In-situ gas analyzer SIEMENS Process Instrumentation

Fast, non-intrusive measurements of gas concentrations and temperatures, performed inside of the process itself are the domain of the diode laser gas analytic. The gas analyzer LDS 6 which combines the compact and service friendly set-up, the easy operation and the network connectivity of Series 6 with the known unique performance of diode laser based in-situ gas analytics.

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.
