Description
Claims (1)
- 하기식(1)과 식(2)로 게인(Gain)과 오프셋(Offset)을 구하고, 구해진 게인(Gain)과 오프셋(Offset)를 이용하여 식(3)으로 증폭에러를 보장할 보정기전력(AP)을 구하여 가변저항의 사용없이 증폭에러를 보정하는 것을 특징으로 하는 디지탈방식 열전쌍(Thermo Couple) 신호변환기 증폭에러 보정방법.Gain = 9P-.............................. (1)Offset = ViL+ VrL× Gain ............... (2)AP = VaI× Gain + Offset ................. (3)여기서 ViH는 높은점 온도에서 이상적인 기전력값ViL은 낮은점 온도에서 이상적인 기전력값VrH는 높은점 온도에서 증폭된 열전쌍의 기전력값VrL는 낮은점 온도에서 증폭된 열전쌍의 기전력값VaI는 증폭된 입력 기전력값이다
