The VEGABAR 86 is a submersible pressure transmitter for level
measurement in wells, basins and open vessels. Its great flexibility
through different cable and tube versions allows the instrument to be
used in many different applications.
Measured products are liquids.
Depending on the instrument version and measurement setup, meas-
ured products can also be viscous or contain abrasive substances.
The sensor element is the CERTEC
ceramic diaphragm. The process pressure deflects the ceramic
diaphragm and causes a capacitance change in the measuring cell.
This capacitance change is converted into an electrical signal and
outputted as measured value via the output signal.
The measuring cell is available in two sizes:
•
CERTEC (ø 28 mm) with sensor 32 mm
®
•
Mini-CERTEC (ø 17.5 mm) with sensor 22 mm
®
A temperature sensor in the ceramic diaphragm of the CERTEC
on the ceramic base of the Mini-CERTEC
actual process temperature. The temperature value is output via:
•
The display and adjustment module
•
The current output or the additional current output
•
The digital signal output
