Q: What is the difference between PT100 and PT1000?Answer: The PT100 reference resistor is 402R and the PT1000 reference resistor is 4.02K.Q: What is the temperature measurement range:A: The measurement range is -200-550 degrees Celsius. (See MAX31865 Specification Page 21)MAX31865 AFEHigh precision 0.1%/25ppm 402R reference resistorStandard SPI interface, support SPI daisy chain for multi-channel temperature acquisition.Support PT100/PT1000 two-wire, three-wire, four-wire mode, the default is 4-wire connection.1. Two-wire connection mode: Short-circuit A and B in the left picture and short-circuit on the right side of jumper C (factory default short-circuit on the right side).2, three-wire connection: A short, B disconnect, C short on the left, disconnected on the right.3. Four-wire connection mode: A disconnection, B disconnection, short-circuiting on the right side of C, and disconnection on the left side.4. D is the reference resistance and the resistance is 402R.5, the factory default is the four-wire sensor connection.
