حل دائرة اكتساب درجة الحرارة PT100/PT1000

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 ℃. In addition, the temperature measurement ranges of Pt500, Pt1000, إلخ. 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:
