MAX6675 K-type Thermocouple Sensor Module

Thermocouple module temperature sensor K - type thermocouple module

The MAX6675 is a complex monolithic thermocouple digital converter with a signal conditioning amplifier, a 12-bit analog / digital thermocouple converter, a cold-side compensation sensor, and

Correction, digital controller, an SPI compatible interface and a related logic control.

The MAX6675 has a signal conditioning amplifier that converts the thermocouple signal into a voltage compatible with the ADC input channel, and the T and T- inputs are connected to the low noise amplifier A1 to

The test detects the high accuracy of the input while isolating the thermocouple connecting wires from the source of the interference. The thermocouple output thermocouple is amplified by the low noise amplifier A1, followed by the A2 voltage

After being buffered, it is sent to the input of the ADC. Before converting the temperature voltage value to the equivalent temperature value, it is necessary to compensate the cold junction temperature of the thermocouple.

The difference between the temperature around the MAX6675 and the actual reference value at 0 ° C.

Thermocouple function is to detect the difference between hot and cold temperature, thermocouple thermal node temperature can be 0 ℃ -1023.75 ℃ range. The cold end is the circuit board for the MAX6675

Ambient temperature, which varies in the range of 20 ° C to 85 ° C. When the cold junction temperature fluctuations, MAX6675 can still accurately detect the hot side of the temperature changes. The MAX6675 is supplied via a cold end

Compensation and correction of ambient temperature changes, the device can be the ambient temperature through the internal temperature detection diode into a temperature compensation voltage, in order to produce the actual thermocouple temperature

The measured value of the MAX6675 is measured from the output of the thermocouple and the output of the sense diode. The device's internal circuitry sends the diode voltage and thermocouple voltage to the ADC.
