3.2 Principle of operation
VEGAWELL 52 is used for level and gauge measurement in wells,
basins and vessels open to the atmosphere, particularly in the water/
waste water industry as well as in the shipbuilding industry.
The actual sensor element is the CERTEC
rugged ceramic diaphragm. The hydrostatic pressure causes a
capacitance change in the measuring cell via the ceramic diaphragm.
This change is converted into an appropriate output signal.
For use in closed vessels under vacuum, the instrument is available with
1)
absolute pressure measuring ranges.
