Page 7: Safety Instructions For Use In Explosion Hazard Areas Zone 2
1.3 Intended Use • Messkonzept GmbH does not assume any liability in case of improper handling of the measuring device. Improper handling can cause hazards due to malfunction of the measuring device. • The FTC-series of gas analyzers offer high-precision measurement and detection of non-corrosive, dust-, condensate-, aerosol and oil mist-free gases (unless the design of the equipment is explic- itly declared to be suitable for this purpose). - Page 8 Page 7 of 47 0.6mm). Due to the dense filling with the inert material, the volume that can be filled by a gas in the measuring device is reduced and segmented to such an extent that no explosive zone is created in the measuring device even if there is a leak in the measuring gas path.

Page 9: Principle Of Measurement
Page 8 of 47 Chapter 2 Principle of Measurement 2.1 Determining Concentrations via Thermal Conductivity Thermal Conductivity Detectors (TCD) have been used in the chemical industry since the 1920s as the first process gas analyzers for the quantitative composition of gas mixtures. Every gas has a unique heat conductivity that is governed by its molar mass and viscosity. - Page 10 Page 9 of 47 ˚ ˚ Gas Out Gas In Figure 2.1: Schematic drawing of thermal conductivity measurement. The sensor is comprised in the stainless-steel block which is kept at a constant temperature. The FTC320 contains a thermal conductivity sensor that analyzes the quantitative composition of gas mixtures.

Page 11 of 47 For flammable gases, such as H , CH , etc., the use of a FTC320 with the option “glass-beads filling“ is strongly recommended. If a mixture of a combustible gas with an inert gas is present in a mixing ratio such that even adding any amount of air will not make the mixture explosive, it is called totally inert. -
