Level measurement of sludge, highly viscous liquids and liquids with suspended solids.
Having no moving parts, the sensor offers stable measurement even with sticky liquids or liquids with suspended solids.
Long service life even with corrosive liquids due to air preventing corrosive gases from penetrating into the controller.
Sensor requires no electricity, so can be used in hazardous areas with the controller installed in a safe area.
Principle of operation
Controller sends air to the sensor placed in the tank, and measures the back pressure, continuously indicating a level and giving a 4 to 20mA DC output.
