VEGABAR 39 • Three-wire 1 x transistor or 4 … 20 mA

57536-EN-200831

• 

Process pressure

Level

Fig. 3: Process pressure measurement VEGABAR 39

The process pressure acts on the sensor element via the process dia-

phragm. The process pressure causes a resistance change which is 

converted into a corresponding output signal and output as measured 

value.

Piezoresistive sensor element

Measuring ranges up to 100 bar: piezoresistive sensor element with 

internal transmission liquid is used.

Strain gauge (DMS) sensor element

For measuring ranges above 250 bar, a strain gauge (DMS) sensor 

element (dry system) is used.
