Abstract : The Automated Peak Chamber Pressure Measurement System (APCPMS) was designed, built, and programmed to measure the height of the crushed copper spheres which is a function of the internal peak chamber pressure generated during weapon firing programs. A trial test was conducted with a sample size over a predetermined pressure range window. Results were compared with previously used measurement methods. By eliminating operator-error factors, the APCPMS demonstration that it was a more reliable and accurate means of obtaining peak chamber pressure measurement data. It was recommended that another computer system be used to improve visibility of display, and a more extensive test be conducted over a wider pressure range. The APCPMS consists of the following components: a gaging fixture (LVDT), a microcomputer based controller, and a printer.
