System for the exploration of signals provided by linear inductive displacement sensors.

摘要

The method and system are intended for exploiting the signals supplied by a linear inductive displacement sensor (2) provided with a primary (3), two identical symmetrical secondaries (4, 5) in phase opposition and connected in series, and with a mobile core.
<??>According to the invention
- the sum of the two AC voltages occurring respectively across the terminals of the said primary and across the terminals of the said secondaries connected in series is formed;
- full-wave rectification of the said sum of AC voltages is carried out;
- full-wave rectification of the AC voltage across the terminals of the primary is carried out;
- the difference between the said sum of rectified voltages and the said rectified voltage across the terminals of the primary is formed; and
- the mean DC value corresponding to the said difference is formed.
