tion
The VEGABAR 86 slave sensor is combined with a sensor from the
VEGABAR 80 series for electronic differential pressure measurement.
The sensors are connected via a screened four-wire cable. The
measured value from the slave sensor is read in and factored into the
calculations. Parameter adjustment is carried out through the master
sensor.
The VEGABAR 86 is a suspension 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 be also viscous or contain abrasive substances.
Sensor element is the CERTEC ® measuring cell with robust ceramic
diaphragm. The process pressure deflects the ceramic diaphragm
and causes a capacitance change in the measuring cell. This capaci-
tance change is converted into an electrical signal and outputted as
measured value via the output signal.
The measuring cell design depends on the selected pressure type.
Relative pressure: the measuring cell is open to atmosphere. The
ambient pressure is detected in the measuring cell and compensated.
It thus has no influence on the measured value.
