Concentration Gas System CGS

The Concentration Gas System CGS to measure the gas concentration

Aeration measurement has never been so easy.

The core element of our CGS (Concentration Gas System) is a measuring tube without any mechanically moving parts. The determination of the gas concentration is based on an innovative procedure which, in contrast to the radionuclide method, does not come involve any security issues. The CGS measures the change of the complex fluid impedance in comparison to the unaerated medium and offers decisive advantages in all fields of application concerning gas concentration (e.g. oil aeration in engines and gear boxes, foamed adhesives, aerated food products, etc.).

Key features

  • Continuous displaying of the aeration / external gas concentration in fluids
  • Inline-measuring without any mechanically moving parts
  • Suitable for all types of liquids
  • Non-destructive measurement, independent of the direction of flow
  • Integrated temperature and pressure sensor
  • Retroactive accounting of the equivalent gas content at atmospheric pressure
  • High degree of accuracy
  • Short measuring time & simple handling
  • Compact, portable measuring instrument
  • Standard digital interface (RS 232) for an optional connection to a PC
  • Analog output for all measured parameters

 

Fields of application

The measuring tube of the CGS is equipped with dash 6 connectors and can be integtrated easily into the fluid circuit. Due to the continuous measuring of the degree of gas concentration, the system offers new possibilities, e.g. for the continuous monitoring of the oil aeration of combustion engines and gear boxes, and for the optimized application of aerated adhesives. The CGS system can furthermore be applied as a regulation and control unit in all areas of technical production in which the concentration of gas represents an important quality feature, or in areas in which the systematic adding of gas can reduce the production costs significantly. The following fields of application summarize the features of the CGS:

  • Inline live data
    New criteria for the design of motors and gear boxes
  • Optimizing of machines and machine parts
    New machine elements with reduced oil aeration
  • Optimizing of fluid development
    Fluids with better gas content behaviour
  • Process survey and control
    Process optimizing in the application of aerated adhesives

 

Composition

The CGS system for the determination of the gas content in fluids consists of only two components: the measuring tube with three integrated sensors (CG-sensor, PT100-temperature sensor and pressure sensor) on the one hand, and the corresponding control and evaluating system in an electronic unit on the other hand. Both ends of the measuring tube are equipped with dash 6 connectors which simplify the mounting of the measuring instrument into the fluid circut. The CGS system for the determination of gas concentration in fluids can be used in the stand-alone mode or can be operated with any computer via the standard interface RS 232.
