Abstract
An apparatus for measuring pressure includes a cylindrical tube having an open end and a closed end; a piston disposed in the cylindrical tube at the open end; an accelerometer attached to a side of the piston that faces the closed end of the tube, the accelerometer for measuring the acceleration of the piston after a blast event; and a pressure sensor located inside the tube for measuring pressure in the tube between the piston and the closed end of the tube. The apparatus also includes a data processor and computer connected by wires to the accelerometer and pressure sensor for receiving signals generated by the accelerometer and pressure sensor.
