CJMCU-6675 MAX6675 熱電偶模塊 溫度傳感器 K型熱電偶模塊


CJMCU-MAX6675是一個複雜的單片熱電偶數字轉換器，內部具有信號調節放大器、12位的模擬/數字化熱電偶轉換器、冷端補償傳感和校正、數字控制器、1個SPI兼容接口和1個相關的邏輯控制。


CJMCU-MAX6675內部具有將熱電偶信號轉換為與ADC輸入通道兼容電壓的信號調節放大器，T和T-輸入端連接到低噪聲放大器A1，以保證檢測輸入的高精度，同時使熱電偶連接導線與干擾源隔離。熱電偶輸出的熱電勢經低噪聲放大器A1放大，再經過A2電壓跟隨器緩衝後，被送至ADC的輸入端。在將溫度電壓值轉換為相等價的溫度值之前，需要對熱電偶的冷端溫度進行補償，冷端溫度即MAX6675周圍溫度與0℃實際參考值之間的差值。


熱電偶的功能是檢測熱、冷兩端溫度的差值，熱電偶熱節點溫度可在0℃-1023.75℃範圍變化。冷端即安裝CJMCU-MAX6675的電路板周圍溫度，該溫度在20℃-85℃範圍內變化。當冷端溫度波動時，MAX6675仍能精確檢測熱端的溫度變化。 MAX6675是通過冷端補償檢測和校正周圍溫度變化的，該器件可將周圍溫度通過內部的溫度檢測二極管轉換為溫度補償電壓，為了產生實際熱電偶溫度測量值，MAX6675從熱電偶的輸出和檢測二極管的輸出測量電壓。該器件內部電路將二極管電壓和熱電偶電壓送到ADC .
