VEGABAR 17

Process pressure transmitter with metal sensor

Application area
VEGABAR 17 is a pressure transmitter for measurement of gauge pressure and absolute pressure. Measured products are gases, vapours and liquids. The front flush versions are also suitable for use in viscous or contaminated products.

Advantages
Small, compact dimensions
Stainless steel housing with clamp connection or cable outlet
Zero and span adjustable
Deviation < 0.5 %
Wetted parts of stainless steel

Function
The process pressure causes a resistance change in the sensor element via the stainless steel diaphragm. This change is converted into an appropriate output signal and outputted as measured value. With measuring ranges up to 16 bar, a piezoresistive sensor element with internal transmission liquid is used. From 25 bar, a strain gauge sensor element is used on the rear of the stainless steel diphragm. This dry system operates without additional isolating liquid.
