PT100/PT1000 решение за верига за събиране на температура

Metal thermal resistors such as nickel, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platinum has the most stable physical and chemical properties and is the most widely used. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. Освен това, the temperature measurement ranges of Pt500, Pt1000, и т.н. are successively reduced. Pt1000, temperature measurement range -200～420 ℃. According to the IEC751 international standard, the temperature characteristics of the platinum resistor Pt1000 meet the following requirements:
