwa/ samar da wutar lantarki) |
| Juriyar rufi | 100MΩ(500VDC) (tsakanin shigarwa/fitarwa/ samar da wutar lantarki) |
| Dacewar na'urar lantarki | GB/T 18268(IEC 61326-1) |
| MTBF | 800000h |
| Bukatun waya | Sashe na giciye ≥ 0.5mm²; Ƙarfin rufi ≥ 500V |
| Kayan aikin filin da suka dace | Ma'aikatan thermistors na waya guda biyu ko uku G53, Cu50, Pt100, Pt1000, Ni1000 |
Lura: 1. Aikin layin wutar lantarki aiki ne na zaɓi, kuma masu amfani suna buƙatar ƙayyade hanyar samar da wutar lantarki lokacin yin oda. Zaɓin haɗin layin wutar lantarki na iya komawa zuwa shafi na 89 na "Annex" 2. Lokacin shigar da RTD mai waya uku, ya zama dole a tabbatar cewa wayoyi uku suna da tsayi daidai gwargwado 3. Lokacin shigar da RTD mai waya biyu, dole ne a yi amfani da tashoshin shingen tsaro 5 da 6(2 da 3) a takaice.
