Claims (3)
- 유량계(1)에서 검출된 유량펄신호와 온도차검출부(가)에서 검출된 온도차 검출신호를 적산표시부(나)에 입력시켜 적산량을 카운터(18)에 적산표시토록 하는 것에 있어서 온도차검출부(가)의 정전류원(5)와 고온측온도센서(6) 및 저온측온도쎈서(7)를 1조의 직열로 연결하되 정전류원(5)과 고온측온도쎈서(6) 사이의 접점은 저항(R1)을 통하여 증폭기(10)의 +입력단자에, 고온측온도센서(6)와 저온측온도센서(7)사이의 접점(D2)은 저항(R3)을 통하여 증폭기(9)의 +입력단자에 연결함과 동시에 저항(R2)의 귀환에 의한 증폭기(9)의 출력을 증폭기(10)의 -입력단자에 연결하여 온도차 측정회로를 구성한 적산식열량계.
- 제1항에 있어서 그온측 온도센서(RH)와 저온측온도쎈서(RL)의 각 양단접점을 차등폭기의 각 입력단자에 연결구성한 적산식열량계.
- 제1항에 있어서 정전류원(5) 회로를 정전류다이오드로 구성한 적산식 열량계.
