ABSTRACT:
An impact sensing arrangement comprises a pair of bodies that are separated from each other and arranged so that an impact on one of the bodies will cause it to move toward the other body, and an elongate piezoelectric pressure sensing element that is positioned between the bodies, the pressure sensing element being mechanically coupled to each of the bodies over at least one quarter and preferably at least two thirds, the width of the sensing element.
The arrangement is particularly suitable for use in an ordance projectile in which case the sensing element 10 may extend in a loop around the projectile between the nose 3 and body 2 of the projectile.
