Temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensor is the core part of temperature measuring instruments and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the sensor material and electronic component characteristics, it can be divided into two categories: thermal resistor and thermocouple.

Soluție de circuit de achiziție a temperaturii 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 ℃. în plus, the temperature measurement ranges of Pt500, Pt1000, etc. sunt reduse succesiv. Pt1000, temperature measurement range -200～420 ℃. Conform standardului internațional IEC751, caracteristicile de temperatură ale rezistenței de platină Pt1000 îndeplinesc următoarele cerințe:
