Abstract

본 발명은 작동유 온도 변화에 따른 보상 압력을 이용한 하물 중량 측정 장치 및 방법에 관한 것이다. 이를 위해 본 발명의 하물 중량 측정 장치는 리프트 실린더와, 상기 리프트 실린더 라인에 장착되고, 상기 리프트 실린더 내부 압력을 측정하는 압력센서와, 상기 리프트 실린더 내부에 장착되고, 상기 리프트 실린더의 작동유 온도를 감지하는 온도센서와, 상기 온도센서를 통해 감지된 작동유 온도 변화에 따라 미리 설정된 압력 보상값만큼 무 부하 시 압력 값과 최대 부하 시 압력값을 보상하여 변경 설정하고, 변경 설정된 압력값들을 이용하여 하물의 중량을 측정하는 제어부를 포함하는 것을 특징으로 한다.
