Features Convenient Conversion: The K type thermocouple module can convert ambient temperature into temperature compensation voltage through internal temperature detection diode. Long Service Life: The K type thermocouple probe has simple structure, anti-interference, small error and long service life. K-type thermocouple temperature probe sensor has enough quantity and length to meet your daily needs. Multifunction: The K type thermocouple probe has 12 bit analog / digital thermocouple converter, cold end compensation sensing and calibration, digital controller, 1 SPI compatible interface and 1 related logic control. High accuracy: The T and t inputs are connected to the low noise amplifier A1 to ensure the high accuracy of the detection input, while isolating the thermocouple connection wire from the interference source. Signal Conditioning Amplifier: there is a signal conditioning amplifier inside the K-type thermocouple module, which can convert the thermocouple signal into a voltage compatible with the ADC input channel.
