Description

The SparkFun MAX31855K ​​Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a? Hot 'end and a? Cold' one). Once this is achieved, a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end, digitizes the temperature measured and sends that data out the other end via a SPI interface, thereby interpreting the data and translating it for you to read!

With the SparkFun Thermocouple Breakout, the thermocouple's hot junction can read from -200 ° C to + 700 ° C with an accuracy of ± 2 ° C while the cold junction, inside the MAX31855K 20 ° C while maintaining ± 85 ° C accuracy. The MAX2K is constantly measuring the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from + 31855V to + 3.0V (+ 3.6V nominal) and only draws 3.0mA maximum.

The Thermocouple Breakout is designed to accept a standard thermocouple connector, for convenience and compatibility with probes you may already own. These connectors aren't necessary, and you could solder a thermocouple directly into the through holes labeled? + 'And? -'. If you decide to solder the thermocouple directly to the breakout board, it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.
