Capacitance Type Level
Indicator | |
Capacitence type level measurement
are based on the physical properties of a capacitor.
Capacitance of a capacitor formed by two parallel plate
electrods is
1. Directly proportional to area
"A" of the electrode. 2. Inversely proportional to
distance 'd' between the plates & 3. Directly
proportional to die-electric ' ' positioned in between
them.
C = A / d The probe of the level sensor forms an
electrical capacitor with the surrounding metal
container wall when the vessel empty; an inital
capacitance exists between the electrode level sensor
& the metal wall. When the sensor is covered with
liquid the value of this capacitor increases and the
capacitance change is measured and converted into an
output signal proportional to the capacitance change.
Depending on the application is requirement, a
part or fully insulated flexible or solid rod probe is
selected. The probe head contains the electric
capacitance and current transducer
The System consists of 2 units
* Indicator :- Mounted where Indication
is require. * Prob Unit . :- Mounted on top of the
tank. These are used for conductive and
non-conducative liquids.
Conducative
liquids:- Water, Effluent, Milk, Beer, Acids
and Alkalies etc. Non-Conductive Liquids :-
Edible Oil, Turbine Oil, Synthetic Oil, Kerosene,
Diesel etc. |
