3.2 Principle of operation
VEGABAR 53 is a pressure transmitter for measurement of overpres-
sure, absolute pressure or vacuum. Measured products are gases,
vapours and liquids in measuring ranges up to 4000 bar (400 MPa);
with front-flush version also viscous liquids in measuring ranges up to
600 bar (60 MPa).
The process pressure acts on the sensor element via the stainless
steel diaphragm and an internal transmission liquid. This causes a
resistance change which is converted into a corresponding output
signal and outputted as a measured value. With measuring ranges
up to 16 bar a pieoresistive sensor element is used, with measuring
ranges from 25 bar a strain gauge (DMS) sensor element.
