Impulse wave overpressure sensor

The utility model discloses an impulse wave overpressure sensor, which comprises a metal sheet structure, a rubber pad layer and a base. Metal sheets of uniform thickness are processed to form the metal sheet structure, hemispheres with protrusions facing the same directions are distributed on the metal sheets, the metal sheet structure is fixedly mounted on the rubber pad layer of uniform thickness, and the rubber pad layer is fixedly mounted on the base of uniform thickness. The impulse wave overpressure sensor is simple in structure and low in price, can be widely distributed and used during warhead target damage tests, and accordingly measurements for impulse wave overpressure at different three-dimensional positions can be realized. Since the impulse wave overpressure comprises no electron members, power source is not required during measuring, and the impulse wave overpressure sensor can be used for field tests conveniently. Furthermore, the impulse wave overpressure sensor is wide in measuring range, capable of measuring peak overpressure value of hundreds of MPa (megapascal) pressure theoretically, and especially suitable for testing overpressure near the field close to an explosion spot.
