Function
•
The device serves for continuous measurement of gas concentrations in industrial
plants
• The device is an in-situ measuring system which means measuring is done directly
in the gas carrying duct
• Measuring components: SO
reference variables temperature and pressure
• Measuring principle: Differential Optical Absorption Spectroscopy (DOAS)
• To maintain measuring reliability, a permanent air flow (optics purge air) protects
and keeps the optics free from soot and dust particles as well as condensate and
moisture condensation
• Ignition protection type "pressurized enclosure" is applicable when using the
GM32 Ex in potentially explosive atmospheres. All relevant enclosures of the
sender/receiver unit and connection unit connected together via a pressure-proof
metal hose are purged with a protective gas. The protective gas can be air suc‐
tioned in from the non-potentially explosive atmosphere or an inert gas.
