Abstract. Influence of exponential smoothing on an error of result of measurement of inductance of the parametrical sensor located on a surface iron ore piece is investigated. It is established that smoothing almost much reduces an error of result of measurement at stirring influence of heterogeneity of a magnetic field of the sensor.

Keywords: exponential smoothing, the result of measurement, error, inductive sensor, quasi axial symmetry, iron ore, field inhomogeneity.
