he VEGA VEGABAR 52 is a Pressure Transmitter for the measurement of gauge pressure and absolute pressure. Products to be measured are gases, vapours and liquids. The sensor element in the VEGABAR 52 is a CERTEC® measuring cell with a rugged ceramic diaphragm. The process pressure causes a capacitance change within the measuring cell. This change is converted into an appropiate output signal and is outputted as measured value.
