This sensor module integrates a standard K-type thermocouple probe with a signal conditioning IC that provides cold junction compensation and digital conversion. The thermocouple itself consists of Chromel (Ni-Cr) and Alumel (Ni-Al) conductors, offering a wide temperature range and good resistance to oxidation, making it suitable for harsh industrial environments. The onboard circuitry linearizes the non-linear thermocouple output and provides a calibrated digital readout.
The module outputs temperature data via a 3-wire SPI serial interface, simplifying integration with microcontrollers and data acquisition systems. The integrated high-impedance differential inputs ensure accurate measurement of the small thermoelectric voltage (approximately 41 µV/°C). The embedded break detection circuit provides a fault alert if the thermocouple wire becomes disconnected, enhancing system safety and diagnostic capability.
