SONOS Gas Analysis Systems
SONOS systems are based on the acoustic measuring principle. With regard to application, this measuring principle is supplemented by additional measuring processes, such as heat tone, heat conduction or IR measurement, paramagnetic process or selective semi-conductor sensors.
SONOS systems measure every kind of gas, even hot, aggressive and corrosive gases.
What is the acoustic measuring principal?
- The principle consists of a conversion of acoustic vibrations into electrical signals
- The acoustic vibrations are created by the gas to be analysed flowing through a cavity oscillator
- The frequency of the acoustic vibrations is proportionate to the sonic velocity of measuring gas
- Continuous measurement of the gas concentrationWhy is acoustic gas analysis applied?
The gas concentration measurement by means of the acoustic measuring principle is mainly applied for tasks in which stable and reliable analysis values are continuously required over a long period of time.
Acoustic gas analysis can be performed on any type and composition of gas.
Advantages of this measuring technology are:
- Free choice of media-contacting parts
- The measuring cell is high vacuum tight and high pressure tight
- The measuring cell does not present a source of ignition
- Continuous and direct measurement during the process
- No sample drawing
The SONOS systems can be integrated in any technical processes due to the application related design of the gas interfaces, process interfaces and electrical interfaces.
