PT100 Platinum resistance thermometer

Product introduction： PT100 platinum resistance temperature sensors are suitable for temperature measurements between 20K and 500K. In this temperature range, platinum resistance temperature sensors have excellent repeatability and almost constant sensitivity. Platinum temperature sensors can also be used in magnetic and radiation environments within the tolerance range (1 degree). platinum temperature sensors have a common standard curve for environments above 70 K, which makes them very interchangeable in this environment. Oriental Chenjing provides thin-film platinum resistance on the basis of both smaller size, shorter response time and other characteristics, more extensive applications!
