Specification sheet VEGABAR 28 Two-wire 4 ... 20 mA Pressure sensor with ceramic measuring cell Application area The VEGABAR 28 is a universally applicable pressure sensor with switching function and ceramic measuring cell. It is used for measuring gases, vapours and liquids. Even with high requirements for robustness and hygiene, the device records the measured values with high accuracy. The optional universal connection for hygiene adapters reduces the installation effort and stockkeeping. Your benefit · High plant availability through maximum overload and vacuum resist- ance of the ceramic measuring cell · Coloured 360° switching status display · Convenient wireless setup and diagnostics with smartphone via Bluetooth · Easy integration into control systems due to a variety of connection technologies Function The heart of the pressure transmitter is the pressure measuring cell transforming the pressure into an electrical signal. This pressuredependent signal is convereted by the integrated electronics into a standardized output signal. Sensor element with VEGABAR 28 is the ceramic CERTEC® measuring cell with excellent long-term stability and high overload resistance.
