METHOD FOR DETERMINING CHARACTERISTICS OF OBJECTS, AS WELL AS SENSITIVE ELEMENTS OF SENSOR, WHICH IMPLEMENTS SAID METHOD Russian patent published in 2016 - IPC G01P3/42 

FIELD: measuring equipment.

SUBSTANCE: invention can be used when determining characteristics of object (speed, acceleration). Method suggests application of transducer containing sensor with main induction coil. At that, support inductance coil is used and sensitive element output signals are either signals received from said coils, or provide communication of at least one of said coils with at least one additional coil by means of core. At that, in mentioned first coils connected by means of core with additional coils, current is excited, wherein sensitive element signals are signals obtained, including from used additional coils, while before extraction of useful signals from noise, processing of sensitive element output signals corresponding to main and at least to one support coil is performed separately, due to which provide possibility of comparison of signals associated with main and at least one support coil, with each other, using electronic circuit of comparison of signals by means of which difference in them is found. Then, either on it is determined approximate value of at least one characteristic of said, using measuring electronic circuit, which can be matched with above comparison circuit, while by useful signals themselves, considering only that said approximate value and/or taking into account dynamics of change of such values approximate value of at least one other characteristics of above is determined, for this, also measuring electronic circuit or additional or said first or on useful signals and said difference and/or its dynamics using electronic analogue or digital computing devices or thereof and non-volatile memory determining accurate values of said characteristics.

EFFECT: higher reliability of sensors due to exclusion of movable parts, assemblies or molecular media.
