MAX31865 RTD Platinumความต้านทานอุณหภูมิเครื่องตรวจจับโมดูลPT100 To PT1000

Features and benefits

1. Support 100Q to 1kQ (*C) platinum resistance RTD (PT100 to PT1000);

2. Compatible with 2-wire, 3-wire and 4-wire sensor connections;

3. SPI compatible interface;

4.15-bit ADC resolution with a nominal temperature resolution of 0.03125 ㆍC(variable with RTD nonlinearity);

5. The total accuracy is maintained at 0.5 ㆍC (0.05% of full scale) under the entireworking conditions;

6 fully differential VREF input;

7. Conversion time: 21ms (maximum);

8. Integrated fault detection to increase system stability: (RTD open circuit, RTD shortcircuit to voltage outside the range or short circuit of RTD components).

Please note: this does not include an RTD sensor!
