Abstract :
In this paper we discuss surface acoustic wave sensors for the measurement of dynamic measurands. The sensor types and the principles of effecting by the measurand are described. For non-stationary measurands, terms like bandwidth, resolution and error limits are discussed, boundaries are given. A new method of SAW radio sensors is introduced, capable for high speed measurements. Dynamic parameters are estimated experimental results are given for these new SAW sensor devices
