VEGABAR 81 (Slave Sensor)

Description

The VEGABAR 81 slave sensor is combined with a sensor from the VEGABAR 80 series to produce an electronic differential pressure measurement. The unit is suitable for the measurement of differential pressure, level with superimposed pressure or vacuum, flow, density or interface. The chemical seal systems of VEGABAR 81 slave sensor adapted to the process ensure the measurement even with highly corrosive and hot products.

Application area

Reliable measurement of highly corrosive and hot media. Can be combined with any other sensor of VEGABAR Series 80 for electronic differential pressure measurement.

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
