Overview

Measure the density or concentration of a gas directly in the gas line or in the gas tank. 

Principle

At the heart of the sensor is a microelectromechanical system (MEMS) with an oscillator in the form of a tuning fork. The natural frequency of the oscillator varies depending on the density of the gas surrounding it. 

Application

• Monitoring of welding gas mixtures

• Monitoring of gas mixtures for food packages

• Monitoring of clean gas

• Concentration of binary gas mixtures, ideal volume percentages (=molar percentages ) in %standard density

• Permitted gases or mixtures of such gases:

          Nitrogen (N2)

          Oxygen (O2)

           Air

          Carbon dioxide (CO2)

          Neon (Ne)

          Argon (Ar)

          Krypton (Kr)

          Xenon (Xe)

          Hydrogen (H2)

          Methane (CH4)

          Natural gas (maximum permitted helium concentration: 50 ppm)

          Ethyne (acetylene) (C2H2)

          Ethene (C2H4)

          Ethane (C2H6)

          Propene (C3H6)

          Propane (C3H8)

          Butane (C4H10)

          LPG (supplied as gas)

          Other media may be used after individual clarification.
