Mai watsa zazzabi na shigarwar RTD zai iya ware kuma ya canza thermal
resistor (RTD) siginar zuwa siginar DC, wanda ake amfani da shi don fitar da kaya.
Tsarin hankali yana yiwuwa, kuma ainihin kewayon thermal
ana iya saita juriya ta hanyar software na kwamfuta. Yana da aikin
na ƙararrawar cire haɗin gwiwa da aikin ƙararrawa na waje.
Wannan samfurin yana buƙatar sarrafa kansa, da kuma samar da wutar lantarki,
shigar da tashoshi masu fitarwa sun keɓe.
| Shigarwa | |
| Siginar shigarwa | Waya biyu ko uku siginonin thermistor waya (duba "Nau'in Siginar Shigar da Teburin Range" don cikakkun bayanai) |
| Kashe haɗin shigarwa | Za'a iya canza tsohuwar "ƙananan ƙararrawa" zuwa "high ƙararrawa" ta hanyar software na daidaitawa |

Lura:
1. PHG-11TZ - * 1+ baya hada da fitarwa part 2
2. Aikin dogo na wutar lantarki aiki ne na zaɓi, kuma masu amfani suna buƙatar tantance hanyar samar da wutar lantarki lokacin yin oda.
Zaɓin na'urorin haɗin dogo na wutar lantarki na iya komawa shafi na 89 na "Annex"
3. Lokacin shigar da RTD na waya guda uku, wajibi ne a tabbatar da cewa wayoyi uku suna da tsayi daidai gwargwadon yiwuwar.
4. Lokacin shigar da RTD mai waya biyu, matakan tsaro 4 da 2 dole ne su kasance gajeriyar kewayawa.
