DO30G 용존산소 센서

용존산소용 DO30G 센서는 하수처리장, 유출활성 슬러지 공정 및 음용수 처리와 같은 수처리 설비에서 사용하도록 설계되었습니다. 또한 하천 감시, 섭취 보호, 양식장 및 수질이 중요한 분야에도 효과적입니다. 

이 갈바닉셀은 반응 시간이 빠르고 장기적으로 안정성이 우수하며 교체 가능한 다이아프램과 케이블 사용으로 유지보수가 용이합니다. 온도 보상을 위해 온도 센서가 내장되어 있습니다. DO30G 센서는 플로팅 볼 피팅 또는 침적형 피팅에 사용할 수 있습니다. 


  • 빠른 응답 시간
  • 장기간 안정성이 우수함
  • 쉬운 멤브레인 교체

PB30/PB350G/PB360G Floating Ball

The floating ball holder for the DO30 features a design which minimizes fouling by the process. A brass ring around the sensor facilitates a check for membrane integrity, and helps to eliminate any deposits of algae, making a cleaning system unnecessary for the model PB30. Maintenance is very simple, with only periodic inspection and calibration needed.


  • Easy to install
  • Easy calibration
  • Sensor diagnosis for membrane integrity

FD30/PH8HG/DOX8HS Immersion Adapter

The immersion fitting is designed for installing the DO30G sensor in tanks, open vessels and drains. It can be supplied in lengths between 0.5 and 2.0 meter. Flange mounting is also possible. In applications with a heavy load of solids the use of a cleaning system is recommended, so an option, a "jet cleaner" is available for the immersion fitting. The use of this device can extend the continuous measurement period and eases maintenance.


  • Various immersion depths
  • Flange mounting possible
  • Cleaner option
  • Sensor diagnosis for membrane integrity

The control of the world's water resource is arguably one of the most important issues. Water demand from industry and domestic users is set to rise throughout the industrialized world. Yokogawa has been applying minimized maintenance measurement systems.


In a batch tank, analyzers such as dissolved oxygen (DO) analyzers, oxidation-reduction potential (ORP) meters, and mixed liquor suspended solid (MLSS) analyzers are used. To reduce the maintenance frequency, measures must be taken to prevent dirt accumulation on the sensor. As the liquid level in a tank can vary greatly, great care should be taken when selecting the sensor installation position in a tank.
