Page 9: Principle Of Operation
Operating Manual 2.2 Principle of Operation The FTC300 sensor determines the quantitative composition of gas mixtures by measuring the thermal conductivity between a heat source and a heat sink through the gas mixture. The measuring gas is conducted to the sensor through a stainless steel block that is kept at a constant temperature of 60°C. -
Page 10: Measuring Gases And Ranges
96% - 100% On request Other gases and ranges on request The FTC300 must not be used with explosive gases. Flammable gases as H and CH may only be used in devices filled with glass balls. A gas mixture of a flammable gas with an inert gas in a mixing ratio such, that it is still inflammable for any amount of air added is called totally inertised. -
Page 11: Assembly Of The Instrument
3. Assembly of the Instrument 3.1 FTC300 Detector Unit The FTC300 detector unit consists of a hermetically sealed pressure proofed stainless steel block with a gas duct, which is suited for pressures up to 20 bar. Sample gas entering through the gas inlet is guided to the micromechanical thermal conductivity sensor and further downstream to the outlet port. -
