Fluid Sensing Using Quartz Tuning Forks - Measurement Technology and Applications
Sprache des Titels:
We provide an overview about recent achievements using quartz tuning forks for sensing liquid viscosity and density. The benefits of using QTFs over other sensors are discussed on basis of physical arguments and issues arising in real world applications. The path to highly accurate and robust measurement systems is described and a recently devised system considering these findings is presented. The performance of the system is analyzed for applications such as mixing ratio measurement of fuels, diesel-soot contamination for engine oil condition monitoring, and particle size characterization in suspensions. It is concluded that using properly designed systems enables a variety of applications in industry and research.
