What is The Design of High-Precision Temperature Measurement Circuit with Time-Sharing Multiplexing about?

In the industrial field, multichannel temperature measurement of electrical equipment such as motors is needed. This paper proposes a measurement circuit based on timesharing multiplexing. The circuit includes a microcontroller, a RTD-to-digital converter chip and three analog switch chips. The microcontroller controls the analog switch chip to gate the external RTDs in turn, thus realizing the time-sharing multiplexing of the RTD-to-digital converter chip. The test results show that the circuit has the characteristics of high precision, low power consumption, small size and low cost, and almost no measurement error is introduced after the lead wire compensation mechanism is adopted.
