All sample cell and detector options of the Dx- and Cx-series analysers are available for the FCX family of analysers. Sample cell temperature can be chosen as 50 °C or 180 °C. Different sample cell path lengths are available allowing the FCX – series to be used in a variety of different applications. Analysis results are transmitted through galvanically isolated analog outputs (4-20 mA or 0-10 V). The number of gases that can be analyzed depends on the model. A relay controlled multipoint sampling system is also available.
FTIR Process Gas Analyzer
The Gasmet FCX-Series features a comprehensive range of high performance FTIR Process Gas Analyzers. The wall mounted Gasmet FCX Process Gas Analyzers offer reliable results even when analyzing complex gas mixtures. The Gasmet FCX Process Gas Analyzers incorporates a Fourier Transform Infrared spectrometer, gas cell, and signal processing electronics, a built-in Industrial Computer and aTFT-display into a compact enclosure.
The analysis results of Gasmet FCX Process Gas Analyzer are transmitted via 4-20mA Analog Output signals or digital outputs (ModBus)
The enclosure has IP 65 protection and the analyser is equipped with Vortex cooling system. The sample cell can be equipped with an optional heating and
temperature control up to 180 °C. Sample cell absorption path length is selected according to the application.
