We put a 4300 Ohm 0,1% resistor as a reference resistor on the breakout. Sensore Temperatura Rtd PT100 RTD Temperature Sensor Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 Infrared Thermometers & Laser Thermometers Sensore Precisione Arduino 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! 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 Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC. 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. Tuttavia, per ottenere quella precisione e precisione fuori dal tuo PT1000 RTD devi usare un amplificare che è progettato per leggere la bassa resistenza. 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.
