| Abstract: | For application of PT100 in industrial temperature measurement, the transfer function method based nonlinear correction is proposed and its superiority and practicality is verified. Multi point temperature program is designed based on three wire PT100, using C8051F410 processor as the core, using the on chip ADC time shared control, and multi channel temperature acquisition is realized. Practice showed that this scheme can increase the temperature measurement accuracy and efficiency of system development, and can be widely used in industrial control field. |
