3.2 Principle of operation
The VEGABAR 51 is a pressure transmitter with chemical seal for
pressure measurement of highly corrosive and hot liquids.
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.
