Изобретение относитс к электрическим измерени м неэлектрических величин и может быть использовано при измерении толщины крупнегабарит- 5 ных объектов преобразовател ми, контактирующими с поверхностью объекта контрол .The invention relates to electrical measurements of non-electrical quantities and can be used when measuring the thickness of large-sized objects with transducers in contact with the surface of the test object.
Известны динамические способы передачи сигнала преобразовател .не9- {0 лектрическрй величины в электрический сигнал в которых выходной сигнал преобразовател линейно преобразует- , с во временной интервал 1,There are known dynamic methods of transmitting a signal of a non-9– {0 electrical voltage converter into an electrical signal in which the output signal of the transducer linearly transforms - in time interval 1,
Однако это не обеспечивает линей- |j ной зависимости медду временным ИЕНтервало и измер емой величиной.However, this does not provide a linear dependence of the medical time interval and the measured value.
Наиболее близким по технической сущности и д остигаемому результату вл етс динамический способ линеа- 0 ризации характеристик преобразовател заключакицийс в том, что заранее измеренный сигнал преобразовател и известный опорный сигнал измен ют,,, начина с заданного момента времеии, 25 по экспоненциальному закону с разными посто нными времени, причем первый из них - до заданного значени , -и фиксирует интервал времени ме аду мсихентом возбуадени переходногоThe closest in technical essence and achievable result is a dynamic method of linearizing the characteristics of the converter in such a way that the previously measured signal of the converter and the known reference signal change ,,, starting from a given moment of time, 25 exponentially with different constants time, the first of which is up to a given value, and it also fixes the time interval between the moment of transition

процесса и моментом достижени заданного уровн . В известном способе преобразование осуществл ют на начальном участке экспоненты. Входной величиной преобразовател может быть любой физический параметр, воздействующий на индуктивный емкостный или резистивный датчики, линейно преобразуемый в интервал времени 2,process and the moment of achievement of the set level. In the known method, the conversion is performed at the initial portion of the exponent. The input value of the converter can be any physical parameter acting on an inductive capacitive or resistive sensor that is linearly transformed into a time interval of 2,
Однако, если ме.жцу измер емым физическим параметром и вариируемым параметром преобразовател нелинейна зависимость, то оказываетс нелийненой и зависимость между измер емам . физическим параметром и интервалом врелдани. Кроме того, в р де случаев удобно использовать не интервал времени , а аналоговый выходной сигнал в виде напр жени .However, if a human being with a measured physical parameter and a variable parameter of a converter is a non-linear relationship, then the relationship between the measured values is non-linear. physical parameter and interval of vreldani. In addition, in a number of cases it is convenient to use not the time interval, but the analog output signal in the form of voltage.
Цель изобретени - линеаризаци характеристик преобразовател видаThe purpose of the invention is the linearization of the characteristics of the converter
