Siemens Ultramat 7 and Calomat 7 modules for Siprocess GA700 gas analysis system

Siemens has released two analyser modules for its Siprocess GA700 gas analysis system. With Ultramat 7 and Calomat 7 (together with the Oxymat 7 module, which is already available), users can configure flexible analytical solutions for measuring oxygen, hydrogen, noble gases or infrared-active components such as carbon monoxide and carbon dioxide.

The modular design of the system enables fast module installation and replacement. Depending on configuration, the units can be used at temperatures up to 50°C, making them suitable for process control and optimisation in incineration plants and for quality control and process monitoring in chemical and petrochemical plants.

The Siprocess GA700 comprises a base unit into which one or two modules can be integrated. The modules provide sensor-based electronics, including evaluation software, as well as the process connections. The influence of interfering gases can be measured and mutually offset.

Users can employ the Calomat 7 to carry out quantitative determinations of hydrogen and noble gases in binary or quasi-binary gas mixtures. Depending on the parameter settings, the measuring ranges for H₂ are 0 to 0.5%, 0 to 100% or 95 to 100%. The module can therefore be used for pure gas monitoring and protective gas monitoring or for determining H₂ in blast furnace or converter gases.

The Ultramat 7 module carries out selective measurements of up to two infrared-active components such as carbon monoxide and dioxide. The unit can be integrated, for example, in measuring equipment for boiler control in incineration plants. Furthermore, the module can be used to measure the concentrations of process gases in chemical plants.
