Description

For precision temperature sensing, nothing beats a MAX31865 RTD Platinum Resistance Temperature Detector Module PT100-PT1000. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0 ºC, thus the name PT100.

Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100’s have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability. RoboticsBD

The MAX31865 is an easy-to-use thermistor-to-digital output converter optimized for platinum resistance temperature detectors (RTDs). The external resistor sets the RTD sensitivity, and the high precision Δ- Σ ADC converts the ratio of the RTD resistor to the reference resistor into a digital output. The MAX31865 has overvoltage protection up to ±45V and provides configurable RTD and cable open and short-circuit condition detection. Featured By RoboticsBD.
