.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.
