{"title":"PT100 Platinum RTD Temperature Sensor","handle":"platinum-rtd-sensor-pt100","url":"/products/platinum-rtd-sensor-pt100","description":"This PT100 is a platinum RTD (Resistance Temperature Detector) for accurate temperature sensing. It has a nominal resistance of 100Ω at 0°C, with resistance changing as temperature changes.It is suitable for applications across a broad temperature range, and is commonly used where stable, repeatable temperature measurement is needed. The sensor uses a three-wire connection scheme, with the two red wires connected to one end of the resistor and the white wire connected to the other.For use with the SparkFun Qwiic PT100 ADC, connect the red wires to terminals 3 and 4, connect the white wire to terminal 2, and short the A and B pads on the back of the Qwiic PT100 PCB. Use Example4-3-Wire from within the ADS122C04 library.When checking the wiring with a DMM, you should see approximately 1Ω between the red wires and approximately 100Ω between a red wire and the white wire.Specifications:Nominal resistance at 0°C: 100ΩTemperature Coefficient (0°C up to 100°C): 3.85 - 10-3 K-1Tolerance classes to DIN EN 60751: A, BOperating Temperature Range: -50°C up to 550°CMeasurement Current (DC) at 25°C: 1mAMaximal Permissible Peak Current (DC) at 25°C: 3mAInsulation Resistance: > 10MΩSelf-heating at 0°C: < 0.5 K / mWA useful sensor for temperature logging, process monitoring, lab projects, and Qwiic PT100 ADC builds.","vendor":"SparkFun","product_type":"Temperature Sensor","in_stock":true,"options":[],"variants":[{"id":15997,"title":"Default Title","sku":"SF-SEN-17059","mpn":"SEN-17059","price":30.35,"on_sale":false,"in_stock":true,"available_quantity":43}]}
