- The MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire RTDs for better accuracy. Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC. - 15-bit ADC resolution with a nominal temperature resolution of 0.03125 derajat C (variable with RTD nonlinearity).
Specifications: Supports PT100¸ to PT1000¸ Conversion time: 21ms (maximum) The total accuracy is maintained at 0.5 Derajat C (0.05% of full scale) under the entire working conditions SPI compatible interface, compatible with 2-wire, 3-wire and 4-wire sensor connections Each order comes with one assembled RTD amplifier breakout board. Also comes with two 2-pin terminal blocks (for connecting to the RTD sensor) and pin header (to plug into any breadboard or perfboard). A required PT100 RTD is not included!
