    Description

    Pressure transmitter with chemical seal

    Application area

    Liquids and gases at high temperatures

    The VEGABAR 81 is a pressure transmitter with chemical seal for pressure and level measurement. The chemical seal systems of VEGABAR 81 adapted to the process, ensure a reliable measurement even with highly corrosive and hot products. The simple connection of VEGABAR series 80 sensors as electronic differential pressure opens new possibilities for the measurement of differential pressures.

    Your benefit

    • Simple adaptation thanks to verious configuration options
    • Reliable measurement with temperatures up to 400 °C
    • Reliable measurement independent of foam generation or tank installations

    Pressure transmitter with chemical seal for hot and chemically aggressive media

    The pressure transmitter VEGABAR 81 with chemical seal system demonstrates its capability especially in high temperatures and aggressive media. A wide range of diaphragm materials and coatings make this pressure transmitter an essential instrument across many sectors, particularly in  the chemical and petrochemical industries. 
    The pressure transmitter with chemical seal delivers reliable measurement data for feedback control systems or protective equipment, e.g. for

    • continuous monitoring of process pressure in reactors 
    • exhaust pressure of flue gas, e.g. in waste incineration 
    • pipeline pressure in dairies 
    • steam pressure control in steam drums 
    • pressure monitoring in LNG tanks
