Tying up
Immersion and swinging dissolved-oxygen cell with a DANFOSS sensor
Length: 50-300cm (optional)
with Pt100 temperature sensor
10m measuring-cabel.
Danfoss sensor
Fixing according to local demand
Flow-through dissolved-oxygen cell with a DANFOSS sensor
Water must be free-bleeding because dissolved-oxygen content of water is pressure-dependent.
Sensor must always be placed in the water.
Influent water should be turnable off in order to cleansing.
63mm “T” unit
Female pipe optional size: G3/4″ or G2″
