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 has the ability to give you a notification when the temperature goes out of range, or a fault occurs.? This converter communicates over 4-wire SPI and can interface with any K,J,N,R,S,T,E, 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. 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. Goes great with our 1m K-type thermocouple or any other thermocouple.
Features:
- Works with any K,J,N,R,S,T,E, or B-type thermocouple
- -210ºC to +1800ºC output in 0.0078125 resolution- note that many thermocouples have about to 2ºC, 6ºC accuracy or worse depending on the temperature and type, so the resolution will be a lot better than the accuracy!
- Internal temperature reading
- 3.3 to 5v power supply and logic level compliant!
- SPI data requires any 4 digital I/O pins
Note: this does not include a thermocouple Also, the terminal blocks included with your product may be blue or black.
