Trust is good. Measuring is better!

Multiparameter controller for analog and digital transmitters with extensive analyzer functions for Industry 4.0 - integration into a large number of fieldbus systems!

Imagine: You are looking for a gas analyzer that can determine several parameters of a gas or gas mixture. Cross-sensitivities or physical and chemical restrictions force you to discard various measuring principles. This results in a colorful mix of products from different manufacturers. That means that you have many devices, high space requirements, different operating concepts of the devices, many passwords and finally the time-consuming integration into your control with various interfaces that do not optimally fit your infrastructure.

We have developed a universal controller that is unique on the market. It combines the functions of a multi-parameter gas analyzer with the possibility of integrating almost any measuring principle and this completely independent of the manufacturer!

With our CombiSens Analyzer Series you can solve the following tasks:

  • Configuration of an individual multi-parameter gas analyzer
  • Free choice of manufacturer-independent measurement principles
  • An easy-to-use graphical user interface with a highly sensitive touchscreen for all parameters
  • Uniform calibration and adjustment on one device for all parameters
  • Optional flow monitoring
  • Logging for up to 6,000 alarms
  • Expert calibration function (1-point, 2-point, 3-point and n-point calibration / adjustment possible)
  • Powerful self-diagnosis function
  • Limit relay
  • Watchdog
  • Powerful control function
  • Flexible fieldbus communication functions for IOT4.0
  • Optional fieldbus MODBUS, HART, Foundation fieldbus FF, PROFIBUS PA, PROFIBUS DP etc.

 

 

Measurement principles already supported:

  • Coulometric with P2O5-sensor
  • Electrochemical cells
  • Capacitive
  • TDLS
  • potentiometric ZrO2 cell
  • NDIR
  • WLD / TCD
  • NDUV
  • and much more

We work with almost all well-known manufacturers of sensors in gas analysis. In principle, almost any transmitter or analyzer can be integrated via a digital or analog interface.

 

Applications

  • ASU (air separation units)
  • Chemical & pharmaceutical industry
  • Petroleum and petrochemical industries
  • Metallurgical processes
  • Glass manufacturing
  • Semiconductor industry
  • Food and beverage industry
  • Heat treatment, inert gas monitoring
  • Medical applications (e.g. monitoring of medical oxygen)
  • Environmental and process gas measurement
  • Engine development
  • Compressors

 

Construction options

The example image you can see above shows a 19 "rack (2HU). It is possible to install the measuring sensors directly in the device, which is generally recommended for inert gases. For corrosive and and flammable gases, the sensors are to be installed in a separate analysis cabinet with cabinet flushing We strongly recommend that you contact us about this and together we will find the best solution for you.
