MAX31865 PT100/PT1000 RTD 3.3/5V Temperature Thermocouple Sensor Amplifier Board
- Easy-to-Use: MAX31865 is thermistor to digital output converter optimized for platinum resistance temperature detectors (RTDS).
- RTD Resistance to Digital Output: The external resistor sets the RTD sensitivity, and the high precision Delta-σ ADC converts the ratio of the RTD resistance to the reference resistance into a digital output.
- Safety and Protection: The MAX31865 input has overvoltage protection up to 45V and provides configurable RTD and cable open and short condition detection.
- PT100 Probe: PT100 probe line 0.5M PTFE line on -50~200°C with accuracy 0.5%.
