For precise temperature sensing, no beats on Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that change resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is currently a small strip of platinum with a resistance of 1000 ohms at 0°C, so the name PT1000. Compared to most NTC/PTC thermistors, RTDs PT type is very stable and precise (but also more expensive) PT1000s have been used for many years to measure temperatures in laboratory and industrial processes and develop a reputation for safety (better than thermocouples). peatability, and stability. However, to achieve the accuracy and accuracy of your PT1000 RTD, you must use an amplifier designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If youre looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD sensor amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT1000 RTD. If you have a PT100 RTD, please visit this page to purchase a version of this board with the reference resistor for 100-Ohm RTDsWeve carried various MAXIM thermoelement amplifiers and great - but theyre but the thermoelements dont have the best accuracy or precision, when the readings must be as good as can be good as can be the MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire rTDs for better accuracy. Connect it to any microcontroller via SPI and read the resistance ratio from the internal ADC. We put a 4300 Ohm 0.1% resistor as a reference resistor on the breakout. We have some example code that will calculate the temperature based on the resistance for you. We even made the breakout 5V compliant, with a 3.3V regulator and level shifting, so you can use it with any Arduino or microcontroller. E
