In-situ gas analyzer
SIEMENS Process Instrumentation
Fibre optics and IR diode laser technology, standard components of high quality and reliability in communications engineering, give an extremely robust analyzer concept almost free of maintenance which enables process relevant information even under very harsh environmental or process conditions. A build-in hands-off reference gas cell avoids the need for any test gases in the field. By the means of a simple analogue modem a remote control or diagnosis of the analyzers is possible (almost) anywhere and anytime.
Today, the list of gases able to be measured with NIR diode lasers contains already gases like O2, NH3, HCl, HF, H2O, CO, CO2, H2S, CH4, ... and it is continuously growing with the state of the development in semiconductor laser technology. Additionally, high gas temperatures can be determined non-intrusively with an O2 measurement.
