Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865

Per precisione temperatura sensing, nothing beats a Platinum RTD. 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 1000 ohm at 0°C, thus the name PT1000. Rispetto alla maggior parte dei termistori NTC/PTC, il tipo PT di RTD è molto stabile e preciso (but also more expensive) PT1000'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 statiful bility. Tuttavia, per ottenere quella precisione e precisione fuori dal tuo PT1000 RTD devi usare un amplificare che è progettato per leggere la bassa resistenza. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. Se stai cercando un grande sensore RTD RTD oggi, è il tuo fortunato giorno perché abbiamo un amorevole sensore di Adafruit RTD con il MAX31865 breakout per l'uso con qualsiasi 2, 3 o 4 fili PT1000 RTD!If you have a PT100 RTD, please visit this Pagina da acquistare a version of this board with the reference resistor for 100-ohm RTDsWe've carried various MAXIM thermocouple amplificers and they're great - but thermocouple don't have the best accuracy or precision, for when the readings must be as good as can be. The MAX31865 gestisce tutti i tuoi RTD needs, e può anche compensare 3 o 4 cavi RTDs per una migliore precisione. Connect to it with any microcontroller over SPI and read out 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 microcontroler.E
