Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference as well as calculations to handle any non-linearities. For a long time, we’ve suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we’re happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple and even give you notification when the temperature goes out of range or a fault occurs. Very fancy!

This converter communicates over 4-wire SPI and can interface with any KJ, NRSTE, or B-type thermocouple.

This breakout does everything for you and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator,, and level-shifting circuitry, all assembled and tested. It comes with a 2-pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perf board). We even added inline resistors and a filter capacitor on board for better stability, as recommended by Maxim. It goes great with our 1m K-type thermocouple or any other thermocouple!

Features and Specifications:

  1. Works with any KJ, NRSTE, or B-type thermocouple
  2. -210°C to +1800°C output in 0.0078125° resolution; note that many thermocouples have about ±2°C to ±6°C accuracy or worse depending on the temperature and type, so the resolution will be a lot better than the accuracy!
  3. Internal temperature reading
  4. 3.3 to 5v power supply and logic level compliant!
  5. SPI data requires any 4 digital I/O pins
