PT100 Platinum Resistance Temperature Sensor
The PT100 platinum resistance thermometer is an excellent choice for applications that require temperature measurement and control between 70K and 500K. In this temperature range, platinum resistance thermometers have good repeatability and almost constant sensitivity. Within the allowable error range (1 degree), platinum resistance thermometers can also be used in magnetic fields and radiation environments.
Platinum resistance thermometers above 70K have a common standard curve, which makes platinum resistance thermometers very interchangeable. The thin-film platinum resistors provided by Jinzhengmao have smaller size, shorter response time, and wider application occasions.
Features
