초음파 가스 누출 감지기 소개
초음파 가스 누출 감지기는 어쿠스틱 센서를 사용해 공정 환경에서 사람의 청각으로 감지할 수 없는 잡음 변동을 식별합니다. 센서와 전자기기는 가청 주파수(0 ~ 25KHz)를 제외한 초음파 주파수(25 ~ 100KHz)를 감지할 수 있습니다. 누적된 가스를 측정하는 기존의 가스 감지기와 달리 초음파 가스 감지기는 누출을 “듣고” 조기 경고 시스템을 트리거합니다.
The latest ultrasonic sensing technologies use a resonant sensor vs. traditional technology using a moving metal diaphragm (microphone). The active sensor element is a piezo-electric material (which converts mechanical deformation into electrical voltage) embedded in a ceramic medium. The sensors have an extremely high chemical resistance and a wide frequency range response band. The ultrasonic gas leak detector can be mounted in any orientation. Its sensor design has no moving parts so wear and tear is completely eliminated.
The Rosemount Incus Ultrasonic Gas Leak Detector is equipped with four of these piezo-electric sensors, covering a maximum range of 131.2 ft (40 m) radius from the detector. Each ultrasonic gas leak detector leaves the factory calibrated for life and will never expire. There is no zeroing or calibration required and no consumptive sensor elements to replace, ever.
Ultrasonic gas leak detection technology constantly monitors wide areas with advanced acoustic sensors specially tuned to process ultrasound emitted from pressurized gas leaks. Ultrasonic gas leak detectors don't wait until a hazardous gas concentration has accumulated or the gas cloud has made physical contact with a gas sensor. The response time is instantaneous for all gas types. Since ultrasonic gas leak detectors are immune to poisoning, they never require field calibration, and all intermittent sources of background ultrasound noises may be ignored by time delay settings.
