MAX31855K Thermocouple Amplifier Module

MAX31855 Thermocouple Amplifier Module converts the K, N, J, T or E Thermocouple signal into digital signal with cold-junction compensation.

It outputs 14-bit signed data through SPITM compatible interface in the read-only format. The temperature resolution is 0.25, the highest temperature readings is up to the + 1800℃ and the lowest temperature readings is to -270℃. And for K type thermocouple, the temperature range is -200℃ to +700℃, keep the accuracy of +/-2℃.

MAX31855 Thermocouple Amplifier Module is a thermocouple to digital output converter, built in 14-bit analog to digital converter (ADC). The Thermocouple module has cold end compensation detection and correction function, digital controller, SPI compatible interface, and associated control logic design. In the temperature controller, process control or monitoring system, it is designed to use with external micro controller (uC).

We have Various sizes of GPS-GSM Module. Check out our complete collection of ADC and DAC Modules.
