The DL 5000 Dissolved Oxygen probe is based on a unique equilibrium probe technology. This patented equilibrium probe technology is based on the partial pressure of oxygen rather than the diffusion rate of oxygen through the probe membrane.
The materials of construction combined with this unique design result in a no-internal-maintenance probe that is independent of process flow and fouling because the anode is not consumed. Bottom line an accurate, reliable, maintenance-free, Dissolved Oxygen measurement requiring less recalibration.
The Honeywell probe is housed in PVC casing. One end has a 1 NPT male thread for mounting. The sensor extends from the housing and is covered by a protective guard (of the same material as the casing) which allows sample entry while preventing physical damage.
The probe has permanent electrolyte which is sealed at the rear with an expansion chamber to compensate for pressure changes. The sensor assembly is permanently potted into the housing and is not field replaceable. Operational service in wastewater applications should consist of an occasional wash to remove any large deposits at the sensor end. This can usually be accomplished without removing the protective guard. If the protective guard is removed, additional care must be taken to minimize the chance of puncturing a hole in the probe membrane. See Probe Maintenance section for proper cleaning procedures.
Physically the probe consists of three electrodes and a thermistor for temperature measurement and compensation. Two electrodes are interspaced on a supporting substrate and covered with an electrolyte; these electrodes are connected as anode and cathode. The third or reference electrode is mounted in the center of the electrode support and is also in contact with the electrolyte. The anode and cathode perform the oxygen generation and reduction functions while the reference electrode maintains the correct electrochemical potential.
Typical ppb applications include power plant and semi-conductor applications for corrosion detection or dearator efficiency. Typical ppm applications include aeration, effluent, stream and aquaculture monitoring for compliance and control.
