디지털 압력 트랜스미터 (K-20)
(Digital display pressure transmitter)
◆ 개요(Description)
▶ Microprocessor를 내장한 고정도의 디지털 압력전송기
▶ 알루미늄 다이캐스팅 연결 Terminal은 소형사이즈로 설치공간이 협소한 Process에서도 설치 가능
▶ 견고함, 장시간 사용 및 유지
▶ 전면부의 버튼 키를 이용하여 손쉽게 다양한 기능을 조정
▶ Ceramic Pressure Cell (Piezoresistive Silicon) Sensing Element는 고정도와 다양한 압력 매체를 측정이 가능
▶Stainless Steel 316L로 하우징 구성
▶측정된 값은 현장에서 LED 4 digit로 표시되며, 전류신호로 장거리 전송이 가능
