The Dr. Födisch MGA 12 is a cold gas measuring system for continuous emission measurement of pollutants in flue gas and for process control. In the MGA 12 four independent, selectively working measuring methods apply: infrared absorption (NDIR), electrochemical cell and paramagnetic measuring method as well as thermal conductivity sensor.

The Dr. Födisch MGA 12 Ex is a cold gas measuring system for continuous emission measurement of pollutants in potentially explosive atmospheres.

MGA 12

  • Simultaneous measurement of up to eight gas components with limit value signalling and measuring range change-over
  • Two separated gas paths possible
  • Local diagnosis of the system state
  • Display of bar diagram for every component
  • Flow control as well as display of flow rate
  • Reduced cross-sensitivities by internal spectral filter
  • Internal monitoring for condensate ingress with switch contact for pump switch-off
  • Control of a back-purging probe (interval and pulse time)
  • Control of zero point drift
  • Low maintenance requirement

MGA 12 Ex

  • Protective principle Ex d
  • Pressure-resistant gas path up to 3 bar
  • Explosive gases can be passed through in a closed loop
  • Simultaneous measurement of up to five gas components
  • Reduced cross-sensitivities through internal spectral filter
  • Integrated zero gas valve for zero point correction
  • All gas-contacting elements are made of metal
