The gas transmitters Gas-TR work according to the principle of thermal conductivity (WLD\/TCD). They enable a continuous analysis of the concentration of various gas mixture components in industrial and laboratory applications. Also they are applied for mixing and production of spcial gases. The transmitters can be equipped with\u00a0 touch display (optional) ,WLAN and with various connection options.<\/p>\n

 <\/p>\n

The gas transmitters are suitable for gas analysis in corrosive and non-corrosive applications.<\/p>\n

 <\/p>\n

The principle of thermal conductivity (WLD\/TCD) is based\u00a0 on the dependance of the temperature of a heated resistance wire from the thermal conductivity of the gas which surrounds this wire.<\/p>\n

The measuring cell has two opposite measuring cuvettes (Wheatstone bridge). One cuvette is surrounded by the sample gas and the other one forms the reference. The cuvette, which is surrounded by the sample gas, changes its electrical resistance equivalent to the concentration of the gas to be analyzed. This leads to a change in the output voltage.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The gas transmitter Gas-TR has been designed for analysis of different gas concentrations. In order being able to analyse specific sample gases with the thermal conductivity transmitter (TCD) precisely,\u00a0 the thermal conductivity of the sample gas must differ significantly from that of the background gas. The gas analyzer Gas-TR can be applied in the following gas mixtures, amongst others:<\/p>\n
