A NEW TWO-DIMENSIONAL TRANSDUCER FOR SENSORS SENSITIVE TO INFLUENCE QUANTITY
H. Urzedniczok
Abstract:
In this paper the important problem in measuring system: ”How to eliminate the sensitivity of sensors to the influence quantity?” is replaced by the question: ”How to use this sensitivity to measure both the main and the influence quantities?” As a solution of the second problem the frequency balanced bridges as primary signal processing circuit for parametric sensors are proposed. Structure of such a two-dimensional transducer and possibilities of its realization are described. An example of transfer functions, parameters of linear model, nonlinearity errors is given when typical semiconductor pressure sensors are assumed. Some practical aspects are discussed.
