Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long
PT1000 platinum RTD probe on a 1 m three-wire cable, 1000 Ω at 0°C. Requires a dedicated amplifier (e.g. MAX31865) to convert resistance to temperature; not directly readable by a standard ADC.
Pinout
- RTD lead A
One side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.
Type · Unknown - RTD lead B
Other side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.
Type · Unknown - 3-wire compensation lead
Third RTD wire connected to one end of the PT1000 for 3-wire RTD amplifier lead-resistance compensation. Leave disconnected for 2-wire amplifiers per Adafruit.
