Principle

The digital K-type high-temperature sensor consists of a signal amplification and conversion module and an armored K-type thermocouple probe. When the K-type thermocouple probe is placed in a high-temperature heat source, a small voltage proportional to the temperature is generated between its two ends due to the thermoelectric effect. The signal amplification and conversion module, equipped with the CT1780 specialized chip, amplifies this weak voltage signal, performs analog-to-digital conversion and compensation, and finally transmits the measured temperature of the probe to the main controller via the Gravity One Wire interface.
