Abstract : A dual pressure sensing safing and arming mechanism having a first, spring biased piston movable by a first, low fluid pressure signal to remove a first interlock on the mechanism and a second spring biased piston movable by a second, high fluid pressure signal to remove a second interlock on the mechanism is described. Upon the removal of the pair of interlocks an arming slider containing a detonator therein moves into operative alignment with a firing mechanism. A reverse order of the fluid pressure signals jams the first piston and arming slider thereby producing a fail safe condition. (Author)
