<p>A regression sensor for detecting the regression of a surface of a solid material of a rocket motor is described. The sensor comprises: a first breaking conductor, a second breaking conductor, a first resistor connected in series to the first breaking conductor to form a first conductor-resistor pair, and a second resistor connected in series to the second breaking conductor, to form a second conductor-resistor pair. The first conductor-resistor pair and the second conductor-resistor pair are connected in parallel and placed on a support board, and the first breaking conductor is longer than the second breaking conductor.</p> |
