Deltabar PMD75 차압계는 압저항 원리 센서와 금속 멤브레인으로 구성됐으며 모든 산업 분야에서 액체, 증기 및 가스의 연속 압력 측정이 가능합니다. 3개의 키로 간편하게 시운전 및 작동이 가능합니다. 통합된 HistoROM 데이터 모듈을 통해 프로세스 및 장치 매개 변수를 쉽게 관리 할 수 있습니다. SIL2 / 3 안전 어플리케이션에 사용하기 위해 IEC 61508에 따라 설계되었습니다.
차압 모니터링을 통해 액체의 레벨, 부피 또는 질량이 측정 가능하며 가스, 증기 및 액체의 유량 측정 또한 가능합니다.
프로세스 커넥션: 쓰레드

국제 방폭 인증서, 오버필 방지 WHG, SIL, 선급 인증서
장점
최고의 정확성, 재현성 및 장기 안정성
SIL2 / 3적용 가능하며 gas tight feedthrough로 인한 최고의 안전성과 IEC 61508인증을 보유함
현장 기기 디스플레이, 4-20mA HART, PROFIBUS PA, FOUNDATION Fieldbus를 통해 쉬운 시운전 가능
센서, 디스플레이 및 전자 파트를 쉽게 교체 가능하며 이로 인한 잠재 비용 감소
HistoROM 데이터 관리를 통해 빠르고 쉬운 시운전, 유지보수 및 기기 진단 가능
최대 420bar / 42MPa / 6300psi 측정 시 과부하 저항 및 기능 모니터링 가능
The Egyptian government is working to replace liquid fuels with natural gas. To achieve this they targeted increasing the number of CNG stations in their country from 306 to 1000 by the end of 2021.
