The sensor measures the density of liquids in a microelectromechanical system (MEMS). Within the MEMS, the liquid is directed to an omega-shaped microchannel, known as the omega chip. This tiny silicon tube – it is hardly thicker than a hair – is vibrated for the purposes of the measurement. The density of the medium to be measured can be derived from the natural frequency of this oscillation: The denser the medium, the smaller the oscillation.
The sensor measures the density of liquids during the process itself – no need to go to the laboratory. Thanks to a sub-millimeter measuring channel, the properties and quality of a liquid can be precisely monitored even in confined spaces.
