摘要：A muzzle velocimeter comprising a pair of sensors positioned adjacent to the path of a projectile containing magnetic material wherein each of the sensors includes a permanent magnet having a wire coil wound thereon. The magnets provide magnetic fields which are disturbed by magnetic materials in a passing projectile causing each of the sensor coils to develop signal pulses. The distance between the sensor coils and the amount of time between the sensor coil pulses are used to calculate the velocity of the passing projectile. In an alternate embodiment a single sensor coil is used to sense the leading and trailing edges of a passing projectile, and the projectile velocity calculated by using projectile length and passing time of the projectile.
