 Process Analysis – OPTISENS ODO 2000
 
Optical dissolved oxygen sensor for waste water analysis
 
Optical dissolved oxygen sensors are widely used to control and monitor oxygen concentration during the biological treatment of sewage water.
 
The dissolved oxygen sensor OPTISENS ODO 2000 from KROHNE has a standardized robust design and a long lifespan. Therefore the sensor is especially designed for small and medium-sized wastewater treatment plants, where regular calibration and cleaning of the sensors is difficult due to limited maintenance resources.
 
OPTISENS ODO 2000's use of the optical principal interacting with a fluorescent membrane means there's no need for recalibration. Precision and reliability remain constant. The integrated spray cleaning system minimizes the need for manual cleaning, which means longer intervals between maintenance.
 
Highlights
 
  • No recalibration necessary
  • Reliable measurement via fluorescence measurement
  • Fast response time in all application
  • No media flow required
  • Long-term stability due to reduced clogging by integrated spray cleaning system
  • Low cost of ownership
  • Suitable for installation with telescopic rod SENSOFIT IMM 2000

Industries
  • Waste water industry

Applications
  • Monitoring the oxygen content in mg/l in aeration basins
  • Controlling biological treatment in aeration basins, which can also be combined with measuring nitrate and ammonium

 Process Analysis – OPTISENS ADO 2000
 
Digital dissolved oxygen sensor for waste water applications
  • Digital sensor of the OPTISENS 2000 series for use in waste water applications
  • Robust stainless steel body and automatic spray cleaning
  • Low maintenance costs with long service intervals

As all the sensors of the OPTISENS 2000 sensor series, the ADO 2000 dissolved oxygen sensor is equipped with digital communication, a stainless steel enclosure, integrated spray cleaning and the mounting option on an extendable telescopic rod. These unique features enable the ADO 2000 sensors for use in municipal and industrial waste water treatment facilities.
 
The "Clark" electrode used in the ADO 2000 has a patented design, which guarantees reliable, precise measurements of the concentration of dissolved oxygen in water along with excellent long-term stability. Combined with the low maintenance costs, this allows extremely costeffective operation of the OPTISENS 2000.
 
Highlights
  • Robust stainless steel enclosure
  • Automatic spray cleaning
  • Mounting option on a flexible telescopic rod
  • "Clark" electrode with patented design and Teflon membrane for long lifespans
  • Not affected by optical effects (i.e. air bubbles)
  • Easily replaceable electrode cartridge
  • Wide measuring range: 0...20 mg/l DO
  • Automatic temperature compensation
  • Easy to calibrate
  • Digital communication with the converter
  • Up to four OPTISENS 2000 sensors can be connected to one MAC 080
  • Automatic sensor detection during installation

Industries
  • Municipal and industrial waste water treatment facilities
  • Water monitoring stations

Applications
  • Monitoring and control of water treatment processes
  • Continuous monitoring of the oxygen concentration in aeration basins
  • Monitoring of the water quality of waste water treatment facilities or final effluents
