Product Details

The MAX31856 evaluation system (EV system) provides the hardware and software necessary to evaluate the MAX31856 thermocouple-to-digital converter.

The EV system includes the MAX31856PMB1 peripheral module with a Pmod™-compatible connector for SPI communication. The system also includes the USB2PMB1 adapter board for communication with the software and a K-type thermocouple for temperature sensing. Other thermocouple types (J, N, R, S, T, E, and B) can be evaluated with a user-supplied thermocouple.

Applications

  • Industrial Equipment
  • Industrial Ovens, Furnaces, and Environmental Chambers
  • Temperature Controllers
