FIELD: electricity.SUBSTANCE: distributed crack sensor consists of electrical conductors of the first group and electrical conductors of the second group isolated from each other, from material of the object and environment, at that conductors of on group are not intercrossed. The electrical conductors of the first group cross with each electrical conductor of the second group at the same point under angle ?, preferably equal to 90°. The conductors of the same group are spaced from each other at the distance h equal for both groups. At that, according to the invention, in the crack sensor there are frameless double-electrode bidirectional symistors placed at the crossing point of the electrical conductors of the first group and the second group and connected by the first electrodes with the electrical conductors of the first group and by their second electrodes with the electrical conductors of the second group. The electrical conductors are thin-film, and layers of thin-film dielectric are placed so that the thin-film conductors are located between two layers of thin-film dielectric.EFFECT: improvement of sensor.2 cl, 3 dwg |
