Adafruit Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long

For precise temperature sensing, Platinum RTDs stand unparalleled. These resistance temperature detectors utilize a platinum resistor with a 1000-ohm resistance at 0°C, offering unmatched accuracy and stability. PT1000 sensors, more stable than typical thermistors, excel in laboratory and industrial applications.

This high-temperature PT100 sensor is crafted with a stainless steel shield, ensuring reliability from -50°C to 280°C. It uses the principle of resistance variation with a nominal function of 3.85Ω/°C. Ideal for processes requiring high precision, the PT1000 delivers superior performance over thermocouples and silicon-based sensors.

Each sensor includes three wires: two connect to the platinum resistor's sides, while the third, part of a 3-wire setup, aids in eliminating voltage drops when supported by an RTD amplifier. For seamless integration with microcontrollers, the Adafruit RTD sensor breakout is recommended.
