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.

PT100/PT1000 temperatuurregistratiecircuitoplossing

Metalen thermische weerstanden zoals nikkel, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platina heeft de meest stabiele fysische en chemische eigenschappen en is het meest gebruikt. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. In aanvulling, the temperature measurement ranges of Pt500, Pt1000, enz. zijn achtereenvolgens verminderd. Pt1000, temperature measurement range -200～420 ℃. Volgens de IEC751 International Standard, De temperatuurkarakteristieken van de platina -weerstand PT1000 voldoen aan de volgende vereisten:
