.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.

1)

T

he actual sensor element is the CERTEC

®

measuring cell with

rugged ceramic diaphragm. The hydrostatic pressure causes a
capacitance change in the measuring cell via the ceramic diaphragm.
T

his change is converted into an appropriate output signal.

1)

F

or use in closed vessels under vacuum, the instrument is available with

absolute pressure measuring ranges.
