Capacitive analog transducer of large displacements

Conclusions Test results indicate that a linear analog capacitive transducer is suitable for indicating displacements over a wide range with an error not exceeding 2·10_–5. The design relationships and formulas provided above can be used for evaluating the structural factors and parameters of the transducer, which affect its precision, and to make the transducer meet given requirements with a minimum of trimming work. A capacitive linear analog converter of displacements into an ac voltage amplitude is a sufficiently simple device which can be widely used in systems requiring precise measurement of large displacements and lengths.Translated from Izmeritel'naya Tekhnika, No. 8, pp. 15–18, August, 1968.
