Abstract: This paper presented a signal conditioning circuit for platinum resistance type temperature sensors. The circuit has a measurement accuracy of 005% and maintains high precision operation in harsh environments. At the same time, the circuit has a simple structure, and the compatibility of the PT100 and PT1000 sensors can be realized by simply changing the bridge arm resistance and the amplification factor configuration resistor.
Key words: RTD； conditioning circuit； filter
