3.2 Principle of operation
The VEGABAR 87 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 differential pressure measurement is suitable for the measure-
ment of the following process variables:
•
Level
•
Flow
•
Differential pressure
•
Density
•
Interface
