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.

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 ℃. Εξάλλου, the temperature measurement ranges of Pt500, 1000 Pt, και τα λοιπά. μειώνονται διαδοχικά. 1000 Pt, temperature measurement range -200~420 ℃. Σύμφωνα με το διεθνές πρότυπο IEC751, Τα χαρακτηριστικά θερμοκρασίας της αντίστασης Platinum Ptinum PT1000 πληρούν τις ακόλουθες απαιτήσεις:
