Abstract

PURPOSE: To completely compensate the output of displacement meters as to temperature, by determining the ratio of the output difference between both the displacement meters facing each other across a displaced piece, to a weighted value resulting from the addition of a prescribed offset value to the sum of the outputs of the displacement meters.
CONSTITUTION: Displacement meters 1, 2 are so placed that they face each other across a displaced piece 3. It is supposed that the displacement meters 1, 2 produce output voltage V1, V2 as to a certain displacement of the piece 3 from the middle point of both the displacement meters 1, 2 as a reference. Although the difference between the output voltages V1, V2 has only one temperature term and the linearity between the difference and the displacement of the piece 3 is high, the influence of temperature is not eliminated. The sum of both the output voltages is constant to the displacement because the voltages have inverse polarity to each other. As for the ratio of (V1-V2)/(V1+V2), the temperature term is represented in the form of a ratio and the influence of temperature is reduced. To remove the temperature term, the difference V1-V2 is divided by a weighted value resulting from the addition of a prescribed offset voltage to the sum V1+V2. The influence of temperature is thus completely eliminated.
