The Thermocouple Amplifier/Converter is a versatile and easy-to-use solution for interfacing with a wide range of thermocouples. Unlike traditional thermocouple amplifiers that are limited to K-type thermocouples, this breakout board can handle K, J, N, R, S, T, E, and B type thermocouples, providing flexibility for different temperature sensing applications.

This high-quality converter simplifies thermocouple integration by offering 4-wire SPI communication, making it easy to connect to any microcontroller, even those without analog inputs. It provides precise temperature readings from -210°C to +1800°C with a 0.0078125° resolution, though note that the accuracy of the thermocouple itself may vary depending on the type and temperature. The board also includes features like cold-junction compensation and fault detection to notify you if the temperature goes out of range or if there's an issue with the thermocouple.

Key Features:

  • Supports various thermocouple types: Works with K, J, N, R, S, T, E, and B thermocouples.
  • Wide temperature range: Measures temperatures from -210°C to +1800°C.
  • High resolution: 0.0078125° resolution, though actual accuracy may vary based on the thermocouple used.
  • Cold-junction compensation: Ensures accurate readings by compensating for the temperature of the junction.
  • Fault detection: Alerts when the temperature goes out of range or if a fault occurs.
  • SPI interface: Easily connects to microcontrollers with SPI data communication, requiring only 4 digital I/O pins.
  • Built-in components: Includes a 3.3V regulator, level shifting circuitry, inline resistors, and a filter capacitor for better stability.

This breakout board comes fully assembled and tested, with a 2-pin terminal block for thermocouple connection and a pin header for easy breadboard integration. It's compatible with 3.3V to 5V power supplies, ensuring it can be used in a variety of projects. However, thermocouples are not included, so you'll need to purchase one separately.

Additional Info:

  • Dimensions: 25.0mm x 22.0mm x 3.0mm (1.0" x 0.9" x 0.1")
  • Weight: 3.5g (0.1oz)

This thermocouple amplifier/converter is a reliable, easy-to-use solution for temperature sensing, perfect for projects that require precise, long-range temperature measurements.
